Got it mostly figured out. Going to go with the left setup in the above pic. My question now is to run a -6 line all the way back or use the stock feed line. Found a hobbs switch that you can adjust from 1-6 psi that I will use to turn the second pump on. Will I need a check valve for that pump?

 

Yes that will be fine...the stock line is 3/8 so its basically a -6 already.

 

ok, Thanks. Should I reverse the fuel filter since its suppose to flow one way?

 

Oh, I forgot you have a return system to start with....in that case, it may be better to run a new line or some how get rid of the filter. You dont need or want it on the return side.

 

ok. Ill look into it. Any idea what the thread size is for the filter. If there's an issue I should be able to use a y and use both the return and the feed to return teh extra fuel lol. Thanks

 

also, where should I Y the two lines from the bumps together? Does it make any difference?

 

Atomic, didn't you have to run some spacers on your injectors? Do you think I'll need some with an aftermarket fuel rail? The fast 65# are about 5mm shorter than my stock injectors. And if so where did you get them?

 

Dunno why I didnt think of it, but since you are currently return-style, you can just reuse the stock return line. I believe its 5/16" which should still be alright.

It doesnt really make a difference but I would tie them together as close to the tank as possible to simplify installation.

I had to space the injectors and the rails due to how the L92 intake rail mounts are. It is best to mock everything up on a table and measure to see. I got mine from FIC.

 

Ok, I'm running the tbss intake now. Don't really have extra time to mock everything up. I may go ahead and pick some up just in case. Thanks.

 

OK, Im going to pick up the fuel rails today. Im undecided between these two. The ebay ones have the crossover and fittings, but I know the Edelbrock will take me as far as I need.
