    What fuel pumps are people using in their TTs and where are people getting them from, is the 220litres per min at 12V and 275lpm@ at 14.5V suitable. What are the Specs on the standard pump.

    What bosch pumps are people using for motorsport in our cars,

    I'm running a Bosch 023, comes in between the 040 and 044.

    023 (in tank) 168L/Hr (5 bar) Max 550HP
    040 (in tank) 102L/Hr (6.5 bar) Max 330HP

    Recently had a Pierburg pull/push type external pump recommended to me by EFI Performance. About $450, flows 6.5L/min and small in size for easy mounting.

    Edit: guessing it is pretty close to the Pierburg external on this page:

    2 is pointless and overkill. Unless you intend to use your hicas lines as fuel lines (as some have done) and your car is trying to put out 1000hp, then save your money.

    Presenting Walbro, the petrol sausage. :D
    Mmmmmmm sausage! :rolleyes:

    I tried one walbro and it would only get me to 15 psi of boost before it ran out of flow (with GT28RS turbos etc.). The same happened with a standard 300ZXTT fuel pump. So now I run both pumps with dual fuel lines and a custom made fuel pump control unit (I don't like the noise of two pumps running flat out all the time).

    maybe your fuel pump controller wasnt going to full speed. Te stock TT fuel pump is plenty big enough to go to 20 PSI plus wit Gt28rs.
