I had a Tee in back of block bad plan it leaked. I appears not all 350 blocks are tapped above the oil filter. Anyone have Ideas how to hook up my 2nd Mech guage.

Unless you really want 2 gages, you can block off the fitting over the filter. I think it was added later for a oil pressure switch to kill the electric fuel pump if it sensed no oil pressure.

That area is not tapped on my 69 300 HP pass block, or two pass blocks I looked at today, The four truck blocks I have are all tapped.

You can plug it with no problem created. 3/8 pipe plug I believe.

What was wrong with the tee on top of the block? I have done that several times with good results. It sounds like you may have just had a bad fitting. I would try it again with new fittings properly sealed on the threads.

I really want two guages just need to figure out where to screw in the second one. MY block is NOT tapped above the filter. Additionally it is not tapped in timing cover area.

I suggested the same a while back on here and Don Acardon said vibration would crack it and it appears he was correct.

Why couldn't the leak at the T be fixed. A T shouldn't be any different than a straight fitting. I have heard of a long pipe with a T on the end will often vibrate enough to brake the pipe. Are you using copper or plastic. You could put a T in the line from the block fitting, which would cut down on vibration at the engine.

you could get stainless steel fittings from mcmaster-carr. I too have never had a tee in the top of the block crack. Just out of curiosty why do you have to have 2 oil press gauges?

One SW under dash plus OEM idiot light.
that's what I have. I got a stainless steel 1/8" pipe nipple 2" long and added a brass female tee on top. been that way for years. works great.

I just talked to my buddy at auto parts if I use a BW S320 sender I can reduce my height 1.5 inches which allows me to remove a 45 degree fitting, Bottom line reduce weight less vibration issue.
