fuel tank inerchange Reply #2 – January 27, 2008, 11:55:46 PM from the ones I've seen physically it will fit but the mark7 has a single fuel pump and fuel level sender in the together, as a thundercougar has separate ones. so maybe yes with some wiring mods Quote Selected
fuel tank inerchange Reply #3 – January 28, 2008, 12:03:56 AM I was gonna add that the parts disc I got shows the Tbird and Cougar as the same, and the Mark VII and Continental as the same. But like Cougarman says, physically they might fit. Quote Selected
fuel tank inerchange Reply #4 – January 28, 2008, 12:10:39 AM i used an 88 thunderbird fuel tank in my 83 (the 88 has the fuel pump and the sending unit in seperate holes)... the tank was a gallon or so bigger so the strap bolts didn't tighten as far, but it has the same shape as the cfi one and hasn't given me any problems in over a year.... the pics i saw of an 84 mark vii fuel tank show it as having the intigrated cfi fuel pump/sending unit design like my 83 did..... i think you have multiport in the 85, so an 85 or later mark VII tank should work (it has the seperate holes)--- it looks the same as the one i got from the 88.... they say the mark used the same fuel tank from 85 to 96, but i'm not sure......hope this helps Quote Selected
fuel tank inerchange Reply #5 – January 28, 2008, 08:32:43 AM The '86 LSC I had used the exact same tank as the '87-'88 TC, just had to swap sending units and pump assembly's...I believe the '86-earlier birds used a smaller tank... Likely could be swapped as long as you use the correct straps and cover... Quote Selected
