One of the performance fuel pump options, with minimal budget, is to replace the factory TBI fuel pump with a factory TPI fuel pump.

The list of pumps I've tuned includes, but not limited to:
Factory TBI fuel pump.
Factory TPI fuel pump.
Factory Vortec fuel pump.
Factory Ford F150 inline fuel pump.
Carter in-tank and inline fuel pumps.
Walbro in-tank and inline fuel pumps.
Aeromotive in-tank and inline fuel pumps.
Plain "White Box" TBI or TPI fuel pumps from Ebay. . .auto parts retailers no longer in business close out
Cleverly fabricated junk yard fuel pump from an 80's 4-cylinder Volvo.

Will the vortec pump work for me with an 18lbs spring?
