I have been looking around to generally improve my p pump on my 97.. I have an Airdog 100 and suffer some hard starts. I was thinking an overflow valve upgrade might be in order. I read something about routine valve adjustment. Does anyone know about this??? Im New to the Ppump.

Valve adjustment is in reference to your intake and exhaust valves. For hard starting issues the overflow is a good place to start also check your shutdown soleniod it could be getting weak.

 

Ok thanks. Well that makes more sense learn somethin every day. I assume Is the over flow valve just a remove and replace item

Heck yeah ... I did my OFV .. Major difference , A few guys in the General Dodge Forum also have the same to say as well ....

Makes them run better with better Fuel pressure ..

Larryb - LarryB's Dodge Diesel, 94-98, Fuel Pressure Adjustment Kit

Good kit and its complete..

 

I assume it would be best to have a pressure gauge first. The adjustable ofv have instructions with them I assume

Oh yeah .. instructions included .. not that its not somewhat self explanitory of course ..
But, with a guage it will be more exact..
( factory set 30-32) .. beleive me its a wake up for most trucks ) ...

 

Ok that looks like one of my next projects.
