84 fuel pump

[John D.]

Need a new electric fuel pump for my early 84. See that someone on ebay lists a Delco EP241 pump that only fits 85-87.

Anyhow what's the scoop on the 84 pumps. Are they a one off animal 'cause of the cross-fire. Hope not. Didn't check with GM yet as I figure you guys may educate me a little so I don't come home with a one that fits all part and then find out later it's not the real deal. Thanks again, John

1984 used a different fuel pump than later C4. It uses a GM #25168719 aka Delco #EP386. This fuel pump is also used for 1982 Corvettes. It has a lot of other applications, too, but as far as Corvette goes, it's applicable to only 1982 and 1984 Corvettes. The good news is that it's a lot less expensive than the later C4 pumps.

By the way, the GM #25168719 is not the original fuel pump used for 1984 Corvettes; it's a replacement part number. The original pump was GM #6472120, aka Delco EP71.

Re: 84 fuel pump

Do not know specifically if the 84 pump is as easy to change as the 85-96 C4's. The cross-fire injected system requires less pressurized fuel supply than the 85-96 C4's. The 84-96 pumps are changed by just removing the gas lid assembly for access. You will have a good view of what else is inside the tank besides gas. My 85 was clean. Clean around the gasket sealing area to keep the trash out before removal. After installation of the new pump I used 3-M rope caulking around the circumference to keep drain water away from the gasket edge. I was surprised to find that water does find its way to this area. I even put the caulking into the indentions where the steel gas lines are installed in the removable plate. To bad the indentions were not made from the other side so there would be no holding of water until it evaporates. The rubber fuel lines are not easy to remove, be patient, would hate to have to replace the rubber/steel fuel line assembly. Other cars have to have the fuel tank removed to replace the electric fuel pumps.

Thanks Joe & Jim

Joe, You came thru with all the numbers for sure as I was hoping you would and Jim you told me how to install the pump.
Thanks very much as what as could a guy ask for except for someone to do the job for him. John

Are They Judging These On The Field Too? *NM*

Re: Are They Judging These On The Field Too?

Paul, Yes they are judging the pumps. They remove the tanks though to look at them. They do judge ur AC elements though. Boy those things took a dive. No one seems to want them. Wait until the owners find out they are history. Take care, John
