I suspect it as a fuel issue so far as when I put my fuel pressure test kit on and didn’t get any fuel spraying out on the Schrader valve either while connecting or disconnecting. Just air hissing.

1986 5.0l 302 original unmolested

I am not a mechanic. And am just speculating but I think it maybe the sendingunit assembly. My fuel gauge works and I can hear the in line fuel pump trying to do something,

my next order of business is im gunna replace the canister fuel filter which is in unknown status. That thing is a ************. Any tips on how to loosen it without taking the whole assembly out?

Truck has the original fuel pump and I suspect OG one in the tank. The filter between in line pump and engine was replaced by me when I first got the truck

I have done this with the canister in the truck about 30 years ago. I can tell you, taking two bolts out and some fuel lines made this much easier to do than working around the transfer case shield to get the seal to seat properly.

If you remove the skid plate (4 bolts) you can get on that filter pretty easily with a strap wrench and get it loose. also clean the crap off the skid plate while you're at it. That way you don't have to undo the fuel lines. 6 one way, half dozen another really i suppose.

I tried that but I couldn’t get it to unscrew. It was so tight. Even in the vise when I took it off it took quite a bit of effort to get it to give.

I used one of these i believe to get mine loose...and from best i could tell, it had NEVER been changed, it was absolutely gross. I do have some rubber strap wrenches too, but i really don't recall which I used. The fuel filter on my daily driver is in a similar spot as well.

yeah I went and bought the right size one of those. I am gunna replace the whole assembly with that one I showed you off Amazon. Coming in the mail today. I also went ahead and bought a in-line fuel pump as well made by Carter. I am kind of hesitant to take the Motorcraft one out as it does turn on and work but I just feel like it may be on its way out, just due to the age of it. Its held on partially by a ziptie too from previous owner

heres the filter set up I am gunna replace the plastic Ford reservoir with:

and here's the in line FP I got. Guess I would have to splice it in too. All this stuff is new to me so I am learning as I go.

and I also got a new pressure regulator as well as a new IAC valve both made by Standard

What kind of hose line do yall recommend I use? I am trying to figure out should I stay with 5/16 or go 3/8. 3/8 would be easier since the replacement sending unit connector goes from 5/16 to 18" of 3/8 on outlet...

Would I have to replace all the hoses to the engine if I went with 3/8 to the fuel filter reservoir? I am confused on how/if fuel pressure works in the hose as it leads up to the engine.. 3/8 is much larger than the latter. Just don't want to create any problems

Are you talking about removing the entire hard line and replacing it with hose from the tank to the filter? If so, i'd leave the hard line and just use short pieces of hose to make the connections, but make sure you put a flare on the end of the hard line so the hose has something to tighten up against so it don't slip off.

Oh yeah I’ve got the flare stuff figured out. I’m just tryna to understand the differences in hose dimensions if any. I have to replace the hard lines because 1. I broke the connector going to the sending unit and 2. I’m plumbing in a new fuel filter assembly that only has barbs

You can get some NPT to Flare adapters for the filter if you wanted to keep it all hard line, and since its fuel line you can do single flare...just a thought.

I bought some nylon lines from JBG that fit reasonably well for my conversion to a late mode fuel system.

the flare side attaches to the quick disconnect?

Right now I am on the track of running two 3/8 hoses from tank to the first filter reservoir housing then from that point on going 5/16 all the way to engine. It would just be easier that way. on the 5/16 side of the filter housing (outlet) I am trying to figure out how I can hook up to the 5/16 quick disconnect hard line thats already there? Any ideas? Hope that made sense

What brand pump so I can avoid? I’m thinking just getting a new tank saw one on oreillys for 155 bucks 33 gallons. Bronco graveyard didn’t have the right gallon tank

I dont know about quick disconnect , im sure someone somewhere makes it. Maybe Aeroquip, they make tons of that stuff. I was just saying if you wanted to buy some tubing and build your own hard line to the filter, that way you wouldnt ever have to worry about the hose bursting or anything like that. Also someone mentioned the poly line that modern cars use, they connect with compression fittings.

Hose sounds easier, but not if you do it correctly, keep in mind you will need to put several hose clamp holders along the way to keep that hose from sagging and wiggling around under there. I'd probably put one every foot. The metal line could just snap back in the original holders without having to use all those hose hangers.

I used hose on my race car when i first plumbed it for fuel (Hydraulic hose), i put a hanging clamp about every 2 foot and i looked under it one day and it was just sagging and flopping around, i went back and doubled up on the clamps, then eventually just pulled it all out and put in a hard line and didn't have to worry about it anymore.

Good advise. So hard line, where do I get that? Is it custom molded like brake lines? The current lines I have are all hard line plastic but I am having to replace at least one connector as I snapped it off when removing the gas tank. That’s what has brought me to this point.

on the sagging issue I was already planning of getting those mounted hose clamp things. The framesdrilled out for me to install more along the fuel line route.

I used these dudes for the nylon line. Bought some small AL spacers and spaced them off the frame rail where appropriate.
