Default Fuel Pump Plate Leaking

Im currently attempting to sell my vette and one of the buyers had a dealership take a look at it, in attempt to correct a couple small issues the found would a fuel pump plate leaking be corrected by putting in a new fuel pump, or is that something I can correct with an easier change?

Thank You,

Tim

Is it leaking fuel or oil? If it is oil that is leaking most likely just the gaskets for the plate are in need of replacing. If it is fuel then the pump needs replacing.

Its Leaking Oil!, Thank You, I really had no idea if this part has gaskets or seals or what. So would it basicly be a fuel pump gasket?

you need to get both a "fuel pump" & "fuel pump plate" gasket for a total cost of about $5 at most. Fuel pump mounts to the fuel pump plate which mounts to the engine and both gaskets can leak oil.

Gaskets should fix up the oil leak. Simple fix.

Here's something that's not even in my GM service manual (or Haynes, either). When replacing the gaskets, the fuel pump rod will constantly be trying to slide back out of the block. Some people use grease to try to keep in in place while re-positioning the plate & pump. My '81 block has a bolt threaded into a hole that goes all the way through to the rod. Right below the water pump. See if you have one. If you do, get a longer bolt with the same threads and thread it into the hole *finger tight* until it bottoms out on the rod. Will hold the rod in place while you do the rest of the job, eliminating a lot of cursing. Be sure to put the original, short bolt back when you're done.
