Marine intake

I have the marine intake swap on my 5.7 and love it.

but I have a fuel pressure problem.

does anyone have a gm part number for the fuel pressure regulator.


thanks james

You wont find a GM part number as its not a GM automotive part. You'll find a Mercruiser p/n or similar. BTW They are a 4 bar or 58psi FPR. At WOT it will allow 58 psi and during cruise about 52psi of fuel pressure.

IIRC A FPR from a 97-98 LS1 Corvette will work.

Its still a GM regulator. The GM TBI Marine regulators had a GM part number when they were available.
