im confused on one aspect of the rubber line to -6AN conversion for the HSR.. the HSR.com says two -6AN to 14mm adapters, and ive also heard to use -6AN to 3/8" for the feed and a -6AN to 5/16" adapter for the return line. im having trouble finding this 5/16" adapter. will the 14mm adapter work? i already have the -6AN to 3/8" adapter.

I had a hard time finding the adaptors as well, so I took the hard metal tube that went to the rubber lines and had a local hose shop cut them and weld -6AN male ends to them,
.

I ran my lines right off the frame rail hard lines.

I needed one 16x1.5mm female to -6an male adapter for the feed line, and one 14x1.5mm female to -6an male adapter for the return line.

This is what my lines ended up looking like.

those are the fittings we used on my friends HSR swap we did last year. When I did mine this year, one was available and the other was on 2 month back order.

i ran bradied lines straight from the tank and back. i think that accel makes the fittings also that you need

That could get expensive for me. Just ordering 6ft of braided hose was like $60 after shipping.

Not that I wouldn't love to run braided all the way back for looks.

What I really want to do is cut off the hard lines at the transtunnel so the fuel lines can sneak up behind the motor. That would be cool

yea thats how my lines are ran. right up the tunnel
