Boost sensor installation
 

1999 F350 PS 7.4 Diesel

I am going to install a boost gauge and was wondering if I could remove the Air intake pre heating (coil gizmo) and put the sensor there?
I can machine up an adapter to thread into the existing hole.
If this works it eliminates the need to drill a hole in the intake.
Thoughts/considerations or wise cracks?
Thanks.
Eric

It's not necessary to do what you are thinking.
The engine has a MAP sensor and all you need to do is tap into that hose with a Tee .
Just make sure the hose to your gauge doesn't come into contact with any hot surfaces when routing it into the cab to the gauge. A 0 to 30 psi gauge should do the job.

Hanky, OK. Sounds like a great solution. Where is the MAP sensor located?

In the engine compartment, on the passenger side , near the firewall, with a hose going from it to the intake piping and a plug with 3 wires going to it. Wire colors should be one Brown with white tracer, one Light Green with Black tracer and one Grey with a Red tracer.

Hanky, Perfect. Got it. Thank you so much!

extra gauges
 

I got a question. Ive been thinking about getting 3 gauges for my ford mustang gt 5.0. I want to know which 3 gauges would be more important to have? Then would it kill my battery more for having the gauges hooked up? Cuz my battery gauge jumps around and makes my headlight & dash flicker from high to low lighting. I have a system hooked up and not sure if that could be the reason. Or just cuz its an old car.

Dave,
If all your connections are tight, usually the flickering of the lights is due to the voltage regulator in the charging system. If the system has a separate voltage regulator you can usually just replace that. If the voltage regulator is incorporated into the alternator you will need to replace the alternator. Everything is probably working OK, but you are seeing the fluctuations in the system by way of the lights and it is just annoying.
