that be it, thank you! RR

 

[Rapid Robert]

after more thought if I just have a bung welded in to the pipe do I screw a bolt into it to keep it from going out of round from the heat? & I understand you want the AFR sender tip in the pipe to be pointing down a bit??

 

[furrystump]

I have welded in two. Never threaded anything in them. Yes, the tip of the sensor should be lower than any other part of the sensor. So water will drain out and not back into it.

 

[Rapid Robert]

OK I will have the tip lower. One time a guy welded in a larger than this bung into the oil pan (class rules for crank inspection) & afterward the plug would not fit

 

[dano]

I've welded them too, I put a plug, bolt or old sensor in to prevent splatter from getting on the threads. This was MIG welding them in.

 

[Rapid Robert]

I will do

I have one that welds on. You can have it for the ship.

 

[Rapid Robert]

Dave that sounds more than fair, I will PM

same thread as a spark plug chasing tap. use an old spark plug to help with splatter.

^^^ I will do exactly that
