Fuel line choices

[GetOwnedVette]

Last thing to order this week concerning my fuel system are the lines and fittings. Been reading up on the fuel lines and systems people have come up for external pump setups and what not and noticed a fair ammt of mention with e85 eating up some of the rubber in peoples systems. Not just gunk from the tanks.

My question is why are people not just eliminating this "gunk" problem fear from the lines and going with some Methanol rated socketless fitting hose like : Aeroquip FCN1020 - Aeroquip AQP Socketless Hose - Overview - SummitRacing.com

Its a bit pricey yea but so easy and looks great, 10 feet is still under $50. My old man runs the stuff on everything I will admit when done clean I think it looks really badass also. But after showing it to me I was more ready to do my setup this way. Seems kinda fail safe.

Has there been an overall consensus on what line to run with E-85 that I missed via search?

I've had that stuff on my car for years and have not had any issues with it. Recent swich too, I will see how it goes. I don't expect any issue. Some times we worry too much. If it does begin to be an issue you will see increased duty cycle as the injectors fight to keep the air fuel ratio correct. If you let it get too far out of hand you will notice the lean air fuel ratios or other obvious signs of lack of fuel. When doing new things you have to keep tabs on everything.

I went with jegs pro flo 200 braided hose. pretty cheap for -10, and I have a funnel-filter w/ a 60 micron SS element that filters before fuel enters my cell/fuel jug to keep crap out of there.

Also when the car will sit for awhile I'll be draining the e85 out and putting 91 in just to get rid of the ethanol in the lines.

Not to thread jack but those that have installed replacement lines, what length worked for you? I see it in 15 and 20 foot lengths. Thanks.

15 worked fine because I Y'd into 2 smaller lines (-10 into a Y of dual -8 about 8" from the rails)

Thats what im on to figuring out now....size and length of each section I buy...how much 8 how much 10 etc...

I believe we bought 15' of -10 and 6' of -8. We had some-10 leftover, but not too much. We also were running a fuel cell in the trunk, so the lines went through the trunk floor directly to the pump. We used a foot and half-ish for the rollover valve on the cell, and with my new filter I got, we're going to relocate the current lines and start the Y lower down, more towards the alt bracket mount, so we'll need another 1-2ft there.

Mind you my -10 filter is about 6" long (25 micron SS element from Kinsler, the only people to make an element that small in SS) which mounts right into the Y, so that lowered the location of it so that it'll fit securely in the engine bay.

I'd say 15ft of -10, and 3ft of -8 would be fine. You need to factor in how long your filters are, how long your pump is, and how much length the fittings themselves will take up. The pump and filter take up roughly a foot in itself, to give you an idea.

Just as a side note... I was just checking my database, and I have over 150 customers using E85. Not a single person has reported any type of fuel line problems (to me anyway). That history is only about 3 years old though, but so far so good.

I think a lot of this "the world is going to end if you don't completely convert to SS lines and spends tons of money of parts" ideology is part founded in truth, and part in speculation and the 'ol "well this happened to my friend's cousin's sister's boyfriend...so its true".

IMO, run the stock lines unless you plan on going faster than high 10s.
