What do you think caused this?

I put the fuel tank back in my B2 and its leaking AGAIN from the sender o ring.

Same place it leaked after i installed the tank the first time.

That time i blamed it on the fact i reused the old (but still new) O ring.

This time the o ring is new from bronco graveyard.

I got it togther roughly a week ago and ive been driving it all over hell (even filled the tank) and last night i went to run up to subway and smelled gas when i parked. By how much it was dripping i figured it was a line.

Got my food and went back home, found out it dont leak unless i hit the brakes and it sloshes.

O ring, sender, tank, and lock ring are new. Just tired of pulling the tank every week.

Any idea?

Was the lock ring difficult to spin around when you installed it? It should be. Sometimes the little tabs get bent and don't press the unit down against the o-ring like they should. They can be tweaked with some hammer work. Of course you will have to pull the tank again, but you are driving it and can run most of the gas out of it.

Pull the bed this time?

You probably know this, but it’s important to lubricate the o-ring with silicone grease.

They freaking suck.

I fought a similar issue on my '85, most new locking rings are too small to really engage the tabs. So they hold for awhile, shift and pop loose.

I used a LILAND ILO04 from Rockauto. I just put a pump in it over the winter and even the new ring that came with the pump was junk and I reused the Liland I bought the last year to fix the ongoing issue locking rings not holding.

I just ordered another lockring and gasket from napa. Ill try it if it acts up again ill try the liland.

If the ring came loose im wondering if i could reach in through the wheelwell with a long....something....and tap it back tight. I wondered if maybe thats what happend.

I couldn't if I could even reach it.

I have to very carefully and slowly work it around with a chisel on all the tabs. Too much on one tab and it will get out of center and pop out.

Oh sorry.

At the dealership we had the tool to turn the lock ring, at home I use a big pair of channel locks and a lot of care. Maybe try that instead of using a chisel to avoid possibly distorting the ring. Removing gas tanks always sucks.

This one does go in and come out very easy...like i can almost slide it around by hand. But every other one ive messed with has been rusty both the ring and tank. So i figured it was easy cause it was new.

Oh sorry.

lol no problem.

I always have just used a flathead and a hammer...never had one leak, So i dont know...guess ill be more careful with this one

 

[SenorNoob]

Should definitely be tighter than that.

Yeah, mine has always been a brawl.

Good to know.

This one went 3/4 way by hand then one or two light pecks with a claw hammer

 

[franklin2]

A little pliers and hammer work and you can make it tighter.

For seven years I worked at a gas tank manufacturer that did tanks for the Honda Civic, Nissan SUVs/trucks, Chrysler minivans, Jeep Cherokee, Corvette/XLR, Ford GT, Acura TLX, Mazda, and even the Karma tanks. So I can tell you unequivocally that it is absolutely okay to use a hammer and a flathead screwdriver to close the locking ring into the encapsulated ring if you do not have access to the removal tool. From the factory we lubed the o-rings but never greased them.

But I also acknowledge that the BII tank may be a different breed.
