Got a question for ya'll Chrysler / Jeep techs that work on Jeeps. The 98 Grand Cherokee we recently bought has a gas leak. It only leaks when you fill it up, and it seems to be coming from the top of the tank, right about where the lines go in. I have an exploded [bad term to use when talking about a gas leak, lol] diagram that that shows how the filter/regulator goes in the recess in the top of the tank. I'm thinking the leak is in that area, maybe a gasket under the fuel pump mounting plate or something, but the diagram doesn't show how that is mounted. It only shows the "O" rings on the filter/regulator. I know I'll have to drop the tank to find out for sure, but do ya'll know of anything I might need to look for that is common to leak on these vehicles? I was thinking that when I had the tank down I might as well put on a new filter/regulator. Good idea or not? Going to wait until it warms up before I pull the tank, so we are keeping it around 3/4 tank so it doesn't leak right now.
sounds like your gonna have to drop it no matter what. not a common issue that i know of. i have seen on a few cars where the filler outlet seam came apart. check that for sure..and the filler hose . other than that..gotta drop it to know for sure. any evap codes?
Dang, get a day off and it's 27 degrees at 9 AM. No way I'm gonna pull that tank in these temps. I'm ready for spring so I can get some stuff done!
Cant say I've had them for leaks up there. Done lots of failed fuel pumps. Maybe it had a pump put in and they messed up the seal??
That's what I'm thinking Darren. The exploded diagram I have doesn't show the seal or pump mount, only the filter/ regulator. I thought one of you techs that see these every day might give me a heads up on something that might be common on them so I could possibly get the seal or whatever ahead of time to minimize how long I'll have to have it down. Chances are, if I drop it on a Sat, it would have to sit until the next Sat before I could get a part and put it back together. And if wifey doesn't have her ride, she'll have to drive my pickup, and she'll fuss all week....
