Another fuel leak!

[Daveo91Burb]

Parts stores usually carry an universal kit with different sizes. I just had to buy some for my other suburban. If threads are npt style then they do seal on threads, if fitting has oring or angled mating surfaces then the threads play no part in sealing.

Thanks, I found a variety pack of viton at the parts store tonight. Yeah, the gauge and pipe plug are NPT threads - definitely need some sort of sealant.

Got everything hooked up and sealed and ran the pump twice for about a minute at a time. No leaks - good news. Thanks for the help.
