Cab Gas Filler Hole

Anyone who is moving their cab mounted tank to under bed?

What do you do with the old cab hole?
Weld in a piece of sheet metal?

Another thought I had was to saw off the fill neck from the (internal) tank
shove it through the rubber grommet and put a gas cap on it, and make it
look like I still had an internal tank.

Other ideas? An easier way?

"Another thought I had was to saw off the fill neck from the (internal) tank

Re: Cab Gas Filler Hole

LMC truck sells a pre-cut sheet metal piece that is a good fit. buy that and weld it in.

Re: Cab Gas Filler Hole

I just did like you mentioned I cut off the filler neck but I welded the bottom of the filler next up tight and painted it black. Its not in the truck yet but it should work good.

Re: Cab Gas Filler Hole

Whoa. Isn't anyone worried about sawing a fuel tank?

When I did it once for my Camaro, I took the tank out and filled it with water. If it's been empty for years, maybe. But gas fumes plus spark will ruin your whole day.

Re: Cab Gas Filler Hole

The tank had been completely emptied and sitting for 6 months outside and open. I then filled it with water and made sure that nothing else was in there. I had no issues after doing this with cutting it. But yes need to be careful with doing this.

You can easily put a rubber chicken into that hole

Re: Cab Gas Filler Hole

I welded mine up but I painted the truck after that.

With that patina I'd put a filler neck with a red rag shoved in it for effect

I wonder how many gallons that would take. I guess it would depend on how good your door seals are, and whether you have rust through the floor.

Re: Cab Gas Filler Hole

I left the rubber grommet on it, put the gas cap up to the grommet, put a 6" bolt on the back side, and used two zip ties to attach the tabs on the gas cap to the long bolt. No need for it to be a bolt, anything about that length would work, a pencil, dowel, branch, etc.

I personally like the rubber chicken solution proposed earlier!

Re: Cab Gas Filler Hole

It has been mentioned that a few places sell patch panels for this.
Does anyone have a link?

My uncle's late 1960's Lincoln was rear-ended by a large truck and the gas tank was punctured.

My dad welded up the punctures while the tank was on the car and 1/2 full of gasoine.

How did a man manage to do that without an explosion? Easy! The Fire Triangle.

Gasoline (like most everything else) needs three things to burn. Take away any of the three and it cannot burn. Dad ran a hose from his (now my) truck's exhaust to the tank nozzle. Then he idled the truck before and while he was welding. Carbon monoxide fumes displaced the air (containing the essential oxygen) and the gasoline could not burn or explode.

The coal mine where my dad worked didn't call him "The Doc" for nothing!

Re: Cab Gas Filler Hole

I just picked up a chrome gas cap from LMC, and then we took it apart, and fabbed up a mount from the rear to hold it in place. My truck's paint was good and I didn't wanna do any body work and fill it etc. the original rubber worked nice to seal it up.

Re: Cab Gas Filler Hole

I love my dad's suggestion and I might just have to try it. My filler is just the neck welded closed with the cap on it, he said to put one of those spring snake things that were in the old can of nuts. It would be a good funny joke.

Re: Cab Gas Filler Hole

Put a piece of cardboard behind it , use a sharpie , make a pattern, pick up some 16 gauge plate at hardware store, cut it out with a jig saw , clean it up with a grinder. Then weld it up with a mig. You could probably do it with a cheap flux welder. This particular spot is very ridged and will not warp very easy. Slap on some filler and paint . Wala

This is true , my dad showed me this too . The first time I ever saw him do it everybody scattered thinking this man was crazy . Even seeing it and being there never really quite prepares oneself for that first arc of a welder on fuel tank . Nerve racking but it get easier the more you do it lol
Thank you for posting , this brought back some great memories of superman ( my dad)

peace
