If I was going to have a piece submerged, I think I would give a chunk of it a good soak in gas with ethanol first from what I am seeing. If it goes soft, then I sure wouldn't trust it.

Specs say it'll handle just about any fuel situation. Even if pricey, you won't need much.
The liner will handle anything, the cover looks good but does not specifically list ethanol. I check the Weatherhead and its cover is not suitable for polar solvents. The Hypalon may be better.

You could also just use the nylon fuel line. It will be tough to get on but it will last forever.

The liner looks fine, its the covering that would worry me. It, CSM or hapalon is alcohol resistant all right, but rates poor to fair against petroleum products from what I found.

Spend some time on the internet doing searches for Walbro pumps and you might find a supplier that will have all the parts you need.

The short section of rubber fuel line I got from the company I used, was certified for in-tank use, all fuel.

I found some wiring for the Walbro pumps, but have a question on those. On this pigtail, is the terminal end what goes to your vehicle wiring harness, with the black and red wire going down into the tank to connect to the two screws on the pump, or is it the other way around, and the terminal connects to one on the pump?

My other option is that I have the complete vehicle wiring harness from the '96 cherokee that I got the motor from. I'll take a look at it and see if it has the wiring/ connection for the sending unit. I can then go to the JY and IIRC, the sending unit on the cherokees is real easy to get to, so I can pull the sending unit from one, and get the wiring harness off of the fuel pump. As long as that connection looks like it'll work with the Ford fuel pump I have, which just has two small screws on it, I can connect the cherokee wiring to the Ford pump.

For mine I got submersible gas line at NAPA auto parts. Normal fuel line is only coated on the inside with gas resistant coating, the submersible is coated inside and out, and is expensive.

Terminal goes to pump, wiring get's spliced into vehicle harness.

What is the model pump you have? Personally, I wouldn't be using those stud/nut terminals inside a tank that contains an explosive fluid.

I'm not sure of the brand, it was one I picked up off ebay. It looks like this-

I'm a little leery about using those studs also, but thats the only connection I have on it. Looking at the terminal connections I'm seeing for other pumps online, none of the connections look like they would work for mine because of the way those studs are placed. If you look at this pic of a '89 F150 sending unit, you can see the red/ black wires going down to the pump and they are just connected with a crimped connector.

And you guys aren't "leery" about having an electric motor, an open fuel gauge, and wires in the tank?? My 75 has the fuel gauge resistor just sittin in the open. No insulation, plastic cover, no nothing. And after 40 some years, no explosions.

Hasn't seemed to bother the automakers over the past twenty odd years. So I'll Alfred E. Neuman this one...

I'm curious what that orange nipple looking thing on the end of the return line is for. Does it open up under pressure? Is it even needed?

I'm making a new fuel pump also for 80 cj5. On my cross country trip recently, the intank pump assembly I bought from NOVAK failed electrically in the middle of nowhere. So I bought the same fuel sending unit as NOVAK uses, which just happens to be the stock sending unit. Like you I'm cutting off the tube and replacing with fuel pump. I'm using a delphi fe0114 pump pumps somewhere in the neighborhood of 66 psi. I drilled a small hole through the top of the fuel sending unit I think the hole is 17/64. I did research and ordered fiber and nylon washers off Amazon. The washers are shouldered washers. For the delphi fuel pump there is a oem connector, I forget the part number but if you buy the pump on amazon, it'll suggest the connector. The problem with the fuel pump I bought from Novak was the 12v power supply bolt was loose and the washers they used desintigrated and caused an electrical short. I have pics to post but am waiting on the day I pull the old pump out and replace with the new pump. What I plan on doing is using gasket sealant on the hole I drilled and then inserting the nylon shouldered washer then fiber washer and then bolt it together. I will post pics later tonight if you want to see what I've done so far.
