95 Fuel Lines, Need diamaters HELP

I am wondering what are the diameters of the fuel lines on my 1995 Pathfinder, I have to replace a section of the fuel line, I believe it is the feed line. What is the outside diameter of the feed and return lines? I am thinking about cutting the section with the hole out and replacing it with rubber fuel line. If anyone could help it would be much appreciated

Can't I just remove the efi fuse and start the car until it stalls then turn it over a few times to relieve pressure? If someone could just tell me what the diameters are it would be helpful. Thanks.

Well the lines are attached to rubber fuel lines that come from the fuel pump so rubber fuel lines replacing the metal ones should hold as long as they are clamped ok and the remaining fuel line is strong enough and doesn't collapse when clamped.

Yeah, I will make sure they are all good. Now if anyone knows the dimensions of the lines just tell me. I don't feel like taking the tire off again and breathing gas fumes while I measure, I already have had enough gas fumes for a few years at least.

Well I was going to replace just the part of the one fuel line that is leaking but I called up a Nissan dealership to get prices on all new fuel lines. I was thinking new fuel lines from Nissan would be some ridiculous price. The guy said he had a set in stock and they were originally 103.00 but would cut me a deal for 73.00 for all three lines. After thinking about it I am just going to replace all the lines since the originals are not in good shape and I would probably spring another fuel leak not long after fixing this one. Later.

Well after 5 hours and alot of gas fumes the fuel lines are fully replaced. It was a major PITA but had to be done. The longest part was removing the old fuel lines because they are attached to the frame raill in about 6 places and brake lines run along with them so I had to be extra careful not to snap them. When I took out the old lines I used a bolt cutter and cut them into smaller sections so removal was easier then snaking them out. Putting the new ones in was pretty time consuming. I started from the front and snaked the lines down to the back. I had to push them a little from the top and then get under the Pathy to guide them into place. After about what seemed like going back and forth 100 times they were as good as they were gonna get. I started it up and no fuel leaks. To get the rubber hoses off the old fuel lines I pryed the rubber up a bit with a flathead and sprayed thrust between the line and inside of the rubber, after much twisting they popped off, and the new lines slid in pretty easily. I still have to attach the lines to the frame rail but other then that it is DONE. Later.

Good job 95Finder ! Sounds like you took the right approach and fixed everything, rather than a quickie fix. Not that quickies are not appropriate sometimes, but when it comes to fuel, hydrolics, or electrical, you are asking for it. I can sympathize with your solid line adventure; I replaced the hi-pressure power steering pump line in an old Nissan 720 pickup. It wrapped the entire engine compartment/front frame cross member with only 6" of flex line at one end. I kept removing more and more parts, day after day because I would get so frustrated I had to walk away from it. I finally got it in through the passenger wheel well, bent it to get it around a 'corner' then bent it back and bolted it to the frame. It ranks in the top 10 of PITA jobs I have ever done on a car. Again, well done... :clap:

Yeah, it is definately a PITA to run lines that don't have much flex to them. Today I just used zip ties to attach the lines to the frame rail and also zip tied them together. It seems like the old mounting brackets had something to do with the line rusting through, I believe they trapped moisture against the line and caused it to rust out faster then the other parts of the line not in contact with the mounting brackets. I got them nice and snug up to the frame rail, hopefully they hold. If not I will just buy some stainless steel braided fuel lines and run those up, now that I think about it, that probably would have been alot easier and cost about the same. Later.
