Crown Auto Parts & Rebuilding

Mechanical Fuel Pump Rebuilding Service:

When Rebuilding the original is the best way to go!

A multitude of decisions must be made whenever the restoration of a classic or muscle car is undertaken. In most cases, choosing to rebuild individual parts rather than to replace them is the best course, especially when conducting a true restoration when correctness and originality are considerations. This is especially true when the car being restored has nearly all its original parts still intact. At Crown Auto Parts & Rebuilding we specialize in rebuilding matching numbers parts for classic cars and trucks to help you keep that classic matched and on the road to handle today's modern fuels.

With the alcohol that has been added to most of our gasoline, fuel pumps are often the first part on the engine to suffer. Alcohol attacks the old style rubber diaphragm materials that were not alcohol resistant. This can cause fuel pump failure. If you have purchased a New Old Stock (NOS) fuel pump, it is recommended that the diaphragm is replaced before attempting to use it.

Another problem is that the new alcohol gas tends to break down faster than non-alcohol gas. This can cause problems due to the gummy substance that is formed when the fuel breaks down. It can plug fuel lines, fuel pumps and carburetors. In addition, it can cause intake & exhaust valves to stick, causing bent pushrods and other problems.
