it shouldn't be dropping that low

 

I love my Raptor Need one fer Goldie

 

yah, you can pull a stocker way down. Course, his overflow valve may be shot too. My OFV was new and I could still pull it down to about 14 psi with my little stocker 175hp injectors.

Them stockers are a joke. Pure and simple. It took me a long time to actually become convinced of that, but now I've learned my lesson.

 

I had brand new fuel lines, filter, cummins lift pump and adjustable OFV set at 32psi. At 2000rpm I'd have 32psi. At WOT w/181s it would drop to 10-12psi. After the switch to 024s, it would drop to 7psi.
