I plan on using an OEM fuel filler cap/tube for the spare bed fuel tank.

What would be the OEM fuel filler neck size for a 2010 F-350, 6.4 PSD?

I have to get the proper sized bung to weld into the new spare tank, so it is ready when the new rig arrives,
and I'll have the spare tank finished so it can be spray coated with the bed liner material when the bed is coated.

Since no one had an answer, is there I site I can go to find the information?

The filler tube and vent (in the fender) connect to the filler neck (and vent) on the tank with a standard fuel hose (1 1/2" interior diameter)

Be warned that this hose is hugely expensive and does not like to bend.

 

Pbeering,
Thanks for the info.
By any chance would you know the vent tube size also? I forgot the PSD have a vent tube for filling etc. (Old 73 F-250 390 had none).
New to owning a PSD rig.

I plan on using just the top section of the OEM filler neck and cap, I have a metal Caravan camper that will be or have the OEM door,cap, filler neck and the piece that attaches to the filler neck top, (filler neck deck)? made to fit the camper wall/side.

The new 50+ gallon fuel tank will then be plumbed to add all the above parts, I can then find or make the rubber filler and vent tubes to fit the distance and angles needed etc.

Thank you,
Don
ps, would there be a site here that would sell or have these parts?

 

The vent hose is 1/2" interior diameter.

Before you get too carried away with this project you might talk with Titan Fuel Tanks and Transfer flow.

I installed a Titan tank in the '08 and have been very pleased with the increased range. Others have been happy with Transfer Flow. Either system is turn-key.

 

I've been searching and searching for ways to plumb a fuel filler through my Caravan as well. I'm new to this site and can't seem to find a way to send a personal message, but I'd sure like to know if nvreloader or anyone has any ideas. It seems to me that I'd first need a filler neck housing and/or a fuel door? From the thread it appears as if welding in a factory door is an option. That seems almost an impossible challenge without cutting up a new bed. Thanks for any ideas.
