Is this a thing?
I patched a couple feet of fuel line on my 02 corolla. It uses 5/16 line and I think it's returnless, not that it matters. Anyhow I hacksawed the old stuff out and put a couple feet of new metal in. There's a vinyl quick release coming from the tank and since its o-rings were leaking and I couldn'd find a splice-in part, I lopped it off and used a proper vinyl-steel fitting there, too.
If you look at these fittings closely there's an "internal tunnel" projecting into the line, presumably to brace everything against the compression the ferrule enforces. This seems like it uses a considerable amount of cross area.
I "gunned it" and seemed to fall flat at 2/3 throttle and 4500 RPM. I don't want to burn any valves from running lean. I'm not familiar with the car, just picked it up, so IDK if it always ran like that or not.
-- Does anyone else think 5/16" is barely sufficient to power a 130ish HP car to begin with?
-- Any studies out there on these stupid fittings?
-- Any replacements or other techniques that would work? I could use a few inches of SAE 30R9 injection hose and clamps for the all-steel junction, for example, but not the vinyl-to-steel part. The female quick releases available to me have 3/8" vinyl and 5/16" connectors "or vice versa" but no straight 5/16.
I have a 5/16 barb that I tried (and failed) stuffing onto the cut vinyl line. Its ID may be slightly better than the compression fittings, though it's still a reduction.
