Well got check valve back in booster pump. Plugged over pressure valve at filter head and put a thin washer in the overflow valve spring on the side of the hydraulic head. Pressure was 40 psi idle and I had to stop at 1500 rpm because pressure hit 75 psi. Took shim out, tested with no shim and back to the 0 psi drop once it hit about 50 psi. Tried a thinner shim and was able to hit 75 psi at 2500 rpm holding steady with ZERO surging….but as soon as it returns to idle pressure drops to zero slowly. Idled for 10 minutes to see if pressure would come back up and it tried to hit 10 psi but would drop to zero again. Only shutdown and restart would “reset” whatever is sticking.
So kinda closer to figuring this out but not really. My next hunches would be booster pump cavitation maybe, possibly the new brass sleeves in the synflex line being too small causing restrictions because they are much smaller in size than the OEM brass sleeves.
Im burned out on the truck, I don’t care to work on it or look at it for the first time since I bought it. This truck was a total basket case that I’ve tried to do my best on but she has the better of me right now. Lots of lost sleep, time with family and money. So I’m gonna take a break for awhile. If anyone has a booster pump for sale, I’d appreciate it. Thanks again to those who have helped with parts and advice.
