    Just curious, can you use the factory 3/8" fuel line, flare it at the front-end, and run a short piece of braided line to the pump? I have an electric pump ready to go in my car, but I would like to keep the fuel system as simple as possible and I was thinking this pump might do the trick. Also, would a return line be needed, or can I run it like a factory '70 setup? Thanks

    Rob,

    Yes, that is possible.

    How much this will limit the pump is an unknown, and if it would work for you depends on how much your asking from the pump... or in other words, how much fuel your engine will demand, and how the other factors in the car (acceleration forces against the fuel, and line/pickup sizing) will affect it, in your particular combo.

    Generally speaking, more fuel system than you need is a good thing. No such thing as "too much" fuel system capability. Too little fuel delivery on the other hand can lead to all kinds of bad things.. from simple poor performance, to ugly engine damage.

    So if you did this, a fuel pressure gauge, and careful monitoring of that gauge would be critical.

    The worst thing that will happen is you have to upgrade the feed lines/pickup assembly. No question that the pump itself could feed the motor, as I have had it on 600+ HP motors, and it has not even been "taxed" to keep up with those engines.

    And yes, this pump does not run a return line.

    Jim, that's music to my ears! lol. The one thing I would need to do is upgrade my sb fuel line to a 3/8". I think I'd rather go through the trouble of lifting the body off the car just enough to put the larger line in than going through the trouble of welding a sump in my tank, routing new braided lines, and finding a spot to mount my electric fuel pump and filter. Btw, can you retro-fit a 350 arm in the pump and do you have any in stock? Thanks

    Yes, we do have the 350 version of this pump.

    I also have a complete Fuel system kit, that comes with a bigger stock pickup, and 1/2 push-lock hose, that can be installed while keeping the rear section of the fuel line in place. The fuel line enters the frame just in front of the tank, so it stays away from the rear end and the exhausts, and does not require removing the rear section of the fuel line.

    Only requires removal of the front section of your factory fuel line, and dropping the tank to install the new pickup.

    We are putting the prototype of the complete kit in a car in the shop this week, and I will be sending one out to John Schmidt also.

    Pricing and instructions are not done yet, but I will have this all together by the end of the week.

    Jim,
    Let me know what's all involved and the cost when you get it all completed? Thanks

    Guys..

    I will post all the info, and some pics of the installation on the TSP website, hopefully this weekend.

    So can I assume that my car is the one being used as the "mock-up" ?:laugh: Oooohhh, my 15 minutes of fame:TU:

    I am hoping for a couple sunny dry days, a little mid winter testing is what I need to get me through till spring.:3gears:
