When the Jeep is running or turned off, my GAS needle is slammed past full! Just wondered if anyone had come across this before and what to check, to correct it?

 

So your saying no matter how much fuel is in the tank your needle is past full? It would be your sending unit is stuck. There is a float on it and sometimes when they are old its just gets stuck. Pull pump assembly out and look at it.

 

Yeah no matter what its way past full, Ill have to pull it and take a look at it i guess, hopefully its just stuck!

Thnaks..

 

It's most definitely the sending unit. I had the same thing on mine. You'll have to drop your tank to get to it so be ready for some work.

 

Well not really. I dont have to drop mine. What year is your jeep? The newer ones are a pain but the older ones you just climb under and pull it out

 

Mine's a 99 and I had to drop the tank. If you don't have too then that makes it WAY easier for you to change it out.

 

Ya it depends on the year it is. I had an 88 and didnt have to drop it and in my 91 I dont have to either. Just crawl under and take a look. So no rdplz is yours on the top of the tank?

 

hey, i wish my gas tank was always full. it just seems to be constantly empty :-/

 

Darn....you read my mind

 

But make sure you get the right year sending unit. I had one from my old 88 that I put in my 91 and it read backwards. lol

 

that one was too good to miss. glad it was appreciated

 

well, on the bright side you must have some great fuel economy

 

Yeah, and it sucks having to get to it. A big thanks to Chrysler for making a stupid design for the sending unit!

 

My is actually a later year, 88! So it shouldnt be to hard to pull out. My needles a quarter inch pass full, now thats MPG baby..

 

Ya I would diconnect youe battery and then relieve the pressure in the lines and then just take to 2 hoses off and spin the lock ring and pull it out. Just dont go crazy you will have to move it around due to the float and sending unit. Its not hard you can do it.
