The 0 2208 Fuel Pump: What You Need to Know About This Classic Carter Marine and Automotive Pump

If you have a Carter 0 2208 fuel pump on your hands, here is the bottom line: this is a mechanical fuel pump originally designed for marine applications, but it also saw widespread use in classic Ford trucks, muscle car engines, and even some vintage boats from the 1960s and 1970s. It is a workhorse pump that delivers about 30 gallons per hour at 4-7 PSI, runs on 12V DC, and is compatible with both gasoline and diesel fuels. However, finding a direct replacement or rebuild kit can be tricky because the 0 2208 has been discontinued for decades. The good news is that there are modern alternatives that work just as well, or even better.

What Is the Carter 0 2208 Fuel Pump?

The Carter 0 2208 is a mechanical fuel pump that Carter manufactured for a variety of engines. It is a compact unit, measuring roughly 4.5 x 3.5 x 3 inches, and weighs about 2.5 pounds. Its housing is made of corrosion-resistant aluminum, and the internal components include stainless steel parts and Viton seals, which makes it durable enough for both marine and automotive environments .

This pump is designed to handle fuels with a viscosity of up to 1000 SUS (Saybolt Universal Seconds), which means it works well with gasoline, diesel, and even some heavier fuel blends. It operates in a temperature range of -40°F to 200°F, so it can handle extreme cold and engine heat without issues .

Where Was the 0 2208 Used?

The 0 2208 was not limited to just one type of vehicle or engine. Here are the most common applications:

1. Marine Engines
The pump was originally marketed as a marine fuel pump. It was used in various inboard and outboard engines where a reliable, corrosion-resistant pump was needed. The aluminum housing and stainless steel internals made it a good fit for saltwater environments .

2. Ford Trucks with FE Engines (1965-1969)
According to Ford truck enthusiasts, the 0 2208 was used on Ford F-100 and F-350 trucks equipped with the 352 cubic inch FE engine, as well as later 360 and 390 FE engines. The original Ford part numbers for the fuel pump were C3AZ9350R, C3AZ9350U, and C6AZ9350B. In 1972, Ford replaced all three with a single Airtex pump marked RD-410-MF .

3. Chevrolet Small Block V-8 Engines (1960s)
The 0 2208 also popped up on first-generation Chevrolet 265 V-8 engines from the early 1960s. In one documented case, a 265 V-8 that was being dyno-tested used a Carter 0 2208 to deliver about 5 PSI of fuel pressure to the carburetor .

4. MasterCraft Ski Boats (1980s)
A 1988 MasterCraft ProStar 190 ski boat was found to have a Carter 0 2208 as its original mechanical fuel pump. The owner was searching for a replacement because the pump had failed and was no longer available from standard auto parts stores .

Can You Rebuild a Carter 0 2208?

This is a common question among owners of older vehicles. The answer depends on which version of the pump you have.

Rebuildable vs. Non-Rebuildable Versions
Carter made two versions of the 0 2208. One version is held together with many small bolts, which means you can open it up and replace the diaphragm. The other version is crimped together and has no bolts at all, making it non-serviceable. If you have the bolted version, you can try to find a rebuild kit. However, rebuild kits for the 0 2208 are not easy to find today. Some sources suggest that the internal part number for the 0 2208 is M4907, but that does not guarantee a rebuild kit is available .

What About the Filter?
Some versions of the 0 2208 came with a fuel filter canister attached to the bottom of the pump. If you have an inline fuel filter installed in your vehicle, you can skip the canister version and use a later model pump that does not have the filter housing .

What Are the Common Problems with the 0 2208?

Even though the 0 2208 is a robust pump, it is not immune to failure. Here are the most common issues owners report:

1. Fuel Pressure Too High or Too Low
The 0 2208 was designed to produce about 5 PSI of fuel pressure. Some aftermarket replacement pumps for Quadrajet carburetors can pump out up to 9 PSI, which is too much for the needle and seat in a WCFB carburetor. Too much pressure can flood the cylinders, cause ring wear, and even lead to hydro-lock .

2. Accelerator Pump Issues
In some cases, the accelerator pump mechanism inside the carburetor can become maladjusted. This means the pump does not push enough fuel into the primaries when you open the throttle. The fix is usually a simple adjustment, not a full pump replacement .

3. Diaphragm Failure
Like any mechanical fuel pump, the diaphragm inside the 0 2208 can dry out and crack over time. This leads to fuel leaking into the engine's oil pan or onto the ground. If you catch it early, you might be able to rebuild the pump. If the diaphragm is torn, the pump will not build any pressure .

4. Hard Starting and Stalling
If the engine is hard to start or stalls under load, the fuel pump is a likely suspect. The pump may be building pressure but not delivering enough volume. A flow test is the best way to confirm this, but most mechanics will recommend replacing the pump if it is more than 15-20 years old .

How to Find a Replacement for the 0 2208

Since the Carter 0 2208 is no longer manufactured, you have a few options:

Option 1: NOS (New Old Stock)
Some auto parts stores and online sellers may still have NOS Carter 0 2208 pumps sitting on a shelf. These are genuine Carter pumps that were manufactured decades ago but never sold. They can be expensive, and there is no guarantee the internal seals and diaphragm are still good after all these years.

Option 2: Cross-Reference to a Modern Replacement
The 0 2208 has been superseded by several different part numbers over the years. For Ford FE engines, the original Carter pump was replaced by the Airtex RD-410-MF and later by the Airtex 6523 (with a fuel filter) or the Airtex 4194 (without a filter) . For Chevrolet applications, the Carter GM5904P is a modern mechanical pump that delivers similar performance .

Option 3: Upgrade to a High-Performance Replacement
For many owners, the best option is to upgrade to a modern, high-performance fuel pump. This is especially true if you are using the engine for performance driving, towing, or marine applications where reliability is critical.
