EFI fuel line routing

I ordered a kit from TanksInc, and I think I may have the wrong filter/regulator.

I have an SUV 5.3 with the truck intake. I guess this type of stock setup uses this type of flow system? Would you agree?




But I ordered this type of Filter/Regulator:



It seems that the above Regulator does not need a return line running from the engine. The return line out of this filter goes right back to the tank?

So, do I need to just run my return line from the engine, and "Y" into the return line from this regulator to the tank?

Or do I need to get a completely different filter/regulator?

Re: EFI fuel line routing

I have run both styles. The first style is factory on 2000-2004 truck intakes which have a vacuum pressure regulator built in to the fuel rail system, pressure line to fuel rail/ return line to tank.
Second style uses the Corvette style regulator shown, pressure line to regulator/return line from regulator to tank, no return line on fuel rail system. Both style work well but you can not mix and match.

Re: EFI fuel line routing

My 6.0 engine is the return rail style...I used -an fittings and blocked off the rail return ,and used the vett filter/reg right after the pump....either way works...but like fasttoys said ,dont mix and match

Re: EFI fuel line routing

Do you have a return line on your truck ?

I have tanksinc setup with that filter/regulator and used hotrodfuel 6AN fuel hose braid ........

But yeah - I have a 2007 truck intake (hummer) with no fuel rail return.
