benett oil pump(suntec
i installed a used furnace.when i fired it up it blew the seal(suntec av2a 7116).originally it was a 2 pipe system.my service guy said i didnt need 2 so i stayed w/one.since the pump ran before and was in good shape,i cant figure why it blew.i dont want the new one doing the same.(the only thing i changed was an inline check valve).the manufacturer of the new one says it should be fine.im real shaky !!!!!
any ideas???joel

You forgot to remove the bypass plug.

The bypass plug is internal to the pump. You need to remove an external plug (usually from the return line port) to access the bypass plug. You then replace the external plug.
It would help if you told me what brand and model pump is installed on the burner.

Furd,
You are absolutely correct in your advice. BTW, the pump is a Suntec A2VA-7116.
He will need to remove the hex plug on the bottom return port then use a 5/32" allen wrench to remove the by-pass plug then reinstall the hex plug.

Joel,
I did manage to find the shaft seal but in nearly 25 years in the trade, I've never replaced one. There may be specialized tools involved. If you want to try, you can get the seal here: Patriot Supply - SP-367
As Furd suggested, the #2 Permatex is exactly what I would use.
