Well, after moving my fuel tank under the bed on my '66 shortbed and getting rid of the in-cab tank...


I still had this....sure I could have left it but eventually I probably would have had a brain fart and filled the cab full of gas!


In the January issue of Custom Classis Trucks magazine there is an article on filling the gas hole on a '65 F100...


Using the article as a guide, I proceeded to cut out the structure of the hole...


I decided to keep trimming like they did in the article...just figured it might be easier to form the new piece with a couple of the edges straight...




After trimming the hole I used a piece of thick paper to make a pattern for the patch....I cut it about half inch bigger to allow for stretching & trimming...




I used a body hammer and a flat piece of iron to form the new patch. I used these magnets to hold it while testing the fit...


When the fit was satisfactory, I welded it in. The best thing about my welding is that I also have a good grinder!!



After grinding smooth, I rolled on a coat of SPI epoxy primer. Then I added a skim coat of filler...


After sanding that smooth, I rolled on a couple more coats of epoxy to hold it till I can get it painted....

 

Looks good. I just did the same this past week. Makes for a much cleaner look (mine was just an open hole, as the filler was removed).

 

Thanks for posting this. I need to fill this hole on 3 of my trucks. And was wondering how everyone made there patch panels either just making a piece for the hole or cutting it out more like you did. Nice work on the patch looks like you got it to fit nicely.

 

Looks great.

 

Good job on plugging your gas-hole. So many ways this thread could go wrong, but I'll leave it be.

 

I have to say, I like the way you placed the fuel filler neck behind the license plate. In my opinion, this is the most aesthetically pleasing solution for those that opt for an under bed fuel tank. I never liked the look of a fuel filler trap door in the bed of the truck. Congrats on a job well done.

 

Thanks, guys!

 

Yes, Very well done indeed.

 

Have you tried to top off gas at the pumps yet? If so did the tank accept the capacity? Curious due to filler neck location. I like the location and as was pointed out by 66f-100 this the most aesthetically pleasing location.
Reps sent your way Good job

 

Well, since I've had my engine/tank swap running since last May, I'd say I've definitely filled it quite a few times.... and here's my experience with it thus far....it's a kinda slow fill at the pump. The filler neck is fairly shallow so I put a small baffle in it thinking it might help with possible slosh-back on rapid acceleration.


That baffle may also contribute to the slow fill but I'm not sure. I use the slow setting on the gas pump and it usually works fine and when it clicks off, the tank is completely full.

There are a few gas pumps where the slow setting is still too powerful and I have to manually fill the tank. It's just a 16 gal tank (the only size Tanks, Inc offered with EFI setup) so it doesn't take too long.

I'm also using a fill-thru gas cap which works great depending on the type of nozzle they have at the gas station. If the nozzle won't go in far enough to trigger it, I just unscrew the cap and fill it the conventional way.

 

Nice Job! What gas tank did you install...Pics?
(Edit) Oops, never mind. I was typing my question as you were posting the answer: Tanks, Inc!

 

There's a little more info in my engine swap thread on page 10, post #143

Hey Randy, That's some good information, I'm sure it will come in handy.
Once again good job.
