Return style vs. Returnless? Ok, I have a 99 Camaro V6 body with an LS1 swapped in. I've been running the corvette filter/regulator combo for the past season with less than stellar results. I recently ordered a Fuelab regulator, to make my fuel system more reliable. However, the supplier sent me a returnless regulator, instead of the bottom return like I had ordered. So my question is, should I run returnless, like most other LS1's, or is there an advantage to running a return?
There is no such thing as a returnless EFI regulator. That would in most cases burn up the fuel pump.
Likely what you have is a 2 port regulator... 1 side is an inlet, the other a return. What do the directions say?

The 3 port would give you more plumbing options, but the 2 port will probably work just fine. Mine is a 3 port, but only two are used (one side port and the bottom return port). I switched to an up front regulator system due to the variations in pressure I was seeing with the stock, in-tank regulator. It wasn't cheap to do, but it works very well.

I'm just wondering what problems you were encountering and why the Corvette filter/regulator would not work? Did your upgrade you fuel pump?
I am in the middle of my LS2 conversion into a 2000 3.8 Firebird. I upgraded to a Racetronix FPA-001 pump and was going to use the Corvette filter/regulator to make a cleaner look of the plumbing system and eliminate the T-fuel block for my return line.
Has anyone else done this type of set-up with success?
Thanks,
Jim
