Should be 3/8"

What rail? The stocks are 3/8" quick disconnect. Aftermarket are NPT, usually with a -6 AN on it.

It is a factory truck rail, with the single inlet, not the dual ones we see so often.

Returnless fuel rail...

Lol, yes. I was unsure of the correct term. I assume the LS1 Russel adapters won't fit.

The stock truck rail is 3/8" quick disconnect, same as LS1. The russel fitting will work on it.

Get the fitting w/ the screw in retainer piece, NOT the plastic crap.

Exactly. Unless you like those to pop off and burn your car down !!!!!!!!!

I already had an extra one (the plastic crap...lol) but it did not fit on the truck rail though it fit perfectly on the ls1 rail. Hmm, guess I just have to abuse it some more. In the mean time can someone shoot me a link to this "screw-on" version?

I have a plastic truck return rail, a stainless truck returnless rail, and an LS1 rail. I just checked, they all have same dimensions and the OEM metal quick disconnects are interchangable on all of them.

Thanks Gary. I may take a file to the edges of mine then. It may be rusty or something but the Rusell ls fitting will not go all the way over the hump to secure itself.
