Yea your right about the mountain. Just didnt know the exact set up and if it was right above the tank if they could fall in there or if I could drill into the tank. Falling on the floor or anywhere else I dont care. But I do appreciater your help and feel pretty confident now. Thanks

They should just fall on top of the tank where the FSU is housed, prob into the little dip. Mine has been left loose since it was originally taken off.

I did just that and now I have a pin size hole in the tank. Going to put tank patch over it I guess.

Also the original poster asked about changing out the fuel hoses going to the sending unit. Can this be done easily? Do I need to drop anything, remove anying or can I just snake the hoses around to get them to their start and end locations.

I am jumping into this almost a year later, but I too have problems with my fuel gauge. It reads full all the time, so I believe I am getting electricity to the gauge. Could the float be stuck on the sensor? This has happened to me on other cars. Where is the access to the sensor on the tank - this would be on a 1989 GW. I am also having trouble filling the tank - I have to hold the pump handle and take about a minute per gallon or the automatic function of the pump kicks in.

Merry Christmas!!

Drop the tank to get to the sending unit. There is no access plate.

While you have it dropped, inspect the fill hose and the fill vent hose for kinks in either one.

Probably should have started another thread of your own.

Merry Christmas

Not true. You do not have to drop the tank. Later Grand Wagoneers have an access point for the fuel sending unit/pickup. Take out the rear seat and fold back the carpet. There will be a circular plate with several screws holding it in. Not sure what year that started but my '88 has the access plate. Much, much easier than dropping the fuel tank. Though you may have to drop it anyways if you are having issues with a kinked hose.

GPCL-

Yup, I thought that was the case. Although the weather was cooperative yesterday and I could have done some things on the GW outside, I spent the day in the garage. Last summer I grabbed the doors off an '86 GW at a "ewe-pullet" and decided it was time to pull them in from the snowbank and strip them. Things went fine until I discovered that one of the window motors was fried! I got two of the doors pretty well stripped though and parts into a storage tub... Gas tank is next!!

Merry Christmas

Do not drop your tank. Find the access panel and go in that way. Replace your fuel sending unit. The plastic nut holding it on was a ***** for me to take off but a screwdriver and rubber mallet did the trick.

Little Green,

Great! Thanks for the info! I am almost wondering if the float is stuck in the full position? I am getting a signal from the sender, just reads full all of the time...

Merry Christmas

Good to know. The newest one I've owned is a '79. I should know better than to make a statement as if all FSJs are the same as older ones. Jeep built them after all.

I wonder if that access point was made possible after tanks were moved off center more than the '79 and older.

Just to update my own thread: I replaced the FSU and removed the dash cluster. After a lot of electrical spray the fuel gauge works. Had to replace the mech fuel pump and starter module (80s style computer thing as I was told) and running awesome after shipping the girl to El Paso. I really wish I could have seen some faces staring at her as she moved cross country.
