Fill Neck Mod

[Bananaman]

I tried again a few minutes ago. I just keep ripping the outside edge up. I really put some squeeze to it too. Mine has to be glued in.

I'm with you, I've tried everything I read on here but it's not budging.
Been working on cars since the late '70's so I'm not a newby (not a Shadowspapa either, but have done some interesting stuff.)

This is a tough nut to crack. I've worked on cars since the mid 70's. ASE master tech. Worked on steam turbines, gas turbines, and some pretty weird shit. I'll get this sooner or later. I just have to let the temps go back up.

I ended up ordering a diesel fill neck from a Wrangler since it was only about $65 compared to double that for the Gladiator version. I got it out and stuck it in a vise and used 2 small screwdrivers to basically bend the metal part of the neck (flathead part sticking towards the opening of the neck) and then, with a larger flathead, slowly hammered the plastic part out. You have to be careful how you angle it because you can easily break the lip... which is what I did with the original neck I pulled off my truck.

A royal pain in the ass job, and I've done a lot of pain in the ass jobs. How anyone has managed to pull one of these out without removing the neck from the truck is beyond me. I just about chucked the broken neck across my yard when I was done with it I was so frustrated. But, glad I did it as now I have no problem adding additives or using any truck stop pumps anywhere.

I believe the problem people are having removing on vehicle, is they grab with the channel locks perpendicular and not parallel like in the video shown. Parallel allows the channel locks to only touch the rim which is what needs to turn.

once starting to turn, pay attention to the notch on the bottom. When you see the tab disappear all the way, that’s when you can start applying outward pressure. During this process you still want to be parallel with the rim.

This should allow you to do a proper rim job ?

I got me some medium-sized channel locks. Going to try this weekend. See how it goes.

Oh, i finally gave this a try over Christmas break. Worked! Initially i didn't think anything was happening, but i tried to rotate it the opposite direction from how I started (CW vs CCW or visaversa), and i noticed it rotated like 3°. So i went back and forth many times and the little plastic nub seemed to be wearing down...i guess the rotation was getting more and more noticeable to me. Anyway, finally it "went" that extra little bit to let me know i was rotated past the notch in the housing.

So then i went with this plan: I removed most of the plastic nubs so that i can insert and remove it "any time". I think i'll keep it in there to do its stated job of preventing the wrong pump from going in, but i can wedge it in and out with my fingers now if i find myself at a truck stop or with some other filler problem. The rubber gasket does most of the job of holding it in place. What's left of my nubs does the rest of the job. But I don't have much nub left to snap into the slots.

I like this idea as i do let non car people use my truck.

Hey all. Late to the party but new to the Gladiator Ecodiesel. I just pulled the guts out of my fuel fill neck and wanted to share an easy way to do it.

I started by trying to push in the tabs but couldn't access the top one well enough to push it in. So I tried something different.

I found a pair of wire stripper pliers that when opened, would fit between the ribs inside the filler neck. I could get enough leverage on the pliers handles to twist the plastic fill assembly to disengage the 2 tabs. Then the assembly pulled right out.

Once out you can access the 3 tabs that hold the trap door assembly on the housing and pop it off the bottom.

Once it's off, pop the top piece back in the metal fill neck and you're done.

This is basically accomplishing the same thing as trying to turn it with channel locks, but less chance of a slip and scratched paint.

So you did this without taking the fender off? Little to no chance of a small plastic piece breaking off and going into the fuel tank?

Correct. Opened the fuel door, removed fuel cap, insert the "tool", twist, and pull.

When you take it apart any pieces would be captured in the trap door assembly if they somehow broke off and fell inside. I don't see that happening because the plastic seems to be flexible enough that you would have to purposely try to break the tabs off to have that happen.

I suppose there is a chance you could shave a sliver of the tab off when twisting that could sit in the top opening of the metal fill tube. It probably wouldn't be a bad idea to try to brush or blow that out before pulling the assembly out as a precaution, but I did not notice any plastic shavings when I did it.

Someone please make a video!

Will removing this thing have an effect on when you fill up, the pump clicks and then if you put more diesel in slowly you can fit another 2gal?

Or is it just to allow the truck diesel-size nozzles?

 

[Jteakus]

This should be a mod every diesel owner should do. None of the shortcuts worked for me but I was able to drop the filler tube without pulling the inner fender. It wasn't hard just a little more to it than my JL.

Is there a benefit besides being able to use a truck-size nozzle?

 

[Jteakus]

That is the primary benefit. Secondary is the ease of adding diesel fuel additive.

What fuel additives are you using? I use once a year the Techron Diesel (it comes in a container that does not require a funnel or anything)
