Question about 2004 Chevrolet TrailBlazer

Fuel leak and gas smell

We have been smelling a gas smell for  a few months. When I looked under the hood I found a small cylindrical device on what looks like a fuel line. It was slightly wet with gas. I wiped it off only to have the wetness return rapidly. Fuel is not running out it is just ever so slightly wetting the little cylinder. What is the cylinder and how do I fix it? Thanks

    Thanks! We looked up our engine online and it is a fuel pressure regulator  so we ordered one and the darn thing is not so cheap $109.

Small cylindrical device? sounds to me like a fuel filter and i would get that looked at A.S.A.P . or go to autozone and pick one out, there usualy about 20.00 two connection ports hold it in and it is easy but becarefull because those have pressure in them and it may injure you.

You are describing the fuel pressure regulator...yes could be leaking...the fuel filter is traditionally under the car...(drivers side) several inches in front of the left rear tire, even if old probably not leaking or releasing the gas smell...

My 2005 Chevy Impala smells gasy when ever started and sometimes after idling for awhile.


SMELL GAS YOU NEED CHECK ALL FUEL LINES UNDER THE HOOD IN THE ENGINE COMPARTMENT.IF GAS IS STRONG UNDER HOOD YOU DONT SEE LEAKING FUEL LINES.YOUR FUEL RAIL FUEL INJECTORS LEAKING OR FUEL PRESSURE REGULATOR O - RING OR DIAPHRAM LEAKING GAS.IF FIND NO LEAKS UNDER THE HOOD CHECK FUEL LINES UNDER CAR FROM ENGINE TO FUEL TANK FOR LEAKS.IF ALL IS GOOD YOUR EVAPORATIVE CANISTER SOAKED WITH GAS OR YOUR EMISSION EVAPORATIVE SYSTEM NOT WORKING. DEALERSHIP HAS TO CHECK AND FIX.

I have a 94 grand prix se 3.1. When i first start it ir smells like gas. It goes away and then comes back at red lights..... I cant find any leaks... Any ideas?


It may be the fuel pressure regulator located on the fuel rail on top of the motor it leaches out a very small amount of gas when they start to go inspect it if it looks even a little bit wet replace it, if this is not wet then the gas cap may not be venting properly replace it.

My 1993 chevy luminagets lousy gas mileage,when it runs you smell


. If you are in the car driving and smell fuel, chances are the leak in FRONT of you under the hood, probably being drawn in, by the heater or a/c. Open the hood and look for WETNESS. Don't see or smell it. Get UNDER the car ( safely ). Look around at the fuel lines. You'll find if you look. Hope this helps
