Did a search and didn't find an answer. I've got stock returnless Vette rails and am doing a turbo 5.3. I already have the sd 60s for the ls1 intake. Do I just add an aftermarket fpr or would it be easier to get different rails?

JoeNova

Just add a regulator before the rails.

Do I not use the Vette filter/reg set up with this?

JoeNova

You can if you want to..

sean byrd

Can you give more details? If I use the vette filter/reg setup with these rails do I not need an aftermarket fpr or should I ditch the vette filter/reg and get a fpr that is boost referenced for my setup?

JoeNova

Would probably be best to get one that is boost referenced.

sean byrd

Ok so If I get an aftermarket fpr then I don't need the vette filter/reg to be clear?

JoeNova

Yes, If you buy one regulator, you don't need two.

sean byrd

Did some more searching and found that you previously had a returnless rail set up. Is it a limitation in a boosted setup? Sounds like it may be easier to ditch these and get a return rail setup?

JoeNova

I'm still running a returnless rail. No issues with fuel supply or runaway fuel pressure.

sean byrd

dod you place your fpr near the rails and how much boost do you run?

JoeNova

It's hard mounted to the rail with AN fittings. I didn't have fuel issues until 24 PSI but I wasn't even boost referencing the regulator at the time.
