I've owned my KJ for almost two years and this just started happening about a month ago...just about every time I tank up it will spit some gas out right towards the end of the fill. Usually it's not much but today it was enough to leave a puddle on the ground and piss me right off.

What gives??

Sometimes on my kj when I fill her up the pump acts as if it is topped off....maybe same symptoms just yours sound worst. In the ambulances here at work if you try to round the number after it clicks the tank vomits out fuel also....is that what your doing? Just a thought

Mine does that every time I fill it up. It sucks because usually I am stuck going the rest of the day smelling like gas from getting it on my hands. Somehow the smell just sticks to everything though even after washing.

There is a TSB in the KK forum about the KK getting a fix, but nothing on the KJ spitting fuel.

There is this for a KJ, though:

TSB FUEL SLOW FILL ISSUES

NUMBER: 14-001-09 REV. A
GROUP: Fuel
DATE: September 1, 2009
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 14-001-09, DATED APRIL 15, 2009, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED TO HIGHLIGHT REVISIONS.
SUBJECT:
Hard To Fill With Fuel Or Fuel Nozzle Shuts Off Repeatedly
MODELS:
2005-2007 (KJ) Liberty
NOTE : This bulletin applies to all vehicles equipped with a gasoline engine.
DISCUSSION:
Customer may report that the vehicle is hard to fill with fuel or that the fuel pump nozzle shuts off repeatedly while trying to fill vehicle.
This customer complaint can occur due to a number of different causes. The fuel tank is the least likely cause of this condition. The following Diagnostic procedure can be used to diagnose the issues.
DIAGNOSIS
1. Is the vehicle a LX/LE/LC/L2?
2.If yes idle for 60-90 seconds before filling.
3. Does tank refill properly?
If no proceed to step 4.
If yes Inform the customer to idle the vehicle for 60 to 90 seconds upon stopping if vehicle was driven aggressively. This is due to the fact that on the LX/LE/LC/L2 the fuel tank is a unique saddle tank design and needs 30 to 60 seconds while the engine is running to level the fuel in both half's of the fuel tank. Allowing the vehicle to idle for this amount of time will let the fuel pump transfer fuel to the left side tank, opening the control valve and allowing normal fuel filling.
4. Disconnect the vapor recirculation tube at the fuel tank.
5. Attempt to refill fuel tank.
6. Does tank refill properly?
Yes >> Proceed to Step # 7
No >> Proceed to Step # 11.
7. Reconnect the vapor recirculation tube at the fuel tank.
8. Disconnect the other end of the vapor recirculation tube at the fuel filler tube.
9. Attempt to refill fuel tank.
10. Does tank refill properly?
Yes >> Replace fuel filler tube.
No >> Replace the vapor recirculation tube.
11. Disconnect the control valve to EVAP canister tube at the fuel tank.
12. Reconnect the vapor recirculation tube at the fuel tank.
13. Does tank refill properly?
No >> Replace Fuel Tank.
Yes >> Proceed to
14. Reconnect the control valve to EVAP canister tube at the fuel tank.
15. Disconnect the control valve to EVAP canister tube at the EVAP canister.
16. Attempt to refill fuel tank.
17. Does tank refill properly?
Yes >> Blockage is in the EVAP Canister, or ESIM, or Clean air hose (ESIM vent hose), or filter. Diagnose appropriately.
No >> Replace the control valve to EVAP canister tube.

I just slow the flow down by holding the gas pump lever lightly when it's about to be full. Works most of the time. I have heard that having the pump in at an angle stops it too; didn't work for me though.

X4 I stand to the side, and even though my tank allegedly has 20.5 gallons of space. I've literally rolled in to gas stations down hill in neutral with the vehicle off. Around 18 3/4 and 19 gallons of fuel it shoots out all over the pump and all down the side of the jeep. Yes fueling slower "helps" but this issue still occurs

Mine does this EVERY time since I bought it last year. I just pump it on the slowest setting and relax.
