I'd be careful with fuel tanks! I got a new copy tank with the metal swirl pot and had it modded to aero quip fittings and took the genuine ford plastic swirl pot tank out and fitted the other one
I did this so the car was not in bits for ages with no tank in it!
My car has an m.a.d 500 set up on a gt30 that's been faultless for about 3 to 4 years as soon as I put the cheap tank in it started to fuel surge!
Genuine tank will be getting painted modded and put back in lol copy will go in the bin!!!
