I have a 93 one ton and I'm attempting to remove the metal injector line that goes into the IP. I've got a small leak and it's time to replace it. Do I need any special tools to get the metal fuel line off. I noticed there is a small nut that holds the line onto the IP, what size is that? And there seems to be two small nuts that hold the line together in the middle. What would be the best tool to use to get inbetween the metal IP fuel lines. Something skinny, and strong, Does that have a special size?

Thanks for the help

 

If you are talking about the line that attaches from the top of the IP(near the front) and bolts on to the engine near the filter, it will snake out if you pull it towards the radiator. I wouldn't mess with the middle compression fitting. Mine had that compression fitting and I thought is was some junk the PO did.
If we are talking about the same line, it is real easy.

 

pretty simple as long as it is not seized in the adapter at the pump like mine was. The PO had twisted it like a pretzel then left it there. I had to cut it in half to get it out and replace the line.

Use a line wrench, a crowsfoot one might be handy. Don't remember sizes. Just a reminder anything on the engine is metric.

I believe the fitting is a 14mm the ones i've seen have all been seized to the line by paint and rust. use a brake line wrench and an open face wrench on the reducing fitting on the bottom of it for a back up. The line bolts into the top of the fuel filter with a banjo fitting with two copper washer so watch the copper washers when you loosen it.
