I am in the process of planning to build a auxiliary in bed fuel tank. It will be made out of stainless steel so I am looking for a SS filler cap and/or filler neck that can be welded on. Are there any vendors that sell a good looking product, or does anyone have any other suggestions of fabricating one. I have seen some that bolt on, but would rather weld one on and be done with it. Thanks guys any advice is appreciated.

Bump, No one has any ideas or products?

I planned on building one also, until I priced out the metal and figured in my time. Was more cost effective to buy one, plus for $450 it included the DOT placard. If you haul commercial or even not DOT can nit pick little things like that. Anyway, it sounds like a fun project if you have the time.
Here's what I found, among others on ebay.
