uch, 1991 - just filled up and it leaked a decent puddle at the fill station, moved it 50 ft to a safe location and no leak. Could it be the same deal? Stay tuned I guess. anyone have a solid tank for a 3fe model 91? Just in case....
Pretty sure all of the tanks for the '91-'97 are the same. If you have rust issues up there, now is the time to consider a new filler neck and skid plate along with all new gaskets and hoses(maybe not the actual hard fuel lines, mine were OK, but for sure all of the rubber bits.)no text in reply BILT4ME, any insight?
Nice that your wrote it up. No leaks today, despite a full tank and spirited (3fe) driving . When it did leak, it leaked clean gas from the middle of the truck, but a smaller puddle of filth/gas mix from near the filler tube, about 6 inches in. The attendant might of overfilled and it presented an issue. Time to start collecting all the parts.
It's unlikely you have a leak in the tank or filler neck if it builds pressure in the tank. Mine didn't have the whoosh until I patched the old filler neck and then I discovered I needed a new charcoal can after I did. Everything is just peachy now that all of that stuff has been replaced.Chasing this issue too. I drove from seattle to san fran and back this last week. Twice i had gas overflow from the tank to make a sizeable (couple cups) puddle on the ground at the driver rear corner of the truck, but that was out of over 10 fill ups (til the pump clicked).
I'm thinking its actually charcoal canister related? going to try that and see if its clogged or the issue. I'm getting high pressures in the tank when hot out which makes me think the tank isnt venting while filling up and causing a bubble to push out or something funky. No idea where else it cou.
My same thoughts. If it's building pressure it's not a crack or leak so must be a venting issue causing the overflow.It's unlikely you have a leak in the tank or filler neck if it builds pressure in the tank.

The good news is that is the easiest part of the whole job too!My same thoughts. If it's building pressure it's not a crack or leak so must be a venting issue causing the overflow.

Also what i've heard. Debating trying to take it apart and clean and replace charcoal as some have vs the autozone special.Mine is also building pressure, related to a clogged check valve in the charcoal canister. The goal is to get this fixed asap as to avoid the cracked tank issue.
So, I am not sure on the details of your trip, but I just did some quick math and it looks like if you drove the 1800 or so miles for the round trip from Seattle to San Fran and you bought 250 gallons of gas, you were only getting 7.2 mpg which is really low. Didn't you just rebuild the whole top end of the motor? I get twice that on my rig which I did the same work to. I am not trying to be nosy, I was just thinking you might have something else going on too.Chasing this issue too. I drove from seattle to san fran and back this last week.

That's more like it!Haha I was filling up with 1/2+ tanks a few times to be on the safe side and was doing a lot of detouring. Without the rooftop tent i was averaging 15-16mpg. With the RTT i was getting 10-14 depending on speed/passes/etc.
