 Posted: Mon Jun 11, 2012 6:07 pm Post subject: Fuel injector leak help? |
 |
|
Hey guys, so I got the car back from mechanic a couple days ago and since then its smelled like gas a little bit, I asked him about it and he said that it was just the dried oil around the engine from where he changed oil sensor
I should have checked it out then but I decided to today and I find fuel dripping from one of the injector directly onto the engine bay!
It appears to be weeping from the seal between the yellow plastic part and the metal plate. Can I replace the seal or will the entire injector need to be replaced and are these extremely hard to find?
Any help will be greatly appreciated

I have some spare injectors I can mail to you. But first I would get some 30R9 fuel hose and real FI hose clamps and do the whole car (5/16" hose works fine). It might just be the hose that is clamped to the injector, an injector leaking externally like that is rare.

| as far as stopping fuel flow when I change the hose. how would I do that, as the small braided line goes directly to a metal fuel line |

Only a cup or so of fuel should come out, personally I use a bunch of rags so I dont get it everywhere, if the car will be sitting for a long time with an open line I plug it with a bolt or line clamps.
The return line under the car is a bit different. You should clamp the line and switch it fast so you dont get fuel everywhere, because otherwise the tank could drain. |

| To answer your question yes you can replace the two seals but that looks like a leaky hose or a bad injector. |

That is a leaking injector. In hot weather...you would have gone crazy looking for that leak unless it was significant...because if you turn it off every time you go to look...the fuel evaporates so fast that everything is dry by the time you get back to the engine compartment.
That is a leak between the yellow section and the black section. They can do this from age...but the most common issue...if you live in cold climates...is from small amounts of water in the fuel line staying in the system and gettin ga hard freeze. It expands and pushed the yellow part away. I found this out on my first 411. It had a lot of water in the tank. It was my first car and I just didn't know what to expect.
We had a cold snap and it went down to about 5F. All four injectors cracked their yellow portions loose just like that and leaked everywhere.
