Tank Mod Help!!!

[MDRhoads360587]

I have been looking on here for a while and cannot seem to find a thread on how to fix the filler neck problem on thes OBS trucks. Could someone direct me to a good indepth mod thread? Aggrevates the heck outta me at the pump filling up $.05 at a time. Lol.

I feel your pain. I don't have a fix but with the pump on it's lowest filling speed and just barely resting on the filler neck I can get a good 10 gallons at a time before having to go back and hit the trigger again.

Try using the big diesel nozzle at the pumps. Although it doesn't make any sense that it works, it really does. I can fill the tank to the brim without it clicking off. Just be careful as it gets toward full so it doesn't run over.

I tried that the first time I filled it up cuz I used to use it on my 6.0 and it filled up FAST. The big nozzle won't fit in my filler neck.

Look in a junk yard for a cab chassis obs and grab the roll over valves and cut out the tube in the center and run an external vent tube on the outside. They do make aftermarket kits, but from my understanding they are like 500 bucks and the same exact thing u can get at a JY

Agreed
air out as fuel goes in is the solution

Yes, the Transferflow fillerneck kits are at least $500, if not a little more, but they work good and are fairly easy to install, we have them on both of our work trucks.

The Transferflow ones are great. I have a pair in my OBS and can fill to the top much faster than my SD with the tank mods.

The ones listed on their site are for 1999 and up. Do they have them for OBS? Mine is a 97.

They did back in the 90's, not sure if they still have them. When my 95 was new I helped the PO install a 40 and 45 gallon Transferflow tank along with the filler necks.
