79 Firebird Project TigerHawk

I had the idea to use a factory tank from something that mounted vertically behind the seat / under the parcel tray......only downside is putting weight above the roll centre - which a fuel cell would do anyway. At least a vertical tank would give more trunk room and give plenty of under floor area for some Vette style mufflers and centre outlets. Add a quarter panel mounted flip open filler, or modify the trunk lid so a filler/mount with drain sat through the trunk skin. didn't do it on my 71.....maybe next build.
I actually set up the tank system in my 34 Ford Roadster this way.....tank right behind the seats. Worked very well.

Thats a good idea on the fuel tank,I am going to do a flip open fuel filler on the quarter panel.

I looked int that for my Camaro. A fueltank for Opel manta GSI or GTE will fit perfect in that location. Opel is also GM :-) . The filler neck on top need to be cut 10cm or 4" from the tank an rerouted to the q-panel- The tank is mounted behind the rear seat on the Opel so it have the fuel sender in proper position and it have nice mounting flange to the body. For thoserunning EFI the pump will be gravity feed without placing it to low on the frameraills or floor.
The only issue is the weight added above rear axle. approx 50kg/ 100lbs. That is the only reason fornot doing this, The package room it takes up is minimal of the space we use.
