maddzz1 Posted April 1, 2010 Share Posted April 1, 2010 Not sure on price but alot of the aftermarket tanks don't have the pan inside the tank. Not sure if the pan is to keep the fuel pump from overheating or if it has other purpose. Link to comment Share on other sites More sharing options...

mjtjnj Posted April 1, 2010 Share Posted April 1, 2010 I got mine at rockauto.com, not a bad deal. Not to hijack, but I put my fuel pump in and am putting the tank back in this weekend. Is there a "wrong" way to put the pump/float apparatus in? The float goes in that pan? I just popped it in there, will the float just end up where it belongs, or did I need to take special care? :eek: Link to comment Share on other sites More sharing options...

green_miner Posted April 1, 2010 Share Posted April 1, 2010 mine is leaking as well, anyone know of any good repairs? I've heard of a coating you can put inside the tank but I do not recall what it is called. Link to comment Share on other sites More sharing options...
knever3 Posted April 1, 2010 Share Posted April 1, 2010 mine is leaking as well, anyone know of any good repairs? I've heard of a coating you can put inside the tank but I do not recall what it is called. It's not cost effective to fix a tank for our Jeep. I called Gas Tank Renu locally and they said it starts at around $300! They said they fix tanks that can't be bought aftermarket anymore. I thought it would be cheap, boy was I wrong. I wouldn't fix it by pouring something in there because I feel my injectors are worth more than the gas tank. I bought mine off ebay for $119 I think, it has the interior baffle but the pump doesn't seat into a premade hole in the new tank, it just sits there. I haven't had any problem with the tank so that's my recommendation. Link to comment Share on other sites More sharing options...
dasbrick Posted April 2, 2010 Share Posted April 2, 2010 $300 bucks I will buy a aftermarket fuel pump sender and a fuel cell. now thats an idea..... Link to comment Share on other sites More sharing options...
Wildman Posted April 2, 2010 Share Posted April 2, 2010 The "Pan" in the tank acts as a reservoir, there are no 'baffles' in the MJ tank, and to keep the pump supplied, the pan does this as the gas is sloshing around in there. The pan is needed for the EFI. Also, the return line drop into the pan. When installing the sending unit, you want to make sure the float arm does not become trapped with the pan, other wise, the sender unit will not function. I think your best bet is RayBucks, plus you can pick up, right Bad_MJ??? As I told you, Por-15 makes a gas tank kit - http://www.stoprust.net/POR-15-Fuel-Tan ... -p-50.html Me.......I would just buy a new tank, and get another 20 years out of it........after coating it with This product ;) Link to comment Share on other sites More sharing options...
jimoshel Posted April 2, 2010 Share Posted April 2, 2010 :agree: Also I've found that by dropping the drive shaft I can remove, replace the fuel pump without dropping the tank. Most of the tank sealers on the market are primarily for new tank use. Not sealing older, leaking tanks. And for the cost and trouble, just get a new one.

1987Comanche Posted April 2, 2010 Share Posted April 2, 2010 I've purchased 2 new ones off e-bay so far (JP5B if I remember correctly): one for my old '87 and one for the '90. They both worked ok and were around $95 shipped to my door. Link to comment Share on other sites More sharing options...
kastein Posted April 9, 2010 Share Posted April 9, 2010 :hijack: I went to replace the fuel tank on my MJ last night and discovered that the fuel pump assembly (the steel bulkhead bit that clips into the tank, specifically) is so rusty that I am afraid if I touch it, it will break in half. Clearly a new one is needed. Finding a place to buy one though... wow, it's kinda hard. The dealership says it's discontinued and has been for a long time. RockAuto says they have it (Bosch 67328) but it's $350! :eek: and it looks like they are cross referencing the Cherokee one to fit an MJ as well. I am afraid that the baffle/pan/bucket in the bottom of the new tank I got (the spectra SWB one, JP5B or JP4B I forget, it's definitely the right tank though) is in the wrong spot because the spare pump I have for my 96 XJ won't fit in properly, and I am pretty sure all pre-97 XJ tanks are interchangeable. Am I overthinking this? Should I just buy the assembly (amazon has the same one for 200 something) and stop worrying? Has anyone used the Bosch 67328 assembly successfully? For what it's worth, the cheapest I found was the Spectra tank, rockauto has it for a decent price. Link to comment Share on other sites More sharing options...
jimoshel Posted April 9, 2010 Share Posted April 9, 2010 I've bought 3 fuel pumps from Ebay for MJ, $30 each. worked good, No complaints. Link to comment Share on other sites More sharing options...
kastein Posted April 9, 2010 Share Posted April 9, 2010 Just the pump, or the whole assembly? My problem is that the assembly is so rusted it is on the edge of failure... my pump works great, in fact I drove it to work today. I can find a million people selling the pump but a new bracket/bulkhead/level sender assembly is rather more difficult :( Link to comment Share on other sites More sharing options...
jimoshel Posted April 9, 2010 Share Posted April 9, 2010 Just the pump. Looking at them, I don't think a XJ mounting assy would be that hard to modify to fit a MJ, and if you can't find a good one I may have one you can have. Link to comment Share on other sites More sharing options...
tallon2064 Posted April 9, 2010 Share Posted April 9, 2010 Be CAREFUL Cherokee sending units do not work in our Comanches. :fs1: I had the same problem with parts stores around here and they don't listen when you try to tell them that not all cherokee parts are interchangable. :fs1: :mad: You really don't want to know how I know this. :doh: The best way I have found is to pick one up on EBAY and make any needed repairs to it before you install it then you have a spare that you can repair then keep in case you need or sell and get at least some if not all your money back. There are places you can get you sending unit rebuilt for as little as $100 or so, at least that is what I have seen. I am in the process of trying to go this route myself, but you know the way money can get sometimes, have new to me sending unit just waiting to get the money to have it rebuilt before I install. If I can find the web site again I will post it on here, or maybe someone else can steer you in the right direction. I also remember seeing at one time, :dunno: maybe not in this club :dunno: , that their was someone who was a member that could rebuild our units, :wall: only saw it once and haven't been to find again :wall: , should have marked when had the chance. :doh: :rotf: Also have an EBAY gas tank myself and have had no problems with it, except the more I drive my Jeep the faster it goes empty. :rotf: Link to comment Share on other sites More sharing options...
kastein Posted April 9, 2010 Share Posted April 9, 2010 yeah :( no kidding. The counter guys at the stores near me are actually pretty good, once they realized I needed the whole assembly not just the pump they were like "yeah good luck dude..." I guess I'll take a look through the parts catalogs and see if I can find anything... might hit the junkyard, pull an early model XJ pump assembly and see if it's something I can modify to fit properly. It's just a piece of metal, why does it have to be so hard to find :( Link to comment Share on other sites More sharing options...
