New member to the forum.Can anyone give me any suggestions on how to get the fuel and electrical connections disconnected on the rear tank of a 1986 F150 without taking the bed off? I have taken everything else loose but there is not enough room betwen the bed and frame to get to those connections. Any help would be greatly appreciated.

You don't have to take it off - loosen the bolts & lift the bed a few inches in-place. Or lower the tank slightly. Or both.

But taking the bed off makes the job MUCH easier, and gives you the opportunity to WASH the tanks & frame.

Yeah I've taken the bed off before. I replaced both in-tank fuel pumps at the same time while I had the bed off. I bought the truck new in '86 an now I am restoring it. I am taking the tanks out to inspect to see if I need to replace them. I was just looking for an easier way to remove the rear tank.

Ok I've got the tank out now but I've got 35 year old fuel lines. Has anyone updated the OEM fuel lines from Ford with a more practical fuel line from tank to engine and if so please give me all info regarding aftermarket part numbers. All help would be greatly appreciated!

Steve83

There are no aftermarket OR original part numbers for that fuel line. What's impractical about the ones on it? Post pics.

Where do you find complete replacement fuel lines for that model truck?

Nylon,Quick connect?

I believe Steve 83, that you answered your question about what's impractical about the fuel lines on the '86. No OE or aftermarket part numbers for REPLACEMENT PARTS!

Only in a junkyard. And there were SEVERAL distinct fuel line configurations for that model truck, based on engine & other options. So until you specify what YOUR TRUCK has, no one can really help you.Is that what it has now, or what you want to change it to? Put ALL the truck's details into your signature so we know what you're talking about, as this page explains:

It's 36 YEARS OLD. There aren't enough of them still on the road for any company to make money building parts specific to them. If you think there's a market, YOU build & sell those fuel lines. But there were so many variations, for so few years, so long ago, that I don't think you'd ever sell even 1 set. Prove me wrong.

For most of them, the fuel lines were galvanized steel tube with rubber hose clamped on here & there. The lengths & bends varied by year, engine, wheelbase, tank configuration, & probably other factors. So buy the components, cut & bend them the way you need, and change them out. The EFI trucks were more complicated & expensive because they had hard nylon with quick connects, and there was a return line built the same way but a different size, so they're even more-specific to the truck's configuration. You can buy a kit with the line & fittings, but you have to assemble the line to the connectors (which isn't hard) and bend the line (using a heat gun) to the shape you need. Either way, there's no PN for the line you remove OR for the line you build.
