    Well it's time to get a new fuel pump for my K5 so I would like to hear from my fellow brothers & sisters what type of mechanical fuel pump do you have/recomend for replacing my stock pump on a 350 with an Edelbrock 750cfm 1901 Q-Jet???
    Thanks

    I bought a brandnew Holley High Volume from Jegs for $53 and the damn thing hits the motor mount so I couldnt bolt it up. Well the inlet tube hits the motor mount. If I were to buy the holley that rotates, I could simply turn the inlet around. Anyways, it just sits in my garage right now. $53 lost. Oh well.

    When I built by SBC last winter I used a plain old stock fuel pump. Nothing fancy 20$ at Advance auto parts and it has done me good.. I have ran the thing dry 5-6 times (I should say my WIFE ran the thing dry) no problems. I have holley Qjet and edelbrock performer intake. It keeps up with everything good.

    I have just installed the Holley 12-327 pump for my #1902 Edelbrock carb a few weeks ago. No problems at all. The pump is rotateable. I had no problems clearing the engine mount.

    Electric fuel pumps work well with a fuel reg valve. I ran one on my 73 Road Runner (440). It provides a constant pressure and you can adjust it when you see fit. I'm going to put one on my 74 Blazer before the end of the year.

    I agree with Oldsteel. I went through 3 mechanical fuel pumps when I first bought my 84(worn cam lobe on a 305) and finally switched to a two-stage electric pump installed back by the tank. I haven't had a problem since, and also noticed an increase in power, too. You'll also eliminate the chance of vapor lock in the pump in really warm climates.

    Sorry it took me so long to respond, but I just got back from chopping some fresh iceblocks for my roof. On the way I had to get out my harpoon and kill a seal for tomorrow's breakfast, as well. Good thing the sled dogs were ready!!!
