79 - Fuel pump replacement
I am trying to remove and replace the mechanical fuel pump but space seems to be awfully tight to remove the two bolts. Is there a trick I am missing?
As to why I am replacing the fuel pump, let's leave that for another thread that I have going. I just need some removal tips for tonight...
Thanks!

Some remove the front tire for access and go in through there. Myself, with front up on ramps I used a 3/8 drive with a 10" extension. The ratchet will end up way over by the tire but the pump bolts came out easily. Don't forget the pushrod "hold bolt" on the front of the block.

Grease will hold it up there.
When installing the new pump align the timing marks to zero on the compression stroke.
That puts the push rod on the heal of the cam.

I had the car on jackstands, with the wheel off, to get access to the bolts. It was not a simple fix. I did most of the work from under the car. If you forget the bolt, you can grease the pushrod to keep it in place.

Also, be ready to plug the fuel line. With the gas tank higher than the pump you could have a empty tank by morning and a garage floor half full.

That I got. Removed and plugged fuel lines from pump and removed the passenger front tire. I can see the bolts are accessible now. I am just trying to turn the crank to line up the timing marks on #1 compression - easier said than done -

I turn the engine with the alternator pulley nut. I have to squeeze the belt together some so it won't slip. Turns easy with socket and breaker bar. Better than trying to turn the crank bolt.

Good point - have not thought of that - anyway, I did remove the pump and I can see now why the timing marks have to be lined up - I can bury the pushrod in the block when I install the new one in and not have issues trying to compress the pump lever while I install the pump. I did remove the mount plate as well so I just need to get the gasket and should be able to install the new one tonight.
