A while back I took out my 38 gal rear tank so that I could revert to oe in order to re mount my spare underneath. Due my lack of diligence, the new tank came with the breather on the wrong side of the filler spout. Now, I can't fill the tank. Evidently the filler hose is getting pinched between the frame and bed. I have had the tank out twice, and purchased the correct hose with the metal U sleeve, the hose with a slight bend in it, and still I can't put gas in the tank. It is very annoying.
I believe I may revert to the 38 gal tank and simply delete the forward tank as well, unless someone has an answer.
Is the slight bend in the main fill neck hose being caused from the rubber tube being too long? Maybe shorten it and see if the bend goes away. So you got the wrong tank (none EEC versus the other) and that put the vent line on the other side.
"There are two differences between the tanks. Tanks with EEC have a hole in the top center of the tank. A rubber grommet and check valve are pressed into the hole. A line goes from the check valve along the inside of the passenger side frame rail to the engine compartment where it hooks up to a charcoal canister. Non-EEC tanks don't have this hole. The other difference is the nipple for the breather line that is located right next to the nipple for the filler hose is located 180 degrees opposite. If you are going from an EEC tankto a non-EEC tankyou must also change the fuelcap to a vented style. The EEC tanks are vented through the EEC system and use a sealed fuelcap. Non-EEC tanks vent through the fuelfiller cap. If you run a non-EEC tankand a sealed cap the minimum is you'll have fuelstarvation problems."
I've had metal filler necks with the vent line on both the left & right side of the filler tube. If you got the metal filler neck that lined up with you tank configuration, would that solve your problem?

Hey there. Thanks for the reply. I have had 2 hoses on this tank (filler hoses). One was a straight hose, cut to length. The other has a slight bend made in the hose. It too has been cut to length. Both hoses kinked where the hose passes between the frame and bottom of the bed. I can't help but wonder if the position of the spout on this tank is not correct for my truck. That must be the case because I can't get gas through the hose with either hose.
Do you have the metal piece that wraps around the hose?
The 38 gal tank AND a spare below it, will work, with home made spare tire bracket drop hdwr. Like all thread...But it will some low hanging fruit for sure. 2wd pavement only guy you should be ok.
Thank you ... wondered how low a 38 gallon tank would hang. I'd be OK with a 25 or maybe even 33 gallon '78 Bronco tank when needed. I don't have a spare under there, but I do have a hitch that I built that is about 6" below the 19 gallon tank.
I had to remove the metal U sleeve from my filler hose. I found that that was causing a crimp. Once removed, it filled without problem.
BTW, to each their own, and thank you for the photo of the spare below the 38 gal tank, but I prefer to have the oe 19 gal. tank with the spare below, or the 38 gal. tank and have the spare mounted in the bed.
There are a few points that other members should be aware of: 1. If you have a no ec tank and a ec spout, you can't simply buy a vented gas cap and be done with it. It will not fit. You have to change either the tank or the spout, or run the non ec tank with the ec spout without a vented cap. Period.
I wish I had known that before I bought a non ec tank.
