Outrider70 Posted October 17, 2011 Share Posted October 17, 2011 As some of you know, I inherited my Dads 70 Monte this summer. Its in the final stages of the build and he had bought a new Holley elec red fuel pump for it. The instructions say to place it as close to the tank as possible and level with the bottom of the tank. It has a new repo factory style tank with the usual pickup tube arrangement. As anyone who has spent time under these cars knows, the factory steel fuel line runs from the tank forward to the pass side of the car at about the top of the tank (if I remember correctly...) passes over the rearend, drops down to the bottom of the body then is attached to the frame and on up to the front of the car. My problem is this; there really isn't room close to the tank, there's bearly room on the frame and the inlet and outlet on the pump are on the opposite side from where they need to be to mount on the frame. The instructions say the pump needs to be close to the tank because the pump is designed to push the fuel, not pull it from the tank. Has anyone used this setup on a Monte (or other GM A body) with a stock fuel tank? It would be a cinch if the tank had a sump and bungs in the bottom, I'd just build a bracket and let it hang below the bumper a little for all the world to see The other option is just to use a mechanical pump. To be completely honest, I'm not really sure why he chose to use an elec pump. p.s. Its carbed, not injected. Quote Link to comment Share on other sites More sharing options...
bigtankjones Posted October 17, 2011 Share Posted October 17, 2011 I am running the blue holly electric fuel pump. Mine is mounted to the front of the trunk floor. Just a hair above the stock fuel tank, and works just fine where it is mounted. I will get a picture tomorrow when I get home from work and post for you.

Outrider70 Posted October 17, 2011 Author Share Posted October 17, 2011 ok, thanks a lot. I can visiualize where you are saying, I just didn't know if it would run ok there. Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted October 17, 2011 Share Posted October 17, 2011 That is where my Magnaflow is on my 71. You can mount them up front, but they don't last very long. Quote Link to comment Share on other sites More sharing options...
72 LS5 Posted October 17, 2011 Share Posted October 17, 2011 I was in the same boat and wanted to mount it in an inconspicuous location but without cutting any lines. I got some 90 degree aluminum stock, made a bracket, and hung it off the bolt that holds the tank strap on the drivers side. Then I ran the rubber line into the stock hard line. Be sure to put a filter in front of the pump too. Good idea to get a relay switch - Summit sells a relay kit, but you will still need some extra wire (go figure!). I'd go mechanical in a heartbeat if I could, but my block has no mechanical provisioning...bummer. Quote Link to comment Share on other sites More sharing options...
bigtankjones Posted October 18, 2011 Share Posted October 18, 2011 ok, thanks a lot. I can visualize where you are saying, I just didn't know if it would run ok there. Ok. I have had mine mounted there for 2 years now with no issues. I'm running a 454 and it does not starve it for fuel. Quote Link to comment Share on other sites More sharing options...
wallaby Posted October 18, 2011 Share Posted October 18, 2011 I don't think they are particular about positioning; I mean you can mount it on its side, or upside-down, right? Maybe on its side with a 90 degree fitting on the intake and exhaust facing different directions? Quote Link to comment Share on other sites More sharing options...
Outrider70 Posted October 18, 2011 Author Share Posted October 18, 2011 It says in the instructions to mount it with the motor up. Almost sounds like a bigger pain in the butt than it's going to be worth for a fairly tame 383. Quote Link to comment Share on other sites More sharing options...
72 LS5 Posted October 18, 2011 Share Posted October 18, 2011 I wouldn't do it. You are going to spend money on tons of fittings, relay kit, wiring, pressure gauge, regulator, drilling holes in the car, and most of all, your time and the trips back and forth to the store. A mechanical pump on a tame 383 would be fine, in my opinion. Quote Link to comment Share on other sites More sharing options...
