Metal fuel line from to fuel tank cracked or has pin hole leak between coupling and fuel tank. Coupling on fuel line is 13 mm. Seems every repair kit or line replacement calls for either 14mm or 16mm. I would prefer to replace the entire piece from coupler to tank but would have to drop the fuel tank or remove the truck bed. At this point I cannot tell if the line is 3/8, 5/16, or something else. So before I cut the line I would like to know what to order. Does anyone know which fuel line size kit I should order? Nearest Ford dealership to me is over 30 miles away.

Any help is appreciated.

 

What if you called them and asked if they had that line and what size it was if you decided to replace it ? They might just provide you with the answer.

 

Thanks Hanky,
Had crossed my mind but did not expect much help from dealers. So I called the nearest dealer and seems I have to purchase all 3 lines as a bundle, $195! And they said it would be available in two weeks.
So I called another dealer who is at least 2 hours away and he confirmed my the bundle purchase. But he could get the part in one day! Neither dealership could tell me the line size. Look as if I'm going to have to find a local shop here I can trust, have it towed and have them drop the fuel tank and replace the line. Can't drive it since fuel sprays everywhere.
Still may visit another parts store before I go through all that. Maybe I'll get lucky.

 

Your luck is running strong if fuel spraying out has not caused any fire problems with a hot exhaust.

It can be a tough job either way and there are all types of line available easy to form and already made up to match the fittings used, IN MOST CASES.

Depending on just where the connections need to be made can become problematic.. Lets hope the shop you choose has the experience needed to do this job right and be safe for you at the same time.
