mk3 petrol to diesel - fuel tank

[Luke]

is there a difference in the fuel tanks on a mk3 petrol and diesel fuel tanks

its just i am swapping my mk3 from petrol to diesel - just wondering whats the easyest way as i have a full donar mk4 diesel van
swap the fuel tank or the sender or are they the same

my mk2 has been converted the other way round !! the pipe work is still there for the flame heater looks they just drained the tank and swoped the engine but heard of new cars filled with wrong fuel and the sender failing latter !

hi luke i have done the same as you to several transits..(as well as fiestas)and i have usually used the petrol tank as they are the same.except for the sender unit.the petrol one has 1 outlet and the diesal one has 2.. 1 for the fuel outlet and 1 for the return.even though on the luton i have now i have cheated a bit by using one of the vents on the tank(there are 2 vents on the tank so am alright)as the return and the sender uniit is still working ok and i have done about 3000 miles since i did it..
