    Hey guys, I'm finishing up the install of the nitrous kit, the holley fuel pump is going in next. I want to upgrade my fuel lines since I have a lot of rubber hosing and last time at the track the inspector told me I got to have less than 12" anyway.

    I'm wondering what you guys recommend, is it safe to go with the stainless steel fuel lines like this one from summit?

    Or do I need to go with the braided flex lines like this one?

    thanks for the input

    If you plan on E85 your going to need stainless anyhow so you might as well do it all now.

    thats what i was thinking also. you will need to get ends for that stuff. you will also need some flexable hose to make some of the connections. i have alot of extra steelbraid with teflon liner that will with stand the e85. you will want to draw out your system then figure out what fittings you will need.

    hey Bryant, can we get the parts locally or do you want me to order them online?

    we can get most of them localy. they are cheaper on line by about 50%. i know that we can not get the stainless hard line you asked about localy.

    Why do you say you need Stainless with E85, I plan on running 1/2 aluminum hard line from the cell to regulator.

    i was under the impression that E85 and aluminum don't mix too well

    ive heard that e85 is and is not carosive to aluminum from all kinds of sorces. alot of them i really respect and still get answers that say yes or no. so i feel that it would be smart to minimize the alum. in the fuel system as much as possible to use e85

    As far as I knew E85 is too corrosive and requires stainless or teflon coated lines. The alcohol in E85 will corrode aluminum so they say. I do know that the gas pumps cant use aluminum nozzles to dispense the fuel so that would be enough for me not to use it.
    Funny this came up we were just discussing this at a course last week as were starting to get drivability issues with regular fuel that has more than 10% ethanol. Were getting samples as high as 25%. Good reason to buy super unleaded at 0% ethanol if you can afford it.

    I think E85 is often confused with the white death of Methanol. I was told E85 as a fuel grade meets ASTM standards and has corrosion inhibitors in it. I'm in my second year running the stuff, so far have not seen any issues with my aluminum fuel pumps, Carbs, fuel logs or fuel lines. I even run the stuff in my lawn mower, snow blower and weed wacker as well. Great for cleaning parts to. Not to say I won't have problems in the future, but i'm doing good for now and know a few others with no issues as well.

    most if not all of the aluminum stuff you mentioned is anodized. that protects it from the corrosion. i personaly have a aluminum fuel cell and fuel lines that run the lenght of the car. these have no coating and are my bigest concern for corrosion. i would love to run e85 but i would have to change my whole system. thats just not a viable option.

    Ethanol is no where near as corrosive as Methanol. I have used the E10 as required in Washington (the state) for the last 5 years or so. We run E10 all year long and I have had no problems with valves, tanks, lines, carbs hoses or anything else. Methanol will dissolve the hose in 12 hours or so of constant immersion. There was no anodized parts on any one of my three Mavericks.
