How do i go about connecting the feed and return from a Corvette style regulator / filter back to the stock fuel lines on my 96 Tahoe ? Are guys just using injection rated hose and clamps ?

Just curious why not just use the stock setup that's on the Tahoe? Seems it is adequate for a ls swap.

The engine i bought has a returnless fuel rail so unless i swap over to a return style fuel rail i have to swap out to a Corvette regulator.

I used -an lines and fittings. There's a few threads on here to find the right sizes for the fittings.

I know I could go all an lines just wondering if it possible to us my current fuel lines as they are perfectly fine.

I may be wrong Houston but I think you should be able to. I've got a 96 z71 and it's got a single fuel line to the engine but I think the fuel pressure regulator is in the intake on the vortech 5.7. I think they provide ample pressure just not sure about a regulator.

Not a tahoe swap, but on my bimmer I went with Dorman barb fittings and SAE R9 rated fuel injection hoses with fuel hose clamps. For the filter/regulator feed line I bent and flared new 3/8" tubing.

AFAIK fuel pressure on a TBI engine is much less than a EFI and your factory hoses are probably 30R7-rated (or equivalent) which has a max rating of 50psi. You might wanna upgrade your lines to R9-spec.
