Fast EFI Questions

[CWPottenger]

I'm Looking to install the Fast EZ EFI system on my car. What size return line should be used? Also what fuel pressure regulator do most of you use.

I run the fast 2.0 and love it. I run it with their fuel system includes reg and fuel line (although do yourself a favor and order 10ft extra as its not enough). Theit fuel line is 3/8 or -6an. I run that with an fittings to a racetronix sending unit with -an fittings. The racetronix unit though you need a -8an female to -6an male adapter

My swap is coming along well. I have another question on installation of the system. I currently have a spacer under my carb. Do I need or should I still use the spacer or because it is Fuel injection will not need or benefit from a spacer.

Tbi likes plenum space so if you can fit the space g9 for it just remember the butterfly and linkage are moved up on the throttle body so you may need a different air cleaner base. I'm running a vic jr. W/ edelbrock drop base and aN all star performance 1/2" air cleaner spacer

You want your return line to be at least the same size or one size larger than your feed line. On my 455 I have a 3/8" feed with a 3/8" return.

I'm using an SX Performance fuel pressure regulator that seems to work just fine.

I'm running an-6 lines from earls ordered 33ft., and using aeromotive filter and fuel pressure regulator. Make sure to order the proper amount of fittings and hose ends
