ok after driving the jeep when you turn it off it smells like gas on the out side of the jeep by the engine bay what could be causing the smell thanks for the help

 

i have the same problem but i think its my cat

 

I had that same problem several monts back...after looking and sniffing around ...it was the fuel pressure regulator, it was leaking from a bad o ring. Hope that helps!

 

where is that any pics

 

I have the same smell.....I'll check it out.

 

here are a few possibilities:
1. Fuel pressure regulator has a leak form an o-ring
2. there's a crack in one of your fuel lines and fumes are escaping.
3. an injector o-ring is bad.
4. bad cat converter

 

also a possibility listed in the Haynes Repair Manual is that your evap. emission canister could be clogged. Don't remember what years have it though...some of the earlier years have the EGR system. Also I have no idea where you get a new filter for the canister and what not....If you pick up a Haynes or Chilton, there is a section with a list of symptoms and possible causes for the symptoms.....

 

Ill put a pic up tomorrow.

 

my 99 xj has the plastic tank and on it is a large screw cap that allows acces to the tank and pump. check with a screwdriver and a hammer to make sure its tight

 

Here's a couple pics of the fuel pressure regulator. It sits right up front..on the rail with the fuel injectors. Hope that helps.

 

5. One or more of your fuel injectors is leaking.

Recomendations:
A. Check to see if any of the injectors are wet after driving.
B. Keep a fully charged fire extinquisher mounted in your Jeep where you can get to it quickly.

 

where are the fuel lines in the engine bay

 

Ummmmm...errr...duhh....all over the place. lol you have them at your fuel rail, your injectors, fuel pressure regulator..ect

 

step one if you smell gas you open the hood and look
