Just a quick question for you all. Recently got my injectors cleaned/fixed at a garage who I go to for most of my work (that i cant do solo). Been noticing an increasing fuel smell whilst driving so... been checking and keeping an eye on it. Noticed today that the small fuel hose part under the rail (about 5cm long) above the 5th cylinder has a serious leak. Whilst the system is pressurized it has about 2 drops a second falling from the drivers side clamp. Im not going to drive the car - getting it towed and fixed tomorrow (their expense) - I'd do it myself but i dont have any clamps/hoses at home. So not so much any questions I guess, but with that amount of fuel leaking (at idle) how much damage could this have caused if i hadnt picked up on it? Im paranoid now that my car is cooling down in the drive way and will burst into flames. Lame. I'd have spit chips if it had caught on fire. Good thing I have an extinguisher in my car Anyone else got leak experiences? Andy
My Z31 had a leaky injector that I didn't pick up on until it was too late. I was at a mates place and I found a relativly slow leak, figured I'd baby it home then get it fixed up as my pay hadn't come in. On the way home I was stopped outside a shopping centre and I noticed a bubble appearing on my bonnet, then a small amount of smoke from the engine bay. Popped the bonnet to find my plenum on fire. I managed to steal a bucket of water from a nearby car wash and was chased through the carpark by the manager who didnt understand why I needed the water. Was fairly easy to put the fire out. I had to replace my injectors, fuel rail, all wiring near the plenum, a bunch of hoses, coolant overflow bottle, windscreen wiper bottle and brake fluid canister. If I were you I'd be mopping up any spilt fuel and dont start it. If you can reach I'd also be taping up where the leak is to prevent any from coming out while sitting as an extra precaution. Possibly release the presure in the system by undoing the fuel filler cap too. Put the car in the shade if possible (push, dont drive). Dont ever under-estimate how easy fuel fires can start and how much damage they can do.
Tighten the clamp.... Get a screwdriver and see if you can tighten the clamp. More than likely that will solve your problem.
You are such a bitch (no offense to female dogs!). As zx299 mentioned, more than likely needs the clamp(s) tightened, not a difficult job. People should check their fuel clamps at least annually. Mine has leaked from that location before, so has a number of other Z's I have worked on.
Thats what I checked first when I noticed the leak. Shitty thing is.... The bolt in it turns, both ways, without getting any tighter or looser. Already looks like it was tightened so much that the clamp has cut the hose, hence the leak. *shrugs* else I would have done it myself.
8mm EFI hose from Autobarn/Supercheap will solve your problem. As long as the thread of the tightening screw isn't damaged, you can just re-use your old clamp. Pro tip:Use the open end of a 10mm spanner to push the old hose off the hardlines. Easy peasy, and no scratching. Just make sure you have plenty of rags around to catch the spilt fuel.
