Fuel pump
How far up is the piston rod in the block supposed to go when installing a mechanical fuel pump? I have it half way up ( that's all it will go), but I can't get the pump on. I beginning to wonder if they sent me the right pump? It is definitely smaller than the one off of it. The one that was on it was Edelbock version and this one is a Jegs's model.
Thanks.
Thanks.

If you rotate the engine to Top Dead Center on the #1 compression stroke (#1 cylinder firing position) the fuel pump pushrod will be on the low part of the eccentric for easy installation. You can then coat the rod with some grease, jam it up, and slap the pump on before the rod sags back down.

Rotating the engine will make it much easier since the rod will be up and not much force will be needed to install the pump. I have a Mr. Gasket fuel pump on my Camaro and it went in with no problem.

I second the petroleum jelly/grease trick. I didn't have to use the bolt to hold the rod up (which would have required me to take my water pump off to get to...screw that). If you can get the rod where it's only sticking out about 1-1.5 in from where it feels like it would be flush in the block, that should be enough room to get the pump on. I slid the pump in there, got the two bolts started, and then used a socket to tighten the bolts down, thus pulling the pump all the way to the block. Don't worry about trying to forcefully press the pump against the block while bolting it in...you just have to have it in enough to get the bolts started.

Well, after all that and the carb isn't getting any fuel. Checked the pump and no push or pull at the ports. Looks like a bad pump. I will never get this thing finished.
Just venting. Thanks again.
