Recently there have been concerns raised on 80's cool and a bit here about fuel pumps and in particular the health of high mileage ones. Christo has had issues with fuel delivery particularly after blower installations. Some mention has also been made of a Holly replacement that may be better suited to forced induction motors. As I am a factory kind of guy, the Holly did not excite me but I thought "hey, I'm at 114k. I don't want my pump takin' a crap on me out in the middle of nowhere". So, I decided to do a PM and replace mine.
I chose an OEM pump(surprise, surprise : ), a new sock, new gasket for the pump bracket, new sock retainer and new gaskets for the high pressure banjo fitting. The total retail of these items was about 260 bucks.
I just completed the installation. It is not as bad as you might imagine. Total time was just under 1 and a half hours. Installation requires removall of the second row seats, rear sill plates, rear step plates and peeling back of the rear seat carpet. This exposes an oval access plate in the floor. Under the plate resides the fuel pump bracket. Remove the gas cap to relieve excess pressure in the tank and then unplug the wire harness. Remove the return and high pressure hoses and take out the retaining screws and carefully lift the bracket out of the tank.
After you get the bracket to the bench it is very straight forward. Un-plug the connector at the pump and take the clamp off of the hose going between the pump and the tube. Next pop the pump out. Put the new sock on the bottom of the new pump so it looks like the old one, transfer the hose and rubber lower mount over and re-assemble. Next stick it back in the tank and reverse everything you un-did. The banjo bolt should be torqued to 22 lbft and the rear seat bolts to 29 lbft.
Oh, do disconnect the battery before you start the job, no fires now.
Cheers, Dan.
