Aux Tank Filler Neck

[PbFut]

Can anyone confirm this filler neck can be used (shortening the tube) for a factory style filler neck on the factory aux fuel tank that goes behind the added cover in the bed? https://www.holley.com/products/fuel...0aAipjEALw_wcB

If it helps you in determining compatibility the fuel filler is 1 1/4" diameter.

The key issues are the length of the neck to the flange, and from the flange to the outside of the tube going down. It looks to me like the the same engineering as the original factory aux tank neck with an extended tube going down on this available part. Simply cutting the tube would make this a match to the original part for our truck. The flange would mount to the inside of the bed like the original. Tube runs next to the bed wall through the bed and to the top of the aux tank using a connector hose. The filler and vent tubers are behind a sheetmetal box in the bed on the factory set up. The sheetmetal is available so that's easy. I'd like to mount this filler neck so I have a factory style filler on the passenger side to match the drivers. I guess I can try to call one of the vendors that sells the part tomorrow.

Thank you
You confirmed it sits behind the OEM style cover and how far it sticks out of the fender.
Exactly what I was looking for.
