We have two 101fc ambulances, both tanks are leaking, one needs adapting to automatic and left foot accelerator pedal. The other is a power steering donor and other bits. Can I por 15 both tanks with a modification? 100L in the original location, the other tank goes above it, where the little access locations house both 50 mm rubber hoses to connect them. Ideally I need the wheel centers and have Discovery 1 outers welded to them to accommodate tubeless tyres.
