I searched the forum for this issue but did not find an answer to my problem. When fueling the nozzle shuts of repeatedly after a couple seconds. I have to fuel VERY slowly. No splashback like others posted but cannot get the fuel to go in quickly. This new to me 2004 LJ had to have a new fuel pump and I noticed valves or flaps in the feed tube and tank. Are these the cause? Saw some comment about an anti spill flap in case of a roll over. Did not know about this problem when the tank was down. Really annoying but I don't want to drop the tank again if I can do a work around to disable a restriction.
IMHO you're gonna need to drop the tank. But yes the issue usually is with the small hose near the filler neck and I believe that's all tied into to the evap system.

Might have to live with it then. If there is a way to make the feed flow better then at some point I might have to do that and it would be easier the second time around but I'm not sure my buddy would still be my buddy if I ask him to help again...at least this soon.
Slow fill and splash back are both issues for the same problem.
However, if the Jeep is new to you; check to see if a PO has altered the fill hose.
Check for kinks and/or a bulge.

When I bought my 01 tj it used to take me 15 mins or more to fill up. I ended up pulling the filler hose off the tank and in the neck of the tank was what looked like a ping pong ball and a long spring. I didn't have to drop the tank either. I guess it was for fuel spillage if you flopped over. But the plastic ball was crushed and wouldn't move it was stuck. So I got some long needle nose and pulled the ball and spring out and now its normal. Fills up fast and no blow back. My guess is someone was trying to siphon gas and smashed the ball trying to get the hose down in the tank.
Aside from being annoying, this is an easy fix.

Having disconnected the fill tube once already I know what to do to get that off and hopefully I can get the ball and spring out. And I placed the clamp to remove the fill hose in a better position figuring I might have to go back there one day. It was a problem where the factory placed it. There is a metal strap as part of the hose assembly that is probably a grounding point and that was a problem to work around. Thanks for the info. I did see the video when searching for fixes but was not certain that might be the problem since I was not experiencing a splash back. But maybe the new hose nozzles were preventing that.

But maybe the new hose nozzles were preventing that.When the plunger is stuck in the down position you get splash back. When the plunger is stuck in the up position you get the pump shutting off every few seconds resulting in slow fill.
Either way it's a problem and I know where I would like to stick that plunger on an EPA administrator.
