need to order my fuel lines,car is not here,
Its a 1985 5.0 Capri should the fuel lines from
the tank to pump be 5/16 or 3/8

50 resto shows every year but 85
but looks like 5/16 for all the other years.


Thanks

If you're redoing all the lines i'd go with 3/8. Eventually as you make more power you'll need more fuel than the stock lines can provide anyways.
