My wife loves her red F100 stepside "because it has hips" (fenders). Well, I'm thinking about modifying one of those hips for the while installing a second fuel tank under the bed.

Does any body know what material these fenders ar composed of? They appear to be some kind of composite (I don't think they are fiberglass). For sure they're not metal.

I have a gas tank off a '76 Mustang II that will fit nicely up inside the frame at the rear (did it to my 1970 F100 and it has worked great for over two years).

I want to place the filler tube in the rear section of the driver's side fender (in front of the taillight and the reverse of the existing one). I would like to be able to transplant a filler "door" from another fender or mold one myself and fiberglass it in, if possible.

Has anyone worked with this type of material? Can I do it?

Here's a rough sketch of what I have in mind (try to ignore the stars):

*****************************************FRONT OF BED
***********************************____
**********************************/
Factory filler location--------->/
******(w/door)****************/
*******************************|
*******************************| Fender
*******************************|
********************************\
"new" 2nd filler location------->\
******(w/door)********************\
*************************************-----

The tank will be installed too high in the frame to put a filler tube behind the rear bumber (license plate area).

Thanks for any suggestions.

Old Fords bad attitudes

 

Just grab a standard 80-84 F-series rear tank, the chassis is set up to mount it... As for the fenders, I'm pretty sure they are 'glass...
