Blacksurt Glad you got it going...the "extra 4 gallons" comes in handy for sure.

Hey thanks for the response. I ended up buying a completely new fuel sender unit that came with a new pump, filter, and pressure regulator. Given that the original unit was still on the TJ built in '99, it is good insurance. Cost me around $200 on Amazon for the Omix-Ada part. Talk about a product that is hard to decide which brand to go with. The local stores only carry Airtex which get horrible reviews online, so I ended up ordering on Amazon and got the Omix-Ada.

Last night I have the new sending unit in and have the tank jacked up to about the point where I can connect the fuel lines again and the electric plug to the fuel pump. I grab the fuel pump cable from the new sending unit and the old cable leading to the front of the Jeep and I literally almost crap my pants. THE BRAND NEW OMIX-ADA UNIT HAS A FEMALE ELECTRICAL LEAD. The OEM unit has a male lead and the wiring harness going to the front of the engine has a female lead. WTF!

I keep my cool and cut off the old cable attached to the old sending unit, cut, crimp, and solder the old sending unit male lead to the new sending unt and thankfully everything appears to be running.

I plan to send a complaint to Amazon about the pump (the one I bought is sold by Amazon). Talk about a manufacturer defect!

Need help quickly bc my jeep is sitting in the garage completely disassembled.

Thanks.

Blacksurt I replaced the sending unit alone on mine, dealer about 30 bucks....and it came with a new gas tank seal ring. As far as the 15/19 sending unit I don't know if they are interchangeable.

Ichabod Digging this thread back up because I'm having a gauge/sender issue.

Can't I just get the pump/sender for the 19 gallon tank from a 4.0 model and install it in my SE?

I ask because I suspect my sender is shot, and if removing it and cleaning it up doesn't fix it, I'll replace it anyway.

I'm guessing that since all TJs have the same tank, the fue pump/sending unit is the same except for the longer neck/vacuum tubes, right?

And just to clarify, I have to replace both because the pump and sender are all one unit, right?

cheap_jeep Genright has a 22 gallon

Pk64f100 is there any aftermarket gas tank that holds more than the 19 gal stock that can be bought? If so anyone know where to get?

1slo_CR On my 06 Dodge I added a vent to the highest point on the tank and put a "T" in the factory vent tube. Its only a 35 gal factory, after the new vent its 39.5 gal. And when filling, it doesnt pop off the gun its actually full!

CJS98TJ That's a cool free mod! I never knew about this one. Maybe someday I'll do it haha.

I think you are a natural artist. Hahahah

The tubes themselves do not take up 4 gallons of space. It has to do with when and how the nozzle gets tripped to shut off. You can "milk" the extra 4 gallons but it takes more time to get the last 4 gallons in than it does for the previous 15.
Here is the type of cutter I use to cut the tubes. No mess and makes very quick work in one snip per tube.
General Tools 119 PVC Pipe Cutter

Peepers I know my jeep will take 18.2 gallons with out changing anything and those two hoses are still in place (98). I believe the 4 cylinders came with the 15 and the 6's came with the 19.

I believe by shortening it, because it is on an angle you raise the point where the fuel starts to cover the vent hole, which i believe is part of what trips the gas nozzel off.

You could also try parking on a slight incline so the passenger side is lower than the drivers side...
05-26-2011 11:12 AM
Mike_3303 I know ive hear of this mod before but i just dont see how removing a tube or two will free up that much room fro an extra 4 gallons or so. oh and by the way, love your stick figure drawing lol
05-24-2011 11:03 PM
Blacksurt That is what the mod is for, they are all 19 gal tanks. My base model came with a "15 gallon" you have to cut the tubes in order to fill to 19 gallons. You had to pay extra for the "19 Gallon tank".
05-24-2011 10:41 PM
AzTJ You do know that they are 19gal right? At least my '97 is from the factory...

Double_Trouble Wish you'd do it again and take some pictures - I'd love to do this.

Ggg Glad this benefited you. Ford diesel trucks have the same issue and this mod is commonly called a "harpoon mod". Most of us use PVC cutters to cut the fill and vent tube as close to flush as we can. The PVC cutter uses a large razor blade to make a smooth cut so no saw dust, burs, or shavings to deal with.
