No problem. I purchased my fuel line/filter kit from Amazon, it was around $40.
The Edelbrock p/n is 8131.

This is a good thread. There are lots of people out there new too their trucks that shouldnt take this thread lightly.

I've noticed over the past decade that most of the rubber sold just don't hold up well(even most tires). Between the ethanol in the fuel and cheap low quality rubber it just gets worse. My luck has been the rubber lines deteriorating from the inside and clogging fliters. thats Not very noticeable from the outside till you look at the filters lol.

Of course all these trucks need the rubber line just keep a good eye on them.

Nobody wants a fire.
Take a quote from
Mr. Red eyed Grumpy cat
It will burn down with the lazy mans rubber fuel lines.

I agree, this is a good thread. I use Eaton Weatherhead H101 series hose. It is compatible with air, fuel, oil, coolant. Has a nitrile inner tube with 1 fiber braid and a neoprene cover. I used it on the gas tank to hard line connection under the truck, the hard line to fuel pump connection, and I also used it for my heater hoses. It will withstand up to 350 psi and comes in 1/4 3/8 1/2 5/8 and 3/4 ID.

" Just a question: What are you anti-rubber guys using for areas where the fuel line needs to flex. "

A short piece of fuel rated rubber hose from frame to pump, and that is it.

==> clean gas tank, hard line, inline filter with short piece of hose at each end, fuel pump, hard line, and sithered bronze filter at carb inlet.

Bending & flaring my own lines was one of the very first automotive skills I learned. Had to. My first car was a free '71 Pontiac LeMans sport and the hard lines were shot.

I dont use the big chain auto store hose , bosch/deutz outer braided injection hose , wont kink & holds up on E15 & modern diesel fuels. Not extreme pressure( about 30 psi)Most Napa etc. Fuel lines turn to mush fairly quick. Have over 1500 diesel & gas engines in our equiptment fleet , & it been serving us well for years.

Go to post #21 and #30 in the attached. I used 3/8" brake line and a $30 tube bender and made my own.

Don't know where to get something like that. So that can be cut and clamped on the hard line from frame to mechanical pump, and clamping the outer braid does not cause problems?

We usually get in bulk , but same fabric covered fuel line/hose can be purchased from VW or other German /Euro automotive suppliers. Vw,Mercedes, etc. Use this style of line.& std worm gear clamps are ok , but the fuel injection clamps have no gap. The covering acts like a chinese finger trap once its pushed on its tuff to pull off ,used it years ago on my s10 pump in tank connections that was 77,000 miles ago & counting.

I suppose without the exact specs or part number it would not be possible for a hobbyist to get. I've done quite a bit of online research on this subject. Hours and hours spread over weeks. Unless you "just know" from experience (in my opinion) choosing the right thing and sourcing something like that is utterly overwhelming. And in the end, there would be no way to tell if it is the good stuff, without waiting and observing over a period of years.

There is quite a knowledge gap in this hobby, where experienced people know stuff they don't even realize is very obscure and difficult for less experienced people. So by the time a newbie reads to the end of this thread, all they can really do is shrug and go up to O'Reilly and get a rubber hose and hope for the best.

I totally agree , what may be common for one person ,may be foreign to another. . Thats the great thing about forums like this one. We all can learn from one another.
