I have a procharger M1 on a 7.4mpi and on the installation sheet it says to T in on any port on the intake manifold.the easiest port i found and can T into is the port thats going into my fuel regulator does anyone know if that will work or know of a better place thanks

Hi

I would like to know the answer to the question as well. Wouldn't it slightly disturb the reading that the fuel pressure regulator gets?

regards,

That is a good location. With that location you will be able to verify that the regulator is seeing when the motor goes in boost. If your gauge is not showing any boost then you know you fuel regulator is not seeing it. If regulator does not see boost it does not increase fuel pressure thus leaning out the motor.

Remember to do a spark plug check after the first short burst to verify the engine is getting enough fuel. If you lean it out you will be rebuilding the motor.

Any vac line or port will work. I agree with Turbojack, that would give you a direct reading on your regulator.

Make sure you check the plugs after a hard run and then turn the key off while still underway. If you bring it down to idle and then shut it down, you'll be reading your idle mixture on the plugs.

sounds like a plan then i will try it and see what happens

Shouldn't the regulator be fed from vacum off the Carb box and the boost guage come from the Intake manifold. They will read differently.

Personally, I think you install the boost pressure guage in the dash

So you install it in the dash and its sends signals to the intake like magic huh LOL

Install the gauge in the dash. The line that goes to it gets installed in a vacuum port in the intake.

Guage in trhe dash - we all agree. Vacuum to the intake. Now where does the fuel pressure regulator line come from?
