    Default Fuel system remodel

    The old guys are going "I thought that guy was dead". The new guys are going "who the F is this"?

    Looking to upgrade fuel system this year. Stick drawing and a couple photos of my exisiting setup (for what it's worth) and looking for ideas on how to plumb the new pieces/parts.

    Existing is a Holley fuel pump split to two regulators one for the motor and one for a 200 hp plate system.

    -8 from tanks to pump. -8 from pump to a T. -8 from the T to the fuel side regulator and -6 to the nitrous. Nitrous side goes to a -3 T and to the plates. The motor side goes -8 to the regulator then -6 to carbs (single inlet 660's).

    New stuff is a bigger/better Clay Smith fuel pump (more pressure and volume) and two new Holley 750 mech sec DP carbs so dual inlet. Figure on going -8 from the pump to some sort of distribution block and split off X 4 -8s to the new dual inlet carbs, then one -6 to feed the regulator on the nitrous side. I'm not looking to break the bank or build the ultimate fuel system here. Want each side (motor and nitrous) on it's own regulator and all fed via the one mech pump.

    Ideally would like to do this with the one pump, two regulators and some sort of distribution block.

    Thanks in advance. I'm a visual kind of guy so pictures are great.

    ditch the holley regs too and get a good 4 port reg that allows to feed all four bowls. also allows for a mechanical fuel psi gauge inlet that you can go remote with and mount anyplace you want.

    WOW! Bout time Dude. I think you are gonna be pleasantly surprised. Those old 660's have done the job well but the 750's are really gonna make a difference. While you are upgrading you should really put the nitrous on its own system, own pump and regulator. Magnafuel has a really nice one very similar for less than half. I think Joey has the one I am referring to on his boat. Use the magnafuel for the carbs and use a holley bypass for the nitrous and plumb the return back to a "T" on the fuel pump inlet.

    EDIT: Also I would ditch the Fram filter as mentioned. Use a Mercury water fuel seperator and an in line screen filter from Magnafuel or aeromotive or something of similar quality.

    Good to see ya back Dan! Summer can't get here soon enough.
