'86 Jimmy 4in Lift, 40’s, tons, 8.1 Swap- 700r4 said PNNNNN

This is not a dedicated trail rig, but does trailer to the destination usually. I am currently in the planning phase of doing a 52/56" spring swap, and getting back to being more road worthy.
Now that I look at it. On the other side of the housing there is a bolt plugging a port. I may just use that one.
 
Are you referring to the plug which is sort of under where the upper hose runs?
That one is 1/2" pipe, so you need a bushing. That can push the sender up and make the electrical connector hit the radiator hose. Can I suggest that you mock it up before you install the intake??
Then if you don't like how it works, you can tap the port without worrying about shavings in the coolant system.

I do believe it’s an optical illusion. The hose exit is further forward than that port, but I’ll grab a better picture.
That spacer you stole off of you brothers truck looks like a factory Dodge piece
That’s kind of what we mimicked, but made the inside diameter larger to fit over the 14 bolt hub, yet small enough to mount a Wheel over.
 
I know that the hose runs forward of that, I have the same intake. I am just saying that it isn't a great fit there. I drilled mine.
 
Yeah no crap.

So with a 3/8 thread, it uses a smaller bit correct?

As you can see, I don’t drill and taps much.

First, yes, use a smaller bit. Or you won't be tapping it.

Second, 3/8" NPT is 3/8" (nominal) inside diameter, outside it's about 9/16".

Use a chart like this one:

And if in doubt, step the size up gradually until you're certain it's right.
 
@campfire that's a good explanation!
And I am not surprised that you know where to find info like that. :waytogo:
I always measure the starting end of the tap, then go for my pilot hole.

And just FYI , a buddy of mine bought the HF tap set. He says that even with cutting oil, they usually are dull after one hole.

Uhh...Thanks! :blush: :blush: :)

Yes, measuring the tap is a sure-fire way to get you in the ballpark. But if you drill out just barely enough to shoe-horn the tap in there...you'll be cutting through more metal than necessary. Dulling the tap prematurely.
