Fuel Tank Sensor going bad



nope.. I went to parts store and none had them or even sold them.. I think they come with one when you buy a pump.. Look around not for sure yet.
 
You really should get a new oring for it not rtv you want your pressure to be there in the fuel tank.
 
Pull the fuel relay.
Crank car for a bit.
Push the little nipple on the fuel rail some.
Disconnected the battery.
Pull all the carpet out.
Take off cover.
Pull all the fuel lines off.
Disconnect sensors.
Use needle noses and remove the ring, or bolts depending on car.
Pull out pump remove old sensor put on the new.
Put everything back together, make sure you get the seal on the right spot and the pump is tight in place not moving around so the seal is there.
Put back in the relay and connect battery fire up the car.

Don't want a full tank when working on this so try and have around halfish I was fine with that.

Took me 30 min to do. You need to be strong with the pump to push it back in place if your pump is held in by a snap ring, I had to hammer it down in place.. If its bolted in, from what I've heard tightening the bolts pushes the pump in and seal it easily.
 


Just watch that once get a idea what you are doing follow the steps I showed you and then you will be on your way just fine. Don't rush and take your time. MAKE SURE THE SEAL IS TIGHT. It sucks having to take it all out again, just post if you have questions.

O ring goes between sensor assembly and tank it's more like a large rubber grommet than an o ring
 


Yes some cars "seals" are like that.. Like I stated my system contained a large o ring, like posted in your first post.


When you get the new sensor they send you a new seal like that, most don't need replaced though.
 
JAllegar - did your fix with the pencil eraser work? I am curious as I have a similar issue with my pump/sending unit.

FYI - the unit was a cinch to take out. After opening the access panel I used needle nose pliers to pinch the locking ring and it popped right out from under the locking tabs. The unit came out easily enough. However, in my case the dip-sh*t I bought this car from had taken it out once before. He obviously did not put it together correctly as the rubber ring that seals the tank was at the bottom of the unit hanging on the float arm. I was going to deal with the sending unit later on but when filling up with gas I was flagged down by another patron screaming I was draining gas all over the place. I looked under the car and sure enough fuel was barfing everywhere.....including my hot exhaust pipes. I managed to shut down the gas station.

Long and short, even though you have to really muscle that sending unit back into the tank with the locking ring...do it! The guy before me did not and I could have had a fireball on the 6 o'clock news.
 
I used some silicone lube on the o-ring to help it slide down and seat easier... worked like a charm. Then connected my battery back up and my frick'n radio was locked. Thanks to this site I found the info I needed to unlock it. The fuel level sensor I got had the wrong plug-in for the fuel pump so I had to pop the pins out of the original sensor plug and put it on the new one...still took less than 30 minutes for the whole job!
