I was going to tap my boost gauge into the crossover tube but I can't figure out how you get the thing off. I took the 4 bolts out of the base on the intake side and loosened the coupler on the turbo side but it wouldn't budge at all. I couldn't find the plug people talk about on the intake to plumb the boost gauge too so I was just going to tap the crossover since one of the fittings is the same size as the screw on my pyrometer i need to install so I thought that would be an easy route to go.

 

If you drill a hole in the throttle plate that goes from the intake horn to the pump, in line with the tapped plug, you can put it there. I ran mine in the crossover though. It is tough to get off the first time, those gaskets can stick good. with what youhave loose, its ready to come loose, just may take a little persuasion.

 

I drilled and tapped the cross-over; then, I found the little 1/8" plug in the intake, directly under where the cross-over bolts to the intake.

I am glad I went ahead and mounted the boost outlet in the back side of the cross-over, pointing toward the fire-wall; as, it is a neater place for routing the tube.


While you have the cross-over off, and are drilling it anyway, make yourself a hole (cap-able) where ether/starting-fluid can be sprayed into the cross-over.

What I did to all my trucks is drill a 5/8" hole into the crossover, then installed a farm-tractor-tire fluid-fill valve for tubeless tractor tires.

These are available at any farm tire store, or probably Tractor Supply.

My little ether ports have came in handy a number of times, saving me from the hassle of having to remove a boot to get into the intake stream.

Like already said, just whack it with a rubber hammer and it will knock loose.

The grid-heater section will probably stay with the crossover.

I have yet to be able to get a grid-heater to release from a cross-over; although, they say it will come off.
