sure heres the obvious two.....one of the bolts you get at through the fender well with a really long extension....the other is that there is a bolt inthe fornt of the engine and if you replace it with a longer bolt it will hold the fuel pump rod in place....not a very good description but maybe some else will chime in....and have a bucket cause gas is going to siphon fromthe tank....

I have seen a detailed procedure for replacing the pump but cannot find it..
The gas tank is full this might be a problem. any ideas
The long bolt it is not the mounting bolt for the fuel pump -- right ??
Is it easier with the passenger tire off and the car jacked up??

I never replaced the fuel pump but I did replace the metal line from the pump to the carburator. Drive it until it's nearly out of gas before you start and then jack the front up slighly to prevent gas from running out the line from the tank. Also get some flare nut wrenches.

dont know how different a 71 is from a 78, but on mine you would pull the fuel feed line and stick a bolt in it or fold it over with a nylon tie.
remove return line/vent line
remove the two outer bolts that hold the pump to the plate
remove pump and set aside
remove two inner bolts that hold the plate to the block, and remove plate.
remove fuel pump rod and inspect.
clean all mating surfaces and if all parts are ok
apply heavy grease to fuel pump rod and insert. this will hold the rod " up "
install mounting plate with gaskets and sealer
install new pump with gasket and sealer, making sure rod did not drop
install fuel lines
it will crank longer than normal, to fill up the lines and pump.
i did not remove any wheels or come in thru the fender at all. maybe a 71 is different

I did mine on my '71 a couple of months ago.
I replaced the two fuel lines while I was in there. If you do replace the fuel lines, be quick when switching them...they'll pour gas out like crazy when disconnected.
Also, the rod that actuates the fuel pump will sometimes try to slip out, so I used some grease to help hold it in place.
Good luck...

Thanks to you the fuel pump project went pretty smooth.. I wanted to extend my thanks to you and add a few things to your procedure.. The bolt in front should be about 1 1/4" long and should go in a good inch or so. Mine didnt go in all the way as I took the finger tight to heart.. Anyway it will still work in place of the grease.. Mine had a little burr in the threads and didnt go in all the way.. But I probed with my finger and could feel the bolt come thru the block into the chamber as I screwed it in with a socket..
Here is a tip . The vanilla rubber fuel line I had replaced earlier had a kink in it. The guy at autozone suggested using fuel injection hose . It is stiffer and resist kinking..
I also replaced the fuel line running from the pump to the Carb. It had a kink in it at the carb..
The car seems to run a little better now and is more responsive..
Thanks Agin!!!!
