Default Need help replacing fuel pump

I've got the stock 350 V8 on my '81 and am trying to replace the fuel pump.

I've got the fuel lines disconnected and am in the process of removing the mounting bolts for the fuel pump (which lies the problem). Access to these bolts are nearly impossible. I'm wondering if I need to do some pre-work to get to these bolts. Any help would be most greatfull!

Thanks.........

The first time I did a fuel pump on a Corvette, looked the situation over & pulled the right front tire & used long extensions. Have posted that tip many times. Esp. for A/C.

also...one you get it out the piston in the block will drop. Grease it up and push it up just before you install the new one otherwise it will continuously get in the way.

I agree with Ganny and Jim. I just did mine and had to pull of the right front tire while on jack stands. That pin will fall out, just grease it and it will stay in. Also you may need to bump the engine a couple of times if it is mechanical to get the pin to set all the way up to get the pump in. good luck

If the grease doesn't work well for you, there is one bolt hole that is driled/threaded right through to the fuel pump pushrod bore. I have a nylon bolt I use to thread into that hole to hold the pushrod up. All SBC's do not have this threaded hole (I have one in my shop now w/no hole).... but most do, and yours probably does. Try the grease first... it's easier. To use the hole, you have to take stuff off the front of the block.

Just came in from changing my fuel pump. I used a long bolt through the hole in the block to hold the pump rod. I just ran the bolt in the hole, pulled the old pump. Installed the new pump and tightend it down, and then removed the long bolt. I haven't started the car yet, I wanted to come in and warm up first.
