    Be sure to get a piece of EFI high pressure hose rated for inmersion and replace the factory fuel pump pulsator with it.

    I heard back from Bill at Mr. Injector and he says the injectors are 45pph, he didn't have any data to say that they were different from each other, must be pretty small difference, my local parts house also crosses both numbers to the same aftermarket injector, or other Delco numbers but again, same cross for each number.

    Going to try to modify the regulator to get 18 psi, and if I can, the 2.8L injectors should work.

    Thanks again.

    Cheers
