Changing the fuel pump...
My stock fuel pump start leaking this morning.
Should I order a stock replacement from Napa, or order an Edlebrock or Holley unit from summit racing? The engine is stock w/ the Q-jet.
How much of a job is it to change the fuel pump?

I'll probably get flamed for this but I don't see spending a lot of etra dough for a highend fuel pump. Of course, it all depends on your particular application but I'm guessing that your fuel demands shouldn't exceed an OEM replacement. Changing the pump isn't a big deal. Most people have trouble with holding in the pump rod. There are two usual methods. One involves using a bolt and the other is putting an ample amount of grease on the rod and "sticking" it in place. Rather than explaining the bolt method, just use some grease. On a scale of 1-12 pack of brewskies, this is about a 2 1/2.

Use a Carter Fuel Pump
I installed an Edelbrock on my 383 originally and fuel pressure was all over the place, sometimes 4-5 and others 8-9 lbs. PSI. Returned it to Jeg's today. In process of installing the Carter which is what was on my 71 LT1 to begin with, should have stuck with OEM but the Edelbrock look neat, go with function/reliability not looks.

Use the bolt method. Get a 5/16 x 2 bolt. On the front side of the engine by the fuel pump there is a 5/16 x 1/2 bolt take it out push the rod up until it seats on the cam snug the 5/16 x 2 bolt up until you feel slight resistence and remove your fingers if the rod stays install the fuel pump and then remove the bolt and put the factory bolt back in and your done.
