    747 TBI conversion -fuel pump recommendation- electric fan

    1) Which inline fuel pumps do you guys use for a 350 TBI conversions? Prefer an OEM pump, going in a streetrod.

    2) Is it possible to flash the 747 for an electric fan signal, may just use a temp sending unit.

    thanks

    I'm using an e2000. I think its OEM for a lot of early 90's Ford applications. It supplies more than enough pressure for a TBI. The regulator will send whatever pressure is not used back to the tank.

    I would use the external mounted fuel pump from a 1987 Ford F150 5.0 liter. I would buy the Carter P74028 or the Motorcraft PF4 (If I had just won the lottery). The Ford F150 uses an intank fuel pump and the external fuel pump. For TBI only the external pump is needed.

    If I'm thinking correctly, the E2000 fuel pump is an Airtex part number, used in many Ford pickups from 1986 ~ 1991.

    I use the E2000 on my TPI engines AKA: Delco EP286, Carter P74028, Airtex E2000...it has twice the pressure needed for TBI... Was hoping there was one around 50 psi or under.

    Thanks

    That Ford pump is pretty popular. I'm using one on a LT1 engine.

    I had a Ranger at one time with the external pump. There was a canister that looked like a fuel filter on the frame above the tank but there was no filter in it. I unscrewed the cup off it to check what was inside. The little in-tank pump fed this canister. The fuel tank had no baffles and it seems to me that canister was being used as a surge tank.

    Don't know if this picture will work, but this is my 33 Chevy with a E2000 and standard GM filter.

    That's good to know..I'm installing a 95 LT1 engine in my son's 37 Chevy in the next month or so. Just finished up the alternator mounting bracket. I'm sure I'll be looking for help flashing that ECM.

    I owe you one and I'm set up to bench flash the LT1, but not sure how my health will be in next month or so, but we will try...

    There is no fan temps to use in the 7747.

    Originally those frame mounted canisters had filters in them, somewhere along the way they quit putting filters in them. On the full size trucks they also served as dual tank connection going from four lines to two lines.

    EDZIP,

    If you look in the back of a AC delco fuel pump catalog, you can get the specs on mostly all delco pumps. They will tell you the type of pump, max pressure and so forth. If you can't find it, email me and I will look it up for you. Also, airtex use to make quite a few pumps for delco, and if you can find specs for the airtex pump you can go that root also.
    If you don't have any success with the above info, call Airtex and ask for the technical dept. They have always been very helpful and will give you specs and part numbers. With a TBI 15 psi running works very well with 350's. if you have a pump that produces 30 psi max I would dare to venture that would suffice.

    Good luck, and Merry Christmas.

    Mike

    Really appreciate the offer and would like to take you up on it. Of course I'll pay the postage out and back. I still have your shipping info in my PM's.
