Easy guys,

 

started my car earlier today, smelt a bit of fuel inside the cab, I thought I inspect it and discovered a tiny leak, just wondering whats the best way of sorting it out is? the metal line seems fine, and rubber seems ok and doesn't look deteriorated and clamp is tight too yet the fuel was dripping.

Check page 2 for lovely diagrams and pics etc

change the hose with new and a new clip. the rubber has probably gone hard. common problem with these cars.

 

also check the fuel hose at the front of the engine looking between the plenum and the throttle linkage, the pipe joins the two sides of the fuel injector rail, they leak there too, its a bitch to replace!

I've heard about the hose between injector rails, I've not checked it but hopefully it wont need replacing because I believe you need to remove the plenum for it and I'm not doing that in the winter lol

 

in regards to current leak, do I need a specific fuel hose? or does it has to be one from Nissan? to de-pressurise the fuel lines before changing the rubber line, I was thinking loosen the fuel cap and start the car and remove the fuel pump fuse/relay and wait for the car to cut out, would this method be ok?

 

sorry for the newbie questions, I rather do it right the first time than end up creating more complex problems lol

Any rubber hose will do as long as it's rated for fuel. Ebay is loaded with them.

 

As for the de-pressurising, your pretty much spot on but take the fuel fuse out before starting the engine. Turn her over a few times and your done.

You want 7.5mm EFI (higher pressure fuel hose). Replace the 2 short hoses at the filter, the longer hoses that run to the fuel hardlines on top of plenum and shorter hoses that run between hardline, Fuel Pressure Regulator, injector rail and Fuel Dampener.

 

Ideally, you will also want to replace the already mentioned hose between both injector rails. Yes, it requires upper plenum off for access. Old hoses will often be quite difficult to remove. Loosen the clamp sufficiently to slide it back (exercise caution to not loosen too far, as the lower nut section of the clamp will fall into the plenum runner abyss) and use a stanley knife to cut the hose from the hardlines.

 

OEM SS hose clamps are more than adequate for re-using, and often, even after their age, a much better alternative than worm drive clamps. Have personally been doing so for the past 11 years without issue.

Yeah, sorry I should have said "high pressure".

pm me your address mate and ile send you the correct pipe and length for your needs as i have a bit left over...put the pipe into a cup of boiling water and it slides on real easy when you come to do the job;)

Fuel pipe posted 1st class this morning mate...good chance it will land on your mat in the morning.

Thanks Brian, much appreciated

 

will let you know how I get on.... fingers crossed that I don't find a leak between the injector rails.

if you do then its an easy fix with plenty of coffee and fags LOL...ive put extra in just incase;)

unfortunately I stopped smoking 6 months ago so now I have rely on sheer will and I doubt coffee on it's own will suffice lol, I recieved the pipe today mate, much appreciated, will give it a go fitting it tomorrow :)

goodluck Sascha:thumbup1:

You can do the hose between the throttle linkage with out removing the plenum, you can basically hack the old pipe out with a flat bladed long screw driver, the new hose cut to size, use something to wedge open the throttle linkage, then (as znut says) dip in boiling water, and using long nose pliers, slide it on passenger side first, then drivers side (with clips already on the pipe lol)

 

It will only go on one way easily, i found out the hard way trying to bend the damn hose once it started going cold, but if you struggle to get it on, then take it back off and do it the other way round. it isn't as bad as it seems, the biggest issue i faced doing that, was getting the old hose off, and not figuring out that it goes on easy one way, but if you put it on the wrong side first, it takes bloody loads of faffing about.

 

But im pretty sure if my memory serves me correctly when i did it, its passenger side first, then drivers side.

 

I mentioned using long nose pliers, as this would definitely make the job easier, but i did it with out, using just me pinky's

best way i thought was to cut in half and then cut along the pipe with a craft knife and peel them off...did,nt jeff do a thread on this paticular job Ian?? its out there somewhere.

think he did, i remembered seeing something along those lines, when i was doing mine, didn't have a craft knife to hand and i was buggered if i was going to pack all me tools away to go rummage around the house for one, so ended up using a flat head screw driver lol.

 

P easy job once you know how.

I have replaced the pipe by the filter, Thanks Brian for the pipe

 

now in regards to the pipe between the injector rails, it doesn't seem like it's leaking but I could smell fuel from that area, but tbh I had fuel all over me, I ran the car for a bit keeping an eye on that area and seems fine.

 

what I did find was quite a few of the clips on other section of the fuel lines weren't very tight, is that normal?, when I replaced the filter side pipe I gave the clip a good tightening, I found the other clips weren't as tight... wondering if its cold causing contraction in the rubber, then again the car is garaged, but the garage don't have heating so does get cold in there I'd imagine.

Its very common for a fuel leak between the injector rails and the clips are the culprit they just need a good tighten.

I have removed the plenum cover to keep an eye on that pipe, this will be hard cause I barely drive the car :/

 

also is it possible to remove the throttle linkage and cable? because the pipe sits right under it, if its possible to remove that then there is no need to remove plenum

Its very common for a fuel leak between the injector rails and the clips are the culprit they just need a good tighten.

 

This advice although sound on a new bit of hose, can create a bigger leak on an older bit due to clip cutting into the harder hose and creating a larger hole. as what had happened on artztogos when i checked his fuel leak. the clip had been tighted that much to stop the leak it had actually created a new one by splitting the hose in half.

 

So its advisable to actually replace the hose and clips.

Vodkashots. I have no idea how you managed to change that hose without removing the plenum lol, I can't get a screwdriver in there to tighten the clips let alone remove and put a new one on, I wonder if you have any fingers left at all lol

easy mate, have you wedged the throttle linkage open? that is very important, you need the clips either already on the metal pipes or even better, already on the hose, tighten them just enough to stop them moving about with the screws facing up, put the hose onto the pipes, the undo one clip at a time and move it into position, then start tightening it up.
