#20 of 22 Fuel Leak
Jan 31, 2009 (12:35 am)
I have a 2005 Buick century and I can't turn on the vent because I have a fuel leak under the hood. Inside the car smells like gas. I was wondering if anyone could tell me how I can get it fixed,or if there's somthing that I can use to stop the leak???

Just had the same problem with the same car. If Im right, the smell will go away for the most part during constant drive time. When you crank up, the smell is strongest and seems to last for about 5-15 min before getting better. ANSWER- The diaphram in the "Fuel Pressure Regulator" is failing which will also cause the car to have a long start. The regulator is vacuum controlled and if i remember right, has to sustain pressure from 5-7psi. Not much. To be certain that its the problem, pull the little vac hose off of the top and smell the regulator hole. Smells like gas, its bad. Albiet, the gas will leak around the edges of the regulator. Its located on top of the engine, attached in between the fuel line and fuel injector rail. Hard to miss and not all that tough to change.
#22 of 22 PCV valve replacement

2005 Century, 4-cyl. My son went to replace the fuel filter and PCV valve; fuel filter went fine.
He could not do the valve because he said it is riveted in; is there a trick to changing it?
