Hey everyone. I have an issue with a massive fuel leak, that is pouring fuel off the engine. I assume the leak is comming from the fuel rail, but I was wondering if anyone had any ideas/tips as to how to check exactly where the leak is comming from? ANY ideas would be a great help. Thanks.

 

let it run, and watch? OH and have a fire exstinguisher nearby.

 

Everybody is a comedian. Trust me I've tried that one. It is comming from the passenger side towards the rear, around the fuel rail area. It's just hard to nail down from that point.

 

The most likley cause is the fuel pulsation dampener on the passenger side under the intake plenum. it is a round thing off the back of the fuel rail. It is very common for those to leak. you must remove the plenum to replace it.

 

I thought that maybe a possibility, but I didn't feel any gas leaking there when I tucked my hand back there. What I am worried about is having to pull the plenum off, replace a part/washer or whatever, replace the plenum/hoses only to find the leak wasn't fixed. So I am hoping for a tip to help locate the leak so I can fix it in one or two shots. Id there a way to have the fuel system run w/ the plenum off, so I can see exactly where the leak is?

 

I know this might sound really stupid, so forgive me, but if I was really desperate to find a leak I would just throw some baking flour or any powder to the area you think is leaking. The powder will get wet in the area leaking. Again forgive me if it does sound ridiculous but hey anything helps.
