I bought an Autometer 4763 gauge that didn't come with the correct fittings to plumb the sender into one of the extra ports on the back of the bowl. I went to the Ace hardware store right across the street and they didn't have anything (not surprised) and then Napa. They couldn't find a fitting to match either. He found that the plug threads are 7/16 20 tpi and the sender is 1/8" NPT. He suggested getting a 7/16 20tpi bolt, drilling it rifle-style, and then tapping it for a 1/8" NPT. The alternative, and what I ended up doing, was to use brass fittings to tee it off one of the supply lines to the heads. I ended up going that route but wanted to know if I should have looked harder for the right fitting.
Here's a pic of what I have now. I've test fit it, and it seems to work although I will need to insulate the hard lines because they rub due to the offset.
What he has there looks good and cheap too but will it fit in the space? And those lines to the heads are rigid and not very forgiving, I'd like to hear if that works.
Besides the lines being rigid, I doubt there's enough room for that to work...
This... I recently rebuilt the fuel bowl and I would not want to mess with the lines too much unless I was replacing them with flexible lines of some sort.
Why not use the test ports or whatever they are called on the side of the bowl toward the engine? There is a pre and post filter. I installed a 90 degree on the post filter port and it works great for the ISSPro sensor.
