1976 to 1980 450 V8 and 6.9 2-Hole Fuel System Accumulator

It does not fit all 450SL, 450SLC, 450SE, and 450SEL models. Some had a single-hole accumulator. You MUST remove the FID cover and inspect it before ordering.

This accumulator was unique in the mid to late 1970s. It was used on all 6.9s but only some 450 V8 models. That is why you MUST know which type you have BEFORE ordering. You can clearly see the two threaded holes coming into the front of the accumulator housing.

It was difficult to find a filter to fit the correct size outlet hose. Install this steel 10-micron filter in your fuel tank outlet hose to protect your fuel pump. Clamps are provided along with a pull to plug the fuel hose temporarily to reduce fuel spills.

Fluid Maintenance - Radiator and Fuel Hose HD Pinch off Pliers

A must when changing rear mount fuel filters and pumps. Best tool for secure clamp-off in tight locations. Works on fuel hose, coolant hose and even big radiator hose.
