Hey does anyone know what the little t style valve is below the vp44 pump? 01 24 valve auto...it’s just a little brass t style

 

 

Toss up a picture.

Well have to in the morning, sorry..

 

Needle valve? Like a NAPA WH6820...

Bad idea...

 

First off that is not a good place to measure fuel pressure. Second off electric sensors needs a bit of travel room from the snubber. The needle valve is a poor snubber for electric senders. You need a sinstered metal snubber then at least 5 feet of tubing to the sensor.

I didn't know there was 3rd outlet there for anything.  Beside it being a bad place for the sensor, will that port read supply pressure?

There isn't really. There is a body plug right there someone used as a fuel pressure tap. 

So that’s for a fuel pressure sensor....sorry I’ve had 12 valves my whole life, this is my first 24 and vp pump so I’m pretty dumb about it....so what does it control if I open it or close it?  Just the fuel pressure reading?....doesn’t have a gauge in the cab for that...

 

Needs to be removed. Then a plug placed back in the hole. But I doubt you'll fine a straight thread plug that goes back in that pump.
