Running off boat tank again with no problem. The tank is definitely full. The shower head could make sense.. I may just get a 50 gallon tank in the bed and run a line to the pumpTank selector valve? These are notorious for failing.
Water separator? Mine is near the brake booster. Not sure if your truck came with one. They are known to fail/leak.
Shower head(s)? These are the fuel pickup ends in the tanks. They can fall apart, or off, and you'll be sucking air if your fuel is starting to get low. Add more fuel and then you'll know.
Is the fuel tank selector valve still connected?
Is there a water separator present?
Sizzle is an excellent descriptor for the sound lolPlug the Block heater in, you should here is sizzle with in 30 seconds. With thee Coolant and Block warm the Oil will warm quicker.
If it does not sizzle, it could be corrosion where the Cord plugs into the Block Heater.Sizzle is an excellent descriptor for the sound lol
Don't try to purge the water separator. If it wasn't leaking before then it likely will if you mess with it. Bypass it. At least until you isolate your problem. My bet is on the fuel tank selector. That was my problem. I've been running on just the front tank since then. I gotta deal with that some day.Correct, Supply is 3/8" and Return is 5/16" fuel line.
If your year truck has the factory Water separator next to the Brake Booster, and has not been by passed. You can use a double Barb 3/8 fitting and connect the 2 hoses together.

I think you’re right on the money, I looked at it and it looks like it never been replaced, covered in mud. We will find out here shortlyDon't try to purge the water separator.

your best option of deleting the selector valve is to pick one of the good tanks, and run brand new rubber fuel line from the pickup to the lift pump, and from the return tee back to the tank. this will shore up hopefully any air problems. you would be better in the long run if you dropped the desired tank and inspected the pickup and for sludge.I’m trying to fix the truck and stick on my ranch to use a couple times a year running to the blinds/ fill feeders. One tank will be fine for that
