I have a 1979 chevy c30 with the 454. I tried replacing the fuel pump, but I'm pretty sure I didn't get the rod pushed up when I tightened the pump down. I think the rod is bent.

My question is, how would I get the rod out? Also does the rod, just ride on the just like a push rod would?

One more for ya, where can I find information on the fuel lines? Like a schematic or something?
Do you

First, I don't have fuel line info on a 79. Sorry. As far as the rod, it rides on the cam (ecentric) that pushes the rod. As far as bending it, that could have happened. However, I've seen where the cam lobe has worn and no longer pushes the rod far enough. The rod should pull out for you. Was the problem the same with the old fuel pump?

Let me know.

Well, I'm pretty sure its bent, because it was sliding out, up and down. We put the pump on there, with the tip of the rod, on the edge of the arm for the pump. Torqued the bolts down real tight, because it wasn't mounting flush on the block. Pull it back off, and the rod is stock in on spot. It comes half way down the little oval opening on the side of the block.

Idk what the problem was with the old pump. We was thinking it was the pump, because it was not pumping any fuel. Checked by taking the line off the car, and cranking the motor. Cranked until the battery died. But, once we got it off, and bought the new one, I checked to see if it would make a vacuum. And it did. So my guess, is it was just out of gas. Lol.

I'm thinking about just cutting the arm off of the old fuel pump. Bolting it to block, plugging up the holes, and using an electric fuel pump. Would make it easier to start too.

It wasn't seated properly. That is why it was so hard You may be better off doing that. However, make sure to tell them what type of vehicle it is going on because your OEM pump only produces about 7 psi.

Let me know what you decide. Also, if you use the electric pump, they recommend that you run a shut off in case of a roll over. Make sure to follow the manufacturer's recommendations.
