2008 Ranger Supercab 2.3 5 speed 2wd truck sat for almost 2 years as I had several things to address on it and a shoulder surgery kept me from it for the better part of a year. Replaced valve cover gasket, fixed broken bolt in cover that the pcv valve mounts in, replaced water pump, thermostat, serpentine belt, new plugs, and wires. Before starting, used an electric fuel pump to drain the old gas from the fuel tank. Shoved a hose in thru the filler neck to pump it out. Put fresh gas in with a gas can and test drive it, and it runs great, just like always, with no check engine light. I've fueled the truck several different times at different gas stations and the nozzle clicks off before you can even set it on the lowest notch. I've owned the truck since 2018 and I always been able to gas it up full blast in a few minutes with no issue. Set the nozzle on high flow and let it go or hold it wide open, either way it'd take gas as fast as you could send it. Now it takes 10-15 to fill up. No collapsing or kinks in filler neck or vent hose. Vent hose has no blockage. Wtf could be the issue? Is there a flap on the top of the tank for rollover protection that could have got messed up when we pulled the hose out after pumping out the old gas? Scanned to check for any inactive codes and the only thing there was an ABS code, nothing related to the evap system. Any help would be appreciated!

 

There is an anti-siphon valve (some sort of ball type thingy, if I remember correctly) in the filler neck. I'm surprised you were able to get a hose in to pump it out. It's possible you somehow wedged it closed more tightly than it should be. I wonder if you could try a short burst of suction with a shop vac on the filler port with a nearly empty tank to try and loosen it, assuming it's somehow wedged or compressed in the filler neck.

 

Thanks for the tip, I'll give that a try before I drop the tank.

 

Your vent tube may be pinched or clogged too.

 

Vent hose isn't collapsed or blocked.
