Genesis Fuel Pump For Custom Gas Tanks

IMG_7480The Genesis 1 fuel pump is the answer to putting an electronic fuel pump in a custom tank and not having to use a dash to cover the fuel pump on the top of the tank. It only needs a 2 ¾” hole in the bottom of that tank to insert the weld in bung for the pump.

The Genesis is available in forward and rearward facing pump depending on the configuration of your tank. It is set up for a low fuel light like the Sportster is. It has the same fuel pressure as the stock HD pump. The Genesis pump is available exclusively from Fat Katz Inc. 530-268-2232

    Make sure you have plenty of fuel before attempting hard acceleration. The configuration shown will allow fuel to shft to the rear of the tank uncovering the pick up under the pump at low fuel levels. I know tank mounting angle can make it worse or better, but I have my doubts about the forward pickup configuration shown.

    bigwave916..your so smart you cant see the forest through the trees….looks like don has placed a nice baffle behind the pump to prevent starvation under acceleration?..the manis very smart and wouldnt sell a product that doesnt work.

    Why not use an old BMW fuel pump? They’ve been running them in tanks for years and you can access them though the fuel cap.

    A1 – he, he, he…

    As noted before – there are so many self fabricted/made alternatives; do not expect to make your 1st billion selling these.

    Lyle,
    Why pay $400 for a BMW pump when a $85 Ford Focus pump will do the trick.
    My K model Beemer got me from CA to Sturgis and back with one in the tank.

    But going in through the Gas cap still wont help with the wiring or the baffling

    Well A-1, I guess I’m not as smart as I thought I was….either that or I need new glasses.

    I was going to say it’s a ripoff of a thunderheart pump from damn near 10 years ago and it is, but after looking at fatcatz website they do give credit to thunderheart. I think that’s pretty cool and shows honesty in their company

    Fat Katz quality has always been there, i’m sure it won’t dissappoint, not the least expensive but never had an issue with any of their products

    I appreciate all of the input on our new pump assembly. Yes it was designed by Thunder Heart several years ago and then they discontinued it and we purchased it. When you think of all of the options of automotive fuel pump out there you go crazy, the Genesis 1 makes it real easy to install and it will put the pump in the lowest part of the tank. Easy installation means that you just might be able to make a profit on the sale and install. You have to deal with the slosh of the fuel but the HD tank is the same. As the trends come and go the long tanks create a challenge for fuel slosh, that is the nature of the beast. We currently make a forward facing and rear facing pump depending on the angle of the tank. Thunder Heart really did their home work and they designed this assembly. It has an incredible amount of machine work in it and you know what that means, it cost more. We have used a lot of these in our tanks and they have worked great. The ease and flexibility makes it all worth it. Think about using the Sportser set up in tank with a lot of curve on the bottom and the box that you are going to have to build, then the pump in absolute worse place in the tank. Anyway thanks for your input

    Thanks

    Puzzled, rather baffled, how to get tank wide slosh plate baffle in place and weld through 2-3/4 hole?
