Aeroquip socketless hose

[osubeaver]

I know the question of whether or not a given hose qualifies as "abrasion resistant" has come up quite a few times, but I just figured I'd check to see if anyone knows about this particular hose. It's part number AER-FCV0615 at summitracing.com. Here is a pic:

looks like the same stuff we use on sprintcars for some of the radiator piping and fuel return lines (Methanol). I have only seen it with push on fittings, so I doubt it would pass tech on a 3 bar fuel line, and i don't think I would trust it. That said I haven't yet seen a problem with it, and it stands up to a bit of chafing quite well. Probably didn't answer your questions but hope it helps.

I'd like to use something similar too.
3bar=44psi
The max pressure rating is 250psi, so I think the hose has no problem with low pressure fuel.

What do you think to protect the hose with a metal helicoidal wire?
In this way the pressure is OK and sharp objects can't touch the rubber.

Well, if 3bar=44psi then there shouldn't be a problem because the barbed fittings are rated at 250psi according to aeroquip. The abrasion resistance is another issue though. I guess I am mostly interested in this type of hose because it is lighter than the steel braided hose, but if it is in a gray area as far meeting specifications, then I would rather stay away from it. I know there are wraps that can go around the hose for abrasion resistance (the things that look like a chinese finger trap), but that seems to sort of defeat the purpose, as they just add weight.

look the link above, and read Brent Howard suggestion.

Maybe you could e-mail the judges... they usually do their best to answer any questions pretty thoroughly.

Absolutely, for goodness sakes nobody here can answer your question definitively, it's been discussed before with no real answer, this is what SAE is for, to answer rules questions. Only thier answer counts, and it's only an email away...

I just need enough to tide me over until I need more.

[V2 - Italy]

Yes Charlie, but I'm still waiting.

that is the exact hose we used for our fuel system last year... with barbed AN fittings pressed in.. not saying for sure if you guys will pass with them, but we did http://fsae.com/groupee_common/emoticons/icon_wink.gif

btw.. those SAE 45 degree barbed fittings never come back out, you have to cut the hose down the side to remove them

but I would email SAE just so there's no discussion

I suppose I will try to contact them. I hope I will get a reply.

[James Waltman]

If they give you a response will you post it here so we can all know.

Thanks

GREAT NEWS.
The Rules Committee finally replied:

>>>>
Dear Daniele,

It appears that the fuel line material you are planning to use is suitable.

You must have some sort of shielding over it especially in places where it
might be rubbed. Metal braided or helcoidal wire is not necessary.

With the fuel lines you have chosen do NOT use screw type hose clamps. If
you are not using threaded fittings please use hose clamps like those shown
in the attached photos.

Anyone interested in these photos, should send me an e-mail, and I'll send them in attach.

I just recieved an email exactly the same as that one. http://fsae.com/groupee_common/emoticons/icon_smile.gif

Yeah, but I don't get why they want us to use a hose clamp on a barbed fitting that is rated at 250psi. It seems a bit like overkill.

[V2-iacoto]

Hi guys, we found this one.
Do you think is it ok?!

V2, that's exactly the sort of clamp you need.

Where are people getting Tbolt clamps like the SAE rules committee suggested, or are most teams using press in fittings? All the Tbolt clamps I can find are 2-4" and our fuel lines are 1/2".

[BStoney]

If you are talking about the non-worm drive hose clamps, then simply get them from McMaster...

[Grant Mahler]

got it...the word miniature helps a lot.

WTF do you want to use 3/8 ID fuel line on an engine using less than 475cc/min?
If you are not going for the bogan dragcar look and want to lose weight & cost, machine up you own fitting to the same profile as OEM (eg Bosch remote fuel pressure reg), use 7.5mm EFI hose and the bolt& nut clamps speced by the rules and cover with heatshrink tubing.
It was good enough for the red lawnmower

Go to any REAL auto parts store (Uh-Oh Zone doesn't count) and askf or high pressure hose clamps, meant for fuel injection. Motormite sells a mixed box of them. I just donated a pack of 10 I bought from CarQuest. Cost $12.

I'm using a 1/2" line because thats what came stock, and I can't justify the costs associated with running all new fuel lines everywhere on the motor. In addition I would have to justify the time associated with putting new fittings on the fuel pump (or purchasing a new fuel pump, new injector fittings, and new filter fittings). But thank you for your opinion.

On a separate note, just because Cornell does something doesn't make it the right answer, or the best answer. I prefer to think for myself and come to my own conclusions, based on the experiences and opinions I can garner from people I know and books I read.

Thank you Mike Flitcraft - I will look in to that.

Good grief Mahler thats worse than calling me gay, "the red lawnmower" refers to the current World Champions!, I did the fuel system on RO4 and and last time I looked RMIT still use the same set-up. 7.5mm push-on hose and clamps are more reliable than any AN based system as they can't be accidently not tightened or suffer from damaged threads or sealing surfaces at critical times, like 5min before enduro
