Fuel regurgitates when filling--probable vent pipe issue

Hey Folks,

I have a 2003 Ranger Edge Super Cab with the 4.0 engine. Ever since I bought this two years ago (it was a project--I rebuilt the engine), when I go to fill the fuel tank the nozzle shuts off and in some cases the dinosaur juice will regurgitate out the filler neck, necessitating the use of rubber gloves when I gas up. In doing some research on the 'net, I found that it is mostly caused by a blocked fuel vent hose--either the flexible hose coming from the tank to the filler neck, or the steel portion of the filler neck where the flexible hose attaches.

I started troubleshooting by removing the rubber vent hose at the neck then attempting to fill it. Same issue. I then ran a stiff wire down the flexible hose (grounding it first, of course), and it went about 2-1/2 to 3 feet then stopped. Next, I used low-pressure air from my compressor/tank--it would pressurize slightly, then, when I removed the air nozzle, there would be a light rush of air from the hose for several seconds indicating that there was pressure wherever the hose was going.

It appears that I would need to remove the bed in order to access the top of the fuel tank--something I am NOT looking forward to.

Damned Ford.

If anyone on this forum has experienced a similar issue, I would greatly appreciate any suggestions. If there is a schematic and/or pictures showing the routing of the vent hose please provide the links.

This drives me nuts whenever I fill the tank because I need to hold the fuel nozzle valve open very slightly, therefore taking me 10 minutes or more to fill the tank (and other drivers look at me funny because I am usually mumbling "Damned Ford" while filling the tank).

Thanks in advance for your help.

Not a Ford issue my GM car does same thing, and when its cold out...........1/2 tank is good for now, lol.

You have a kink in the filler hose, and yes bed will need to be moved back or tilted up to get access to it.

Loosening the 6 bed bolts is usually the hardest part so start there to make sure you can remove them, and if not take it somewhere that can get them out and then reinstall them so you can remove them when you are ready to swap in a new filler hose.

Google: ford ranger fuel filler hose replacement video

Lots out there, and the different methods

Need a Torx-47 for the bed bolts

2 are longer than the other 4, picture here: http://www.explorerforum.com/photopo...621121013a.jpg

Up to you to replace or repair filler and vent

Uh, those are T-55 bolts in my 2002 Mazda/Ranger. I lucked out and mine came out easily. (I had the bed off to replace the fuel pump/sending unit but must have kinked the hose or ? since it is now puking fuel.) And don't forget to remove the three screws that hold the filler neck to the bed! Don't ask.....

I unfortunately, had a similar experience with my 93 ranger. Replaced the filler hose some years back, and, following the installation, had quite a bit of difficulty with filling the tank. Came to find that the smaller hose running down the inside of the filler tube was kinked. Here is what I am thinking may have happened during that earlier install which may have resulted in the kink: many of these aftermarket hoses are inexpensive replacement parts, and so we have to adjust them to get them to fit correctly. One such adjustment that is somet8mes needed is when we finish the install and need to bolt the filler neck to the body. Somet8mes we need to rotate the metal neck to get the holes aligned. When and if we loosen the metal hose clamp and give it a little twist to make the holes l8ne up, then we have , inadvertently, twisted or kinked the inside smaller hose which is the one that the fuel flows through when you are filling up the tank. When I disassembled mine to install a “ better” hose, I cut apart the old 9ne to see just exactly why it was not flowing . It had a nice twist in it. So make sure that you pull the entire smaller hose out of the larger hose to inspect and align them then reassemble them prior to install8ng the filler hose on your vehicle. Gotta keep the inner hose untwisted.
