Srfcr8, I'm running "Tanks" Saddle fuel tanks made of polypropylene in my 31 Coupe. They're alright. Plumbing is a pain and I didn't by fuel injection ones. They weren't available yet, I would highly suggest that. If you have fuel pressure problems, which I've had, you could run Injection pumps in the tank and solve many problems. Another issue is filling the saddles and the amount they hold. Seven gallons per side, so you will have about 5.5 gallons of usable fuel per side. Not a lot. You can buy a fuel selector valve from JC Whitney that will handle pressure up to 65 PSI with 6 Ports, 2 in, 2out and 2 return. I'm running that one. The other choice would be Rock Valley, they make stainless tanks.
