Fuel System Fittings
 

I wanted to ask you guys...what type of fittings do you use on your track cars? Yesterday, a friend and I spent some time going over every inch of my planned E85 fuel system and mapped out exactly what fitting will go where. It was a rather humbling exercise as things quickly got out of hand and before we knew it the estimate came out to somewhere around $1300 in fittings alone. This doesn't included the PTPE (teflon) E85 fuel line (this line BTW requires a special type of AN fitting). I know fittings get expensive, but damn. Have you guys all bit the bullet and dropped that kind of money on AN fittings for your fuel system? In the end, we started considering the possibility of just going with barb adapters and using hose clamps. =X

Im still looking for a reasonable alternative or a cheaper source for ANs, but then you start having to deal with Chinese made fittings. Any info would be appreciated.

Check these guys out. Website is a little crappy but if you call you get a very knowledgeable person on the phone, usually ships out same day as well British American Transfer

Support your locals! I've bought 99% of my fittings from here:

AN Adapters & AN Hose Ends and Hose | AN Plumbing

same place for me

I've also bought a lot of stuff from anplumbing.com. Always a good experience.

In my experience, Earl's and Goodridge go together the best. Seen several Chinese Summit fittings leak. The name stuff ain't cheap but it's worth it when it comes to something like a fuel system.

I don't think you need PTFE for E85. Aeroquip's fluid compatibility chart lists Ethanol compatibility as Excellent with their typical synthetic rubber hoses --> http://www.advancedfluidconnectors.c...ility_info.pdf

Earl's has the largest openings (passages). China stuff leaks. Try to simplify what you have as much as possible.

Thanks for the input guys.
Im leaning towards this stuff:
Goodridge G-Line XF 910.
Carbon impregnated PTFE, kevlar fabric braid, light weight, and around $14/ft for -6 and $19 for -8.
Also the "olive-less" reusable fittings they make for this hose is reasonable at around $15-20/fitting.
I think Ill give it a shot.
Interestingly, I see websites listing the hose for like $30-40/ft, then most fall around the low $20s, but this plumbing monkey site has the best deals by far.
910-06 - G-Line XF Series Aramid Braided Hose -

I've used the 910 and it's great to work with. Super easy to cut and set the fittings. Very flexible. Spendy but good.

On my racecar I use 3/8" ID maleable copper tube outside along side the chassis rails and minimise the number of Aeroquip hose connections. One of the problems caused by the expense of the connectors is the downsizing the pipe sizes to reduce costs of the connectors; which reduces fuel flow and raises pump effort.
I have about £500 $600 worth of connectors on mine.
If you run the pipe inside the cabin; you must run Aeroquip steel braided the whole way with no connectors in the cabin; even at bulkheads. Counter intuitive maybe but bulkhead grommets don't spray fuel mist!

XRP all day

My build is almost all areoquip or earls anno tough, lol expensive wait still you start buying -12 and -16 at 50$ a piece plus for some fittings....

Thanks for the info guys.

I ended up getting the Goodridge 910 and their olive-less reusable hose ends.

So far Im pretty impressed. The hose is feather light and insanely flexible for teflon, and like Chris said, the hose ends are very easy to work with.
