FUEL PRESSURE REGULATOR

I have a 2001 Deawoo Lanos Hatch Back that has been in the repair shop 2Xs already and now the mechanic says that the fuel pressure regulator is cracked and leaking gas. I have looked every where I can think of to find one but can't seem to find one anywhere. Can anyone assist me in finding one or give me some ideas on how to repair mine so the mechanic will release my car to me as soon as possible? If I don't have one soon I will lose my job and my car. I am a single grandmother raising my grandchild and can't afford to lose my job. Please help!!!!!!

Is it already in the shop now? He won't put another one on for you? They are not that expensive and he shouldn't charge you that much to replace it. Should be around $30 to $60 for a new one.

2001 PT cruiser dies going down the highway. turns over but won't start again. took out spark plugs and there was oil on the plugs???


The liquid on the plugs may be gasoline that looks like oil. If it smells like fuel then it's gas and it may indicate that you have a leaking fuel regulator.

A Fuel Pressure Regulator is a simple mechanical device that holds constant fuel pressure or relieves excess fuel pressure by way of the pressure compressing an internal spring and opening an orifice back to the fuel pump.

Normally on a Chrysler it is mounted on top of the TBI throttle bodies, on top of the injector, but if it's not visible there you will need to check a shop manual. If it is mounted on the motor (not under the intake cover) you can remove a rubber hose and see if there's gas in the hose. If there is, the regulator has failed. The hose is only supposed to have air in it at all times.
