these AN fittings are insane!!

[rtm]

trying to run an INEXPENSIVE fuel line system from my cell to my carb and back.
just spent an hour on the phone w/ a guy from jegs,
I already have my fuel cell ,pump, and regulator (and a 100 micron prefilter )
all I need is fittings to run 1/2" aluminum hard line w/flexible stuff between tank/ components.
and I need another filter before the regulator.
anyone have inexpensive ideas?
this guy had me @ $350.00 for just a feed line.

Yes, I looked at them for a fuel injected street rod project. I just went with steel line. Bulged the ends with the first step of my double flare tool. Regular fuel injection hose and clamps. NAPA looked up a 3/8" filter for me. Pretty much like some Chrysler systems i've seen. Don't know about race applications, but it looks like it will work for me.

Check Summit Racing, they have kits that include everything and are cheaper then building your own...hope this helps!

[rtm]

alrighty kids, I've ordered parts from summit AND jegs for this phase of my build, I'll try to document part #s and prices here.
maybe I can save someone else some economic stress by posting what I end up with, and what it costs.
there are too many ways to put a fuel system together for it to be a true guideline, but hopefully my mistakes/successes will help others.

I agree this AN stuff is way more expensive than I expected it to be; a couple of months ago I bought everything to build the fuel system for my race car and it was in the $550-600 range. That included a Holley "blue" pump and all the line(1/2" aluminum and -8 braided), filter, all the fittings & adapters and a dual feed line for the Holley with built in gauge. I tried to economize as best I could by choosing the Jeg's "house brand" instead of a name brand(Aeroquip, etc.) but it still cost about double what I was expecting. OUCH.

the main problem w/ the "store brand package kits", although they're relatively inexspensive, is that they kind of limit what you can expect/ achieve
both summit and jegs offer them ,and claim they suport up to 500 or 600 HP
however I found the line sizes (dia) to be rather smallish on one, and the other didn't include a regulator. (I thinkit stated in the description that it wasn't needed because the pump pressure was preset.)
any of the "better" systems I've seen on cars like the one I'm trying to build, utilized a good,name brand pump/regulator.
maybe I'm niave for not trusting the generic packages, but with all the money I have spent on my engine already, I'd hate to cause something stupid (like a lean fuel condition) to ruin it.
I guess I should expect to pay for "quality", however , I know for a fact that these AN fittings are all made offshore somewhere, and the materials they contain are far from "rare"
maybe I should quit bitching, and start a manufacturing facility of my own, after all ,it is the american way

""Also known as AN fittings, these fittings are made to exact AS (formerly AN)
specifications. Not only are these fittings manufactured to tighter tolerances than
other 37° flared fittings, the nut/tube ends have 3A and 3B threads, which adhere
to higher tolerances than all other nut/tube end threads. They meet ASTM A380 and
SAE AS4841. Fittings are made of forged or bar stock Type 304 stainless steel and are
furnished as a body only; nuts and sleeves are sold separately. Use with water, air, oil,
and hydraulic fluid. Not rated for sterilization or vacuum. Pipe connections are ANPT,
which are compatible with NPT. Nut/tube ends have UNJF straight screw threads.""

To clarify, I didn't buy a "package" from Jeg's; I designed the system from scratch, right down to each fitting and end and only ordered the pieces I knew I'd need. The only thing I'm going to have left over is about 10ft of the 1/2" aluminum line, and that will no doubt end up on my brother's car. i stuck to the "Jeg's" branded stuff so it would all be the same, but it only saved 10-15% off the price of the equivalent Aeroquip parts.

[v8astregt]

When I did my fittings way back when, and I got a refresher last week when I changed my lines to go to a double pumper, I remembered that I used both Aeroquip and XRP. The XRP fitting took like 45 minutes, cussing, and a few pierced fingers to get a good fitting. Meanwhile, a comparable Aeroquip fitting took me 5 minutes, and was pain free.

So as far as fittings go, I will always pay top dollar for these. There is a difference, at least in my opinion.

I'll get to revisit all this again soon. I want to go from my single 3/8 line, to a 1/2" supply line, with a return regulator, and return line, plus a sump added to my tank.

my "package" post was in response to meangreens post
although I am very interested in what you have spence.
shred, are the push locks NHRA legal?

AN fittings are indeed 37 degree fittings,
however,from what I can see on this site all the "bends" are the restrictive type you would find in traditional brass NPT fittings.
everything I have researched to date recommends avoiding these types of restrictive fittings,
the straight ones may be fine though.
Agian, I'm only going by what I've read,or heard, from other sources.

[Sirshredalot]

As far as i know, Push-lok hose is NHRA legal....The rule book says less than 6" rubber/flexible line....dunno what that includes...but Ive seen it run on 10 sec LS cars and they passed tech.

Its good to 200psi and 300 degrees if you get the good stuff. and its less $$$ than braided...and less painful(electrical tape and a cut-off wheel is your friend).
Just be carefule....alot of the stuff on the market is NOT compatible with FUEL....The AEROQUIP and RUSSELL are good.

just resd an article in one of the mags and they warned about buying the cheap offshore fuel lines and fittings.. the insides of the braided lines rot pretty quickly and the fittings are cheaply made and the centers dont line up well and they leak pretty quickly. i always buy a brand like russell or aeroquip. costs more and hopefully lasts longer. art

[meangreen73vega]

Ya it's a bit more than I remember...I just dug out my reciept for my fuel system...$1400.00 but that's complete from a 5gallon tank, Mallory fuel pump with regulator, Mallory filter, 16 feet of push lock hose, and all the fittings including a carb kit dual inlet....oh almost forgot........... got a NOS sniper 100-150HP with it
