Braided vs. nylon fuel line

[rcrahn]

Being in Cali (like me) you need to consider the additives in the crap gas here. There's been a great deal written about how these additives attack the inner linings of SS hose. So using a braided hose with rubber lining it will break down eventually. Hot Rod did an article in Jan 2011 on this.

One solution is to use hard lines as much as you can followed by a short section of braided that is teflon (conductive) lined. These hoses can be made custom at a local Parker fitting shop. That 's what I did. Not cheap but neither was my truck to build and I don't want to gum up my engine,smell gas or worse have a fire.

The other solution is the nylon lines and many are going this way too.

Here's a picture of our fuel lines with the hoses made for me. Using 3/8" SS hardline for supply and return to LQ9 6.0. Note the stripe on the SS braid that designates it is teflon lined. The line with the dash on it is a custom made center brake line allowing movement of the 14 bolt axle through the range os motion on bagged suspension. It is all the way up in this shot.

Do the russell an fittings still work with the teflon or j309R hoses? I started purchasing some of the fittings.

You should check with Russell on that.

After reading a great deal about this one conclusion I came to: Best to stick with the same supplier for both the hose and fittings. If you are making your own hoses mixing and matching hoses and fittings from different suppliers might create problems. Not always, but better to be safe than sorry.

That's why I always have my hoses made by a Parker shop.

I believe either hot rod or car craft had an extensive article on suppliers of fittings. Google for it.

Good luck
