Re: 01 gc laredo hard starting...help please
This is indeed the o´ring i previously mentioned. I only don´t understand completely why this o´ring would make starting harder, since the filter/pressure regulator should keep the pressure in the line from the regulator to the engine.
But if the problem would be with the o´ring, you could change it yourself if you are a bit handy. You have to lower the tank for that, so its a job of several hours. I lowered the tank myself once and i think that you can count on 5 to 6 hrs job start to finish.
