    I am needing to buy a electric fuel pump and am using a stock skylark tank with a RobbMc pickup assy http://www.robbmcperformance.com/products/1076_gmsend.html will an aeromotive A1000 pump work if it's mounted close to the tank at a slightly lower level than the pickup assy? I need to be able to support aprox 750 hp

    I would ask www.robbmcperformance.com/pro...76 that question since you already dropped youre money there. However... if you want an amatuer opinion... ( and if it doesnt hurt anyones feelings) send me a PM, be glad to go over the particulars with you. An A1000 should be quite sufficient for 750 HP in my humble opinion. This is not an attempt to "undermine" any fellow high-perf businessman/enthusiast lively hood. This is an open forum and I am simply responding accordingly.

    I am not a big fan of sucker fuel pumps for many reasons but just to mention a couple important reasons are if you get a leak in a sucker system you suck air and cause a lean condition and I have seen this a few times. One time it resulted in a nice new stroker SBC leaning out and caused $$$$$/engine failure. Fuel also vaporizes under suction and acceleration just adds to this problem as the sucker pump trys to over come the G forces there for adding to the problem. The A1000 is a very good pump that would meet most any ones needs but Areomotive has the New Phantom fuel system which I think makes the after market mechanical pumps look obsolete. For those who don't like to hear a electric fuel pump buzzzzing away this pump is in the tank/gas where you can't hear it! Check it out!

    Another issue to consider is performance w/ less than 1/2 a tank of gas. I have the RobbMc pickup assembly in my GS, with an external electric fuel pump mounted on the frame rail below the passenger seat. I have found that you cannot autocross w/ less than 1/2 a tank, and you cannot go full throttle w/ street tires in a straight line with less than a quarter tank. With slicks at a track, i would venture that 1/2 tank would be the minimum for straight line acceleration. The fuel slosh of the stock tank arrangement makes the motor go lean (at least w/ fuel injection). If the electric pump is feeding a carb, the capacity of the float bowls would probably help in these cases.
    That Areomotive Phantom system is what I plan to use the next time.

    I am mounting a Walpro 400 pump in my stock fuel tank, it is best not to use the pump as a puller... The pump I am using is enough for about 800 hp. I will need to slightly enlarge the hole in the tank and then I am cutting one of the tubes shorter on the ARob MC pickup and then the pump will be at the bottom of the tank

    Stanely,

    Is this a NA motor or forced induction? Requirements will be different for your needs if this is turbo/supercharged blow through effort than roots or NA motor.

    Just put the Aeromotive Stealth in Dads Convertible, install worked out nice and the pickup is
    is as low as you can go in the tank. Not as loud as the external that was on it. Haven't had the car out enough to test it under
    power but it seemed to be running fine with about 3gl in the tank. We plan to fully test it later this summer!
    So far I'd recommend it.

    What does the universal stealth system cost? I am seeing kits for camaros exceed $1200. For that price ill stick with a sumped tank and pump.

    no blower or turbo, just good flowing heads and intake along with a hot cam. made 587 hp on dyno and i'd like enough fuel capability to prevent any lean issues.

    You will not go wrong with Aeromotive and I think you will be very happy with that Phantom set up. I don't know why people cheap out with there fuel systems after making a big investment in there engines, it makes no sense to me.

    This doesn't have any clearance issues with the area between the tank and trunk floor. Looks like the top of the sender sits high off the tank.

    I've been running their external pump,regulated,for 10yrs now on Buizila witch is a street/strip application and love it. http://www.summitracing.com/parts/aei-11202/overview/.

    Hey, if I had a $15,000 motor I wouldn't think twice about the price of a fuel system. I am only trying to get the most I can out of a stock motor so I am just going for a bang for the buck approach.:TU:

    Mike it is higher than the stock pick up, the kit comes with two strips of adhesive foam rubber which I placed on the ribs in line with the straps. This spaced the tank down enough to clear still allowing

    you to tighten the tank securely. I placed a piece of rubber sheet over the pump before securing the tank. I mounted the pump far enough forward that the fittings are accessible with the tank installed.

    Thanks Dave for clearing that up for me.

    I know it wasn't directed at me, just clarifying my situation and agreeing with you:cool: $1,200 is a drop in the bucket considering you could loose much more by trying to save a buck where you shouldn't. Just like saving money on brakes or tires and even cooling systems. These things may not make us go faster but if things go wrong I'm sure you would wish you spent the extra cash:Brow:

    I hope you are planning to install a sump with that. Tanks Inc makes a nice universal install unit if your tank is tall enough to use it. I agree a pusher is by far the best but plenty of people get away with good-enough on a street car. You of course are very critical because of the turbo engine-melt-down factor.
