Re: Electric fuel pump question
Checked out your link, you said it was in that black box with the picture of the alternator replacement? Is this the post you're refering to http://www.67-72chevytrucks.com/vboa...1&postcount=58 If so part of your problem is your pump is way to far away from your fuel tank and is above it quite a bit. Like stated before most of these pumps are pushers, not pullers so they need to be as close to, and below the fuel level as possible. If you're dead set on electric, a Holley red is probably what you want. Is there any reason a mechanical set up like stock can't be used? I would personally use a quality mechanical set up and be done with it, especially if you're not running some crazy high HP combo. I have a built 427 SBC in my 94 camaro and I played hell getting the in tank pump working with feed and return (i used a new holley sniper pump that could be regulated down for carb pressures.) When that engine comes out and goes into the truck it's getting a good mechanical pump set up.

Thanx for the advice on pumps. Really, I was leaning towards mechanical, but several guys told me stay electric. When I bought the used engine, the mechanical pump did not work, not sure why. I was a little hesitant to go mechanical since I thought there is a possibility that the issue is inside, rather than the fuel pump. Although the engine runs really well, I did have some issues such as a stripped flywheel bolt when I installed it, so I'm not confident that there aren't other issues I don't know about. Of course the fuel pump on it may just have the lever not properly inserted, and could possibly work! Maybe I should check on that...

Re: Electric fuel pump question
Going mechanical will simplify you life, reduce alternator wear, and be quieter to boot. No good reason not to.
There is a long story why I have an electric pump going back to the PO. ![]() Good luck with the mechanical pump installation.

Re: Electric fuel pump question
If you don't get the mechanical fuel pump working, post your pictures and questions about the problem you are having here on the forum, and I predict you'll get plenty of info to get you going.

Re: Electric fuel pump question
The simplicity and "road side fixability" goes up tremendously with a mechanical pump. Pick up new mechanical pump, pull the old one off and make sure there is a fuel pump push rod in the hole. then using a ratchet on the crank bolt spin the engine over and feel for the rod to move. If it's moving, stick your new pump on and plumb it up and enjoy your truck!
