Zedn - You're right, Summit do have a -08 AN female to barb, I hadn't looked there. I did look at one US site but they wanted $56 postage, so I gave up. Is Summit more reasonable on postage? Only thing is the two items (push-on EFI and, AN to barb) provide the same functionality that I have with the single salvaged OEM part.

In the OEM fuel system there is a 'Y' junction (#1 from filter outlet, #2 excess return to tank & #3 to fuel rails) and the plastic fuel hose is merely a shrink fit, like the GM fitting in the earlier post, i.e. there is no bonding of the materials. I feel confident if that process is okay then an approved fuel hose and hose clamp should be fine.

I'm more than happy to hear any arguments against what I'm proposing - thanks.
