Blazer filler neck for boyd tank
 

Would this idea work? I have a Boyd Welding tank with a side exit instead of top exit. I want to retain a stock look, which is why I'm thinking of the Blazer filler neck option. I don't want to do a fuel door on the side, to me it looks too 80's. Tail light hidden idea is a good idea, but I dont have a ton of time to devote to it because I'd like to drive soon and this is really one of the last things holding me back.

Anyone done this before?
