67 GTO fuel pump

I'm thinking I need to change the fuel pump. I've got an oil leak at it's gasket. It also lets fuel drain back down through it when not running.

How difficult is it to replace? It doesn't seem like it's that hard, but looks can be deceiving.

Thanks again for any help.

Fairly easy. Disconnect and PLUG the fuel lines. (note which line goes where) Unbolt the pump and pull straight out. Clean and prepare gasket surfaces...reverse procedure to install.

Sounds about what I thought. Thanks.

Hey... Odd question.... Do people swap them out for electric pumps? Any advantage to doing that?

Also... Is it normal for fuel to drain back into the tank through the pump or is that a sure sign this one is shot?

it is not normal for fuel to drain back to the tank like that. You could have a bad pump or carb problems....or a leaking fuel line between the tank and pump. Electric pumps are mainl used for High pressure/ high volume applications and for fuel injection....stick with the mechanical one for your car.

When replacing the pump, if it's hard to align the holes, rotate the engine 180 degrees to get the pump off the pump lobe on the cam, just bump the starter til it bolts up easily.
I wouldn't go to an electric pump.
I just put a new motor in my 70 and used the old pump and it takes a bit to start the car, so I have the same problem. But, I swapped carbs and am blaming that, but am going to swap out the pump as it is cheap. Probably just junk stuck in the check valve.

Burning rubber since 1982!!
My photobucket, lots of dif car pics.

Dang... Ames Performance is quick. I order it this morning and just received the UPS tracking number. I will likely get to swap the new pump in this weekend.

AMES has been around for a long time. They are a real good company.
