I ONLY does it durning hot starts, so unless it gets worse, I am not going to bother.
But in the event I do, where is it located and how do i do it?
Thanks,
Unfortunately it's not so easy. If it's leaking, that's what causes your hot restart problems, and while you're driving it's dumping extra fuel into the intake. Your mileage is probably suffering to some extent because of the leaking regulator. I would replace it as soon as you can to prevent damage and maybe get better gas mileage. It will only get worse as time goes on if you leave it.
The FPR is a small canister on the fuel rail that connects to all the fuel injectors. If you remove the cover from the top of the engine, you will see the metal canister with a small vacuum hose connected to it. It's on the driver's side on the rear of the fuel rail. All you have to do to test it is take off the vacuum hose and start the engine. If you see fuel leaking from the metal vacuum nipple, the FPR is bad and needs to be replaced. When mine went, it wouldn't leak unless the vacuum was attached. To replace it, you just have to remove the clip that holds it in there, lift it out, drop the new one in, put the clip back in, connect the vacuum line, put the engine cover back on, and you're done. It's extremely simple to do and well worth the time and effort.
