I agree with you 100% about getting as much info as possible before changing/replacing parts, those are great suggestions. As far as getting some temp readings, do you think pointing the laser style temperature gun at those components will be accurate enough? If not then how do you suggest I get those readings?
My engine is LOUD, I can almost guarantee I wont be able to hear any fuel boiling even if I tried. Is there any other way for me to check if the fuel is boiling?
