Sentra 2005 Fuel Line

Sentra 2005 Fuel Line was created by WV591
I wanted to measure the Fuel pressure on my Nissan Sentra 2005, suspecting a low fuel pressure from regulator that was causing a P0171.
I tried every type of fuel disconnect tool on the market i could get my hands on and none of them worked. as you can see from the picture, the fuel line connect ( right side) sets too far back and can not be pushed in when using disconnect tool behind the lip.
After weeks of trying every tool, I gave up and just replaced the fuel pump which resolved teh P0171 issue.
not sure if NIssan uses a special tool or there is an issue with fuel line that can't be pushed in.

Nissan does have a specific release tool for those quick connectors. J-45488 is the OE tool, but Assenmacher makes a pretty nice equivalent:

If you can justify it, I highly recommend the 10-pc set (which includes 8026). You never need a line release tool, until you need one. ;)

Thank you, I hope I'll never need one again because I think something is wrong with that fuel line on right side. It can't be pushed towards the Lip, it won't budge. so I doubt if even Nissan tool will work. the time I ended up wasting on this fuel line..................

Maybe someone was monkeying around with it before you? :huh: I've been able to get those off using a small pick, way too much time and more than a few swear words.

If needed in the future, you can try using some brake cleaner inside the connector, blowdrying it with compressed air, and applying some penetrating oil. If you've tried all that junk, disregard. :silly:

Before buying the correct tool I fumbled around with the plastic cap of a ballpoint pen. Cutting off the closed end and also cutting open the long side allows to indroduce it and push on the retaining tabs/spring. I works "somehow", the tool is so much of a reliev.

I also often see an easier to handle quick connector further downline.

An expert is someone who knows each time more on each time less, until he finally knows absolutely everything about absolutely nothing.

I bought the car new back in 2005 and it only has 48000 on it. Unless it was a screwup at the assembly line which it is possible. but it has had so many issues in short times. that's the problem with cars not being built and parts not manufactured in Japan anymore or not even USA.they don't even use the chinese parts made for NIssan, and use cheaper substitudes.
my 98 camry made proudly in japan has over 250K and purrs like a kitten.
