A leaking or hardened fuel-tank bushing can turn a small maintenance job into a fuel-system problem, so getting the correct replacement matters. The wfsulee 124253 Fuel Tank Bushing is sold as an aftermarket replacement for Miller part 124253 and is listed for selected Miller Bobcat 225 and 250 Diesel engine-driven welder/generator applications. Its main appeal is simple: it gives you a direct replacement option when the original tank bushing is worn, cracked, or no longer sealing correctly. The main limitation is compatibility, because you should verify your exact Miller model and serial-related fuel-tank configuration before ordering.
Quick Verdict
Editorial Rating: 8/10, Recommended with caveats
Best For: Owners of compatible Miller Bobcat 225 or 250 Diesel units who need a replacement for fuel tank bushing part 124253.
Bottom Line: This is a practical, low-complexity replacement part with clearly stated fitment to several Miller model numbers. The tradeoff is that it is an aftermarket part, and the Amazon listing contains conflicting package-count information, so you should confirm fit and quantity before buying.

What Is the 124253 Fuel Tank Bushing?
The 124253 part is a fuel-tank bushing used in the fuel system of compatible Miller engine-driven welders/generators. Miller documentation identifies 124253 as a tank fuel bushing, while the Amazon product reviewed here is a wfsulee-branded replacement intended to substitute for that part number.
The bushing sits where a fuel-system fitting passes through or connects at the tank. In practical terms, its job is to support a secure connection and help maintain the seal around that opening. This is a small part, but a damaged bushing can contribute to seepage or an unreliable fuel connection.
You should treat this product as a replacement component, not an upgrade that increases welder output, generator power, or fuel economy. Its value comes from restoring the function of a worn sealing point when the fitment is correct.
Before You Buy: Do not order by the words “Bobcat 225” or “Bobcat 250” alone. Confirm part number 124253 against your machine’s model, serial number, and fuel-tank parts diagram. Miller documentation shows that some Bobcat fuel-tank parts changed across production ranges.
Who Should Buy It?
Best For
- You have a compatible Miller Bobcat 225 or 250 Diesel application that calls for part 124253.
- You are replacing a worn, cracked, loose, or leaking fuel-tank bushing.
- You want an aftermarket replacement rather than specifically requiring a Miller-branded OEM part.
Skip If
- Your machine’s parts diagram calls for a different fuel-tank bushing or grommet.
- You need a guaranteed OEM Miller part rather than an aftermarket replacement.
- You cannot confirm the exact package quantity you need from the current seller listing.
Compatibility and Fitment
Fitment is the most important buying factor for this part. The Amazon listing states compatibility with Miller Bobcat 225 and 250 Diesel engine-driven welder/generator applications and names Miller model numbers 902965, 903040, 903125, 903372, and 903501. That is more useful than a generic “fits Bobcat” claim because it gives you specific model references to check.
Even so, you should verify your exact unit before ordering. Fuel systems can change across serial-number ranges, production dates, and tank configurations. A part number match is stronger evidence than machine-family naming alone.
Pro Tip: Photograph the existing bushing, fitting orientation, machine model plate, and serial number before removal. Compare those details with the parts diagram and seller listing so you can catch a fitment mismatch before the fuel system is apart.
Materials and Build Quality
The seller describes the bushing as durable and made from “premium materials,” but the listing does not identify the exact rubber, polymer, or elastomer composition. For that reason, you should not assume a specific chemical resistance rating, temperature rating, or service life that is not published.
What matters most in this application is that the bushing fits the tank opening and mating fitting correctly, remains flexible enough to seal, and does not show cracking or deformation after installation. Inspect the new part before use. If it looks damaged, distorted, or incorrectly sized, do not force it into the tank.
Installation Process and Performance
This type of replacement can be straightforward, but fuel-system work deserves care. Before removing the old bushing, shut the machine down, let hot components cool, work away from sparks or open flames, and follow the Miller service information for your exact unit. Clean dirt from around the tank connection so debris does not enter the fuel system.
| Step | What to Check | Why It Matters |
|---|---|---|
| 1. Confirm fitment | Model, serial, part number, and tank configuration | Prevents installing the wrong bushing |
| 2. Clean the area | Remove dirt around the tank opening | Reduces contamination and helps you inspect the sealing surface |
| 3. Install carefully | Seat the bushing evenly without cutting, folding, or forcing it | Helps the bushing sit correctly around the opening |
| 4. Inspect for leaks | Check the connection before returning the unit to normal service | Catches a poor fit or damaged seal early |
Performance is simple to judge: the replacement should seat securely and the connection should remain dry during normal operation. If fuel continues to leak after replacement, stop using the machine and inspect the fitting, tank opening, fuel line, and surrounding components instead of assuming the new bushing alone will solve the problem.
