I am looking at moving/replacing the fuel tank on my 56 to the rear using John Niolan's excellent article as a guide. My dilemma is whether to modify the 22 gal 1970 Mustang tank to incorporate the hardware necessary to support a fuel injected late model engine. I am considering a late model driveline with fuel injection but I would need to modify the fuel storage/delivery system to make it work. I have a couple of late model plastic tanks that have all the plumbing, and I have seen some vendors who sell specialty tanks that have the appropriate openings and mountings for this hardware...what I haven't found is an early Mustang tank that has this capability (yes, I did speak with the folks at gastanks.com but they couldn't help me).
Has anybody ventured into this realm yet? Tried to use the "search" but it seems to be unavailable. Thanks...
The folks at Gastanks.com get pretty funky about their tank going into a non-stock application, so I'm not surprised they weren't much help. Liability stuff, they said.
There were no early Mustangs that were EFI, to my knowledge. However, the Mustang tank isn't the only option for a rear tank. I mounted a Bronco tank (check my gallery). Tacson and Ferguson777 mounted a Chevy van tank. The Chevy tank fits into the frame without frame modes. The Bronco tank only required moving the rear crossmember to the rear set of spring hanger holes and flipping it over.
Basically, all you have to do is find one that fits in the frame opening. It isn't a daunting mod to do. There is an article put together by Fergie that discusses the rear tank options very well, but I don't know where it is stored now. Maybe he'll be along to show you.
Charlie,
I used a mid 80's Chevy Blazer tank in my 49. It fits between the frame rails nicely (I think there is a pic or two in my gallery) The tank comes in both a 24 and a 31 gallon, I ended up with a 31 gallon (it was a freebie) If you get a tank for an 1987 or later Blazer (or Van for that matter) it will be set up for fuel injection. GM went to throttle body injection in 1987.
The filler tube on the Blazer tank exits towards the right side of the truck. I routed mine between the top of the frame rail and the bottom of the bed.
So basically, you have your choice. If you are looking to keep it all Ford when you go for your fuel injection, use the Bronco tank. If you are going with GM fuel injection, go with the Chevy tank.
You might also give some thought to what guage you will be using also and try and match the fuel sending unit to it.
If I had to do it again I would try and find the 24 gallon tank. I mounted mine up even with the top of the frame and it still seems like it hangs a bit low.
If you work a deal on the tank, see if you can grab the straps, filler tube, etc
