01 V6

Coming off the top of the sending unit are two short S shaped plastic lines. Feed and return. Quick connects on both sides. About 6 inches long each.

I need to replace them. I want to do it next weekend but if I order the parts from the dealer they won't be in on time and they are also a little pricey.

SO my question is can I just replace them with rubber fuel line and worm drive clamps? Maybe run the line a little long to prevent kinks while routing them?

Or do you recommend that I wait for the right parts?

Thanks

I would recommend using the correct parts. However, if you choose to replace them with hose and clamps, make sure you use fuel injection hose and fuel injection clamps...and not regular fuel hose and worm gear clamps.

I don't think I would trust fuel under pressure in the engine compartment, with a jury rigged system. To get home in an emergency, with a quick fix, is one thing. Just my opinion, I also would check Rock Auto, I just replaced headlight bulbs, and they were here in 2 days, with standard shipping. Good Luck.

He's not talking about the engine compartment; he's talking about back at the sending unit. Even still, fuel injection hose is used in the engine compartment even on this vehicle, however, I also agree that it's best to stick with the correct parts when possible.

My bad. And I always say reading is a skill. That being said, my 2002 just had the fuel sensor replaced, under a factory recall. Just had it done in December. I'll look for the link. Here it www.nissanproblems.com/recalls/Frontier/2001/

Yeah, I had the same thing done last year after I bought my 2003 Frontier. I went to the Nissan site and checked for recalls. I still had open campaigns for the fuel sender and the steering column shaft. Even though the sender had been replaced with an aftermarket the previous year, they still replaced it.

I know about the fuel sender but what fails on the steering shaft?

The U-joint in the lower shaft would rust and cause the steering to bind.

I ordered the two lines from the dealer but I'm going to yank the bed this weekend and replace them with rubber fuel line for now. Have to do something, I'm leaking fuel pretty bad and it's my DD. Looks like I'll be doing the job twice.

Oh well I have to clean and paint the underside of the bed and frame rails anyway

Just remember to get rubber "fuel injection hose" and not regular, rubber fuel hose. It should be 8MM (5/16").

I used Goodyear fuel hoses on my truck (2002), with t-clamps, not worm clamps, to get it running. It was a temporary fix, but I got lazy and never dropped the tank to intall the OEM ones I ordered. It's been about a year, and the goodyear lines are still good, no cracks or signs of leaks.

Not saying they're better than the OEM lines, but it's a good alternative if you don't have the oem lines readily available. Just stay away from worm clamps. I used worm clamps the first time and they couldn't hold the pressure.

When I got the bed off the leak ended up being from the sending unit assembly. There's a small crack on the plastic 90 degree tube for the feed, JUST before where the plastic quick connect line goes on the top of the sending unit. The plastic is old and brittle

All I had was the new feed and return quick connects - I assumed that's where the leak was before yanking the bed so I bought those

Couldn't get a sending unit on short notice and since this is my DD I had to run it. So I JB welded the crack very generously, slapped the new feed and returns on and she's not leaking at all. Temporary fix or permanent?

This was a few weeks ago

I'm contemplating on getting a new sending unit now. Dropping the tank is no problem for me but I just don't know if it's necessary at this point

I'm surprised the truck was still running good with the the feed line leaking so much. It was a steady spray. Must be the walbro pump that saved me haha.

I'd say temporary. When it comes to the whole sending unit, i'd replace it all just to be safe. If it's old and brittle already, the whole thing will probably fail. I had the same thing happen to my sending unit. I was changing my fuel pump, and as I was disconnecting lines, the plastic around it just cracked and gave up. I had to replace the whole unit, the fuel pump, connectors, and the lines.

If you decide to replace the unit, make sure you get the right one. I cheaped out and ordered one that wasn't even close to fitting and it made things take twice as long. Also, have some extra lines ready, the ones that go from the fuel pump to the sender. Mine were old, and of course, disintegrated as I was taking them off.

Maybe that JB weld can hold until you can get all the parts in. My truck isn't my DD, so I had it sitting for a week or two with the tank off. But once you have all the part ready, it's not that bad.

One last thing I'd throw out there, be careful with the power connector that goes into the sender unit. Long story short, I accidently cut it as I was taking it off, and I didn't see it, so naturally when i tried to turn on the truck, it wouldn't start. It took a lot of toubleshooting to find the split wire because I thought it was just a clogged line or something.

RockAuto.com is your friend.... & fast shipping WITHOUT charging an arm&leg

Rockauto doesn't have the lines nor the sending unit

did you look at other years that are part of the same generation? I have found I often have to be 'creative' like that on RA.com (unfortunately) BUT it hasn't failed me yet (3 different vehicles)

IIRC, I ordered the sending unit from Amazon. I'm not 100% sure, but I think the 4 cylinder and 6 cylinder sending units are different. I bring this up because I went to the junkyard and pulled 2 sending units, and they were both incompatible (the trucks had no engine, so I couldn't tell they were 4 bangers). I did a quick search, and both trucks were 4 cyl, mine is a 6 cyl.

The rest of the hardware, I had to order from Nissan.

I just got the whole sending unit including a new Temp sensor and OEM gasket and bolts from Amazon for $55.

as far as using your own hose and clamps. you can easily do this. I have my own fuel hoses on mine for 6 years now and now leaks. Now if you just cut the metal line and slip on a hose it will eventually pop/slide off since there is no "ridge" on the metal line for the clamp to "hook" onto. so what i did was i used my brake flairing tool to flair out the end of the metal line just enough so the hose will not slip off under pressure. since i already had this tool and hose on hand this was a free fix for me. If you dont i would just order new Fuel lines
