Hello. Was searching for fuel pumps for the ls4. Will the ones being used for the 3800sc swaps be ok, like the Bosch 69225, ep 376, ep 386, or the ep 381? The ls4 will have upgraded headers, ls2 intake manifold, ls 1 ported tb, and ls2 injectors and fuel rail. Thank you in advance.

Rickady88GT used a factory LS4 pump in his, replacing the whole Fiero sending unit: https://www.fiero.nl/forum/F...ML/000114-2.html#p76

We have an LS2 GTO fuel pump which We plan on using on Our LS4.

We think most everyone else is using the Walbro 255 pump.

I am using the E3270 fuel pump (1996 LT4 and the L31 Vortec truck fuel pump). It is a direct drop in fuel pump into the fiero fuel tank. It is rated to flow 50 to 60 gpm and maximum pressure in the 80-90 PSI range.

Thanks for the info guys. I may be picking your brains more on this swap.
