The corvette reg i have is spose to let 60psi to the rail,

so SDPC is sending me a new one.

Now im wandering if i need a vacuum refenced type of reg to go with my return style system??

Man just when i thought every thing was going good.
Check into what we discussed.

Pat, you lead me down the right path again!

Talked to Lonnies performance tonight. Great guy, very knowlegable on fuel systems.

The reg i have will be fine up to 600RWHP.

But im having him set me up with a boost ref. reg and fittings for no worries.

My fuel rails are good.

Thanks Lonnie for the Help!!

Does this affect an '06 5.3? Is it return or returnless?

I got a R-tvs1900 too, I'm going to install it in a few days so I'm doing some research.
Thanks

Yours is returnless. You should be ok with just a fuel pump change, but i would call Lonnies and find out for sure. Better safe than srry.
