    I would agree with this as well. Wouldn't hard turns (exposing one of the pick-up's to air) cause the fuel system to suck air instead of fuel out of the other pickup?

    I dont see how this would work a whole lot better than the factory pickup (especially for EFI) if there isnt more baffeling/chambers

    Just placed my order with APE came to $102 with free shipping and $11.99 for 12 hard drive magnets off of ebay shipped.

    This is what I ordered, i think this is pretty much PolarBear got:

    1 x MP-15 with bleed hole (pass through)
    2 x MP-12 without bleed hole
    1 x 14" flex hose
    2 x 10" flex hose
    1 x 8" flex hose
    1 x Y adaptor for flex hoses

    The only thing I have left is to order the fuel line clamps, I need to decide whether to use this style:

    or this style (oetiker):

    Those pick ups work like a check valve, when it loses fuel it closes and the pump will draw from the other pick up. I have the Vaporworx system (uses the same style pucks) in my car and I'm able to run auto-x with 1.5 gallons in the tank without a hiccup.

    Thats pretty close to what I bought. I used more of the 14" hoses, but there is a bit of slack with them. I also used the oetiker clamps as described in the Vaporwerx thread on LS1tech or PT, They are really nice clamps, but you need pinch pliers to clamp them. I got everything from McMaster Carr as it is only a few minutes away from me. Cant link to anything on McMaster Carr's site because of the way it is written. but search for 5435K12 at http://www.mcmaster.com the pinch pliers are linked at the clamp area if you choose to purchase them.

    I got my fuel pump in the tank last weekend finally. I went with an external Walbro, two band clamps clamped to the pump and another big ass hard drive magnet that I had from another OLD hard drive. When I put the pump in the tank I got it stuck to the one pickup and I almost couldnt get it off with one hand. Once it was in the tank and in the spot I wanted, I tried to move it around and it was VERY difficult.

    This should work out well.

    I had to trim the bolts for the band clamps, otherwise it wouldnt fit through the sending unit hole.

    No cutting or welding!

    On a side note; Once I was finished I tested to make sure the pump was working and I fired up the pump with about 3 gallons of fuel and a bucket. I wanted to get the rest of the fuel out of the tank so I waited until I heard the pickups suck closed. On a flat surface once completed there was only a few ounces of fuel left in the tank, yeah this should work very well.

    polarbear, where did you mount your pump? on top of the tank with a magnet? since my efi will need a return line i was thinking of using the original 3/8 fuel line as my return line and run a new 1/2 aluminum line for my new fuel line. i was thinking of getting a metal nipple welded into my new tank hole cover? what do you think? i am also concerned about having a 5/16 pick up line. yaw think this will have an issue supporting 600 to 800 hp?

    polarbear, were u able to install your system thru the factory sending unit hole? so you did not have to cut up a new tank

    I dont see any issues with putting magnets in the tank.

    The pump is in the tank, somewhere in the middle near the sending unit.

    I was able to get all the parts that I have posted in the stock sending unit hole. No cutting or welding on my tank
