My '07 has developed a fuel leak on the nylon (?) fuel line that feeds the fuel rail. Has anyone else experienced this? Dealer wants $78.00 for the .50 cents worth of plastic fuel line. I've found a Dorman repair kit for $20.00 but not sure if that is the way to go or not. Anyone have any experience with this repair?
See photo- yellow circle is the complete fuel line- red circle is where it is leaking from.

get the OEM part and fix it right.

I've used Dorman products for years and have had very good success with those I've used. Most have lifetime warranty..OEM not usually. I've used their seat heating replacements in Fords and Mercs without any problems. I've used their power window regulators in Mercedes without problems. I've used their front and rear upper control arms in Honda CRV and Civics. I've used their canister evap solenoid in Nissan and never had an issue. Never used their fuel line that you need, but if I needed it, I'd sure give it a try...especially if it has the lifetime warranty. Like you discovered, their OEM spec parts are usually 1/3 to 1/4 the price of the dealer, even with a trade discount.

It appears that the leaking fuel line section is actually part of a large "assembly" of fuel line pieces that are made of various shapes of nylon tubing that are connected with couplings that are heat fused together. The end that connects to the fuel rail has a standard plastic quick connector but the other end attaches to a coupling thru (what I have determined to be) a heat fusing process of some sort? Even if I go with the OEM part it looks like I will have to fight with making the splice connection on one end. If I do the repair I will have to fight the splice connection at both ends. Some research I have done suggested boiling the tubing to make it softer and heating up the metal coupling part so they can be slipped together. Once cool they have a positive leak free seal.

Seems kind of sketchy having plastic fuel lines in the engine compartment that would melt instantly with the smallest under hood fire turning it into a large fire quickly :eek_surprise:

My local dealer ordered the part for me so we can take a look at it tomorrow and see what is involved in replacing it. My parts guy is pretty cool- ordered the part with out me having to pay for it or having to commit to buying it. He even order some additional parts because he was not sure exactly which part it was (from the crappy Nissan parts diagram).

can`t go wrong with them doing the repair, they assume all the responsibility and warranty the repair.

Ok so none of the parts the dealer ordered were the right. Parts manager wants to call Nissan on Monday with the vehicle VIN and photo of the part to determine what the correct part number is- UNBELIEVABLE! In the mean time I started looking further into the Dorman repair kits- nothing listed for Nissan just GM/Chrysler and Ford. So after several trips to the parts store buying different kits I finally got something that works...

Ended up getting the 800-057 repair kit and the 800-191 press fit union. The quick connector on the repair kit fit the Nissan fuel rail perfectly and locked on securely. I did not use the barbed splice coupling that came in the kit- they are about impossible to get pressed into the nylon fuel line when you can not get the piece of fuel line you are working on off of the vehicle to work on it. There are various instructions on Youtube showing how to install the splice- boiling water, heat gun, bench vise/hammer- none work well without having the part off of the truck. So I used the press fit union- the guys at the parts house assured me they have sold tons of them without any issues. So $30.00 later and a day of my time and my T is back on the road. With the correct parts this repair would have taken about 30 minutes. Hopefully this thread may save someone else here on TT alot of time and $ if they have a similar issue with leaking fuel lines.

Note the Sharpie cap used for removing the OEM quick connector from the fuel rail- got that hack from a member here on TT (sorry I don't remember the members name and can't find the thread). No local parts places had the $20.00 Nissan/Toyota tool in stock- the Sharpie cap worked perfectly!

:cheers:

You should be fine with that. I had the same issue with a Ford Ranger fuel line, no OEM replacement could be found and the Dorman kit set worked perfectly......and still is 8 years later.

 

[Pale Rider]

looks good! any issues since the repair?

 

[ArmAir1]

No problems working fine.
