Thanks for the response Mtn..
I have 2-pumps..D2 and the Raw power for wvo. I also have a switch on my D2. When starting out, allowing GP's to cycle, my D2 gauge is 70psi (located at fuel bowl), my wvo gauge reads 60+/-psi..(D2 flows thru the wvo lines, back to the puge valve, located in the box). After i fire it up, D2 gauge reads 70PSI, ALL DAY LONG...however, the wvo gauge will read the 90psi-ish..
. Vise-versa, once switch to wvo, the D2 gauge drops to nothing (like it should, since CV's are installed), but my wvo gauge reads 85-90psi-ish.
Also, once i installed the system, it now has the dreaded long cranking, once it fires, i can shut it off, without purging, and truck will fire right back up. Thats whats leading me to think, pressure for start-up isnt there..but once fired, the wvo gauge, spikes high, highert hen the D2 gauge, which that gots me..
I'm gonna switch my the wires to gauges under dash, and see if its my gauge orsomething, along with removing gauge from valley manifold, and installing it back at manifold in box....
3rd pic is of the little manifold in box, where i installed a pressure relief to help with, if reading are correct, pressure in wvo ines.