How It Performs in Real Use
For Routine Maintenance
If you already know that part 124253 is worn, this replacement gives you a direct way to address that specific sealing point. The small size also makes it practical to keep a verified spare with other service parts for a working Bobcat unit.
For Repairing a Fuel Leak
A damaged bushing can be one source of leakage, but it is not the only one. After replacement, you should inspect the surrounding fitting and fuel line and confirm the tank connection stays dry. A persistent leak needs further diagnosis.
For Older Bobcat Units
Older machines can be more sensitive to serial-number and production changes. If your Bobcat has had a tank, valve, fitting, or fuel-line update in the past, compare the installed parts with the correct Miller diagram before you rely on a generic compatibility statement.
For Shop or Field Service
For technicians maintaining several compatible machines, a replacement bushing can be useful as a low-cost service item. The package-count inconsistency on the current Amazon page means you should confirm how many bushings will actually arrive if you are stocking parts for multiple units.
Compatibility and Safety
Because this part is used at the fuel tank, correct installation is more important than speed. Work in a ventilated area away from ignition sources, follow the machine’s service procedure, and clean up any spilled fuel promptly. If you are not comfortable servicing a fuel system, have a qualified technician handle the repair.
Do not use sealants, adhesives, lubricants, or improvised installation methods unless they are specifically approved for your machine and fuel-system components. An incorrect chemical can damage some materials or interfere with the seal.
Pros and Cons
Pros
- Uses the established replacement part number 124253.
- Seller lists fitment for Bobcat 225 and 250 Diesel applications.
- Includes several specific Miller model numbers for easier fitment checking.
- Simple replacement-part design with no electronics or adjustment controls.
- Useful for repairing a worn fuel-tank sealing point when the bushing is the confirmed problem.
Cons
- Aftermarket part, not presented as a Miller-branded OEM component.
- Exact material composition is not stated.
- Amazon package-count information is inconsistent, so quantity should be confirmed before purchase.
Is It Worth the Price?
For a confirmed 124253 application, this type of bushing can offer strong value because it targets a specific wear item without requiring you to replace a complete fuel tank assembly. The best value comes when you have already identified the bushing as the failed part and verified the fitment.
It is less attractive if you want only OEM Miller parts, if your tank configuration is uncertain, or if you need a guaranteed package quantity. In those cases, the safer buying decision is to confirm the OEM part through a Miller parts source or service provider before ordering.
How It Compares to Alternatives
A genuine Miller Electric 124253 bushing is the more direct choice if OEM branding and parts-channel traceability matter most to you. The wfsulee version makes more sense if you are comfortable using an aftermarket replacement that is sold against the same part number and stated Bobcat fitment.
You can also find larger aftermarket multipacks, such as XYZIL 124253-compatible bushings, which may suit a shop maintaining several machines. For a one-machine repair, however, fitment confidence matters more than buying the largest quantity.
Frequently Asked Questions
Is this an OEM Miller 124253 fuel tank bushing?
No. The Amazon page shows the brand as wfsulee and sells the item as a replacement for Miller part 124253. If you specifically require an OEM Miller-branded component, buy through a Miller parts channel and verify the part against your machine.
Does it fit every Miller Bobcat 225 and 250?
You should not assume universal fitment. The seller lists Bobcat 225 and 250 Diesel applications plus model numbers 902965, 903040, 903125, 903372, and 903501, but you should still confirm part 124253 for your exact model and serial number.
How many bushings are included?
The Amazon title and feature bullets state 2PCS or two bushings. However, a lower description block on the same page says one bushing, so confirm the current package contents with the listing or seller before ordering.
Can this bushing fix every fuel leak?
No. It can address a leak caused by a worn or poorly sealing bushing, but leaks can also come from the tank, fittings, hoses, clamps, valves, or other fuel-system parts. Inspect the full connection if leakage continues.
Is the exact bushing material specified?
The listing describes the part as durable and made from premium materials, but it does not identify a specific material composition. You should not assume a particular rubber compound, temperature rating, or chemical-resistance specification unless the seller provides it.
What should you check after installation?
Make sure the bushing is seated evenly, the fitting is secure, and the surrounding area remains dry. If you see or smell fuel, stop using the machine and correct the leak before returning it to service.
Who should skip this replacement?
Skip it if your parts diagram does not call for 124253, if you need a genuine Miller-branded part, or if the tank opening and fitting do not match the application described by the seller. Do not force a bushing that does not fit correctly.
The Bottom Line
The wfsulee 124253 Fuel Tank Bushing is worth considering when you have confirmed a compatible Miller Bobcat 225 or 250 Diesel application and need to replace the 124253 tank bushing. Its strengths are clear part-number targeting and specific listed fitment, while its main limitations are aftermarket branding, unspecified material composition, and inconsistent package-count information.
