Gas filler neck hole cover?

[XtechX]

I went ahead and relocated a 78 blazer tank behind the rear axle on the 65 lwb, as an after thought. I have already painted the truck, so I can't just weld the filler neck hole shut at this point. Any cleaver ideas on how to cover the hole up? My plan so far is to remove the in cab tank, and clamp the original filler neck into place so it looks like the tank is still there and for added insurance, use a locking gas cap to make sure someone doesn't fill my interior up with gas. It's the best plan I have so far, what do you guys think I should do?

put a bottom on the filler neck and have a locked cubby hole

I used the stock grommet and filler neck, and the rubber coupler that attatches to the tank. At the bottom of that assembly I put in an abs plumbing cap (can't recall what size). It is hose clamped onto the rubber coupler.
On the outside I epoxied onto the metal filler neck a gas cap that I made from a horn button from the standard steering wheel from our trucks.

No way you can accidentally fill my cab with fuel.

take a spray can cap and wrap some shop rags around it and cram it in the hole. gives a wtf vintage look. did it to my old 64, you can see the effect on you tube search; dave's airride chevy truck

Thought about using part of stock tank tube with locking gas cap. Hate to mess up a good inside tank...but what do you do?

I did the same... just left the filler neck and cap in place.

Any other ideas on how to fill stock hole after relocating fuel tank...

I machined a plug out of a piece of 3" aluminum. One end looks lust like a gas cap and then it necks down to a little bigger than the stock tube. Put it in with a new rubber grommet and just a touch of super glue. With it painted white it looks just like a stock cap and with it being a piece of solid 6061 no chance of any one getting the cap off.

I jb welded a stock looking cap to the end of mine and painted it the same color as the body.

I beat a piece of old fender into a patch that fit inside the body, and adhered it with JB Weld. It's been in place for 18 years and still looks like it was just put in place:

I removed my tank and left the cap/fillerneck in place. No clamping needed.

I'm just gonna leave the filler neck in too

In 1965 American LaFrance Fire Engine Co. removed the cab tank and added a 50 gallon tank under the rear frame. They put in a chrome plated button plug in place of the filler tube. It's still there in my C80 truck.
