Fuel Pressure Regulator O-ring
 

Is this thing serviceable? I called Toyo and they said that the regulator itself needs to be replaced, which I find ridiculous. I just need to replace the o-ring between the lock nut and the regulator.

just go to your local seal shop that sells o-rings, gaskets etc and show them the o-ring.. they should be able to find one for you

Yep...Carquest (of which I work for a year) has a box with about 50 different sizes. NAPA, Pep Boys, etc should also.

Thanks guys. Upon closer inspection of the regulator, I saw that there were pinholes in the side, thus spraying fuel onto my engine as it was running... talk about a combustion hazard! Replaced it and hopefully no more problems out of it.

glad to see ya got it sorted ;)
