Default FUEL SMELL PROBLEM!


Hey...I thought I had this all taken care of but the gas smell has returned. I checked one of my vacum hoses under the hood and gas dripped out, why or how this could be happening. Also my start up is getting rougher. Any suggestions would be greatly appreciated.

The only hose where gas would come from would be the fuel pressure regulator on the fuel rail...that I could think of. This will also cause it to start and idle rougher.

COULD A PIN HOLE IN THE HOSE LEADING TO OR FROM THE FUEL PRESSURE REGULATOR CAUSE THE SAME PROBLEM?

If you are getting raw fuel in a vacuum hose there is something wrong. The hose should be clean on the inside. The fuel pressure regulator is a diaphragm device. On one side of the diaphragm is fuel pressure and the other side is engine vacuum. The two should never come in contact with each other. It is possible to have a rupture is the diaphragm allowing fuel to escape into the vacuum hose.

this exact same thing happened to my 1994 mazda 626. it had horrible idle speeds (varying each day) and the start up was horrible. I took it to the dealer and they said that they couldnt find out where the gas smell was coming from, why it was idleing bad, or why it was so hard to start up. my dad and i opened the hood and the first thing i found was that gas was leaking around the fule pressure regulator. we got a new one and it solved the problem. (apparently the disc was cracked on the inside)

An update on my Fuel Smell Problem...after the install of the new fuel pressure regulator no fuel smell, the car starts right up but now it seems to be missing terribly...very sluggish ride. Any suggestions!
