[QUOTE="TARM, post: 332408, member: 578"] Well first thing I see is your water fuel separator is WAY to small. Its only rated for a MAX flow rate of 40gph/. Your Walbro pumps is sucking about 35-45% more at around 65-70 gph. You should be looking for a water fuel sep that has around 100 gph rating as a minimum. Even with the carter on there its still not gonna help enough as its internally reg to 7-14 psi and once there is does not go over that regardless of flow rate. Your walbro pump is still trying to suck way more and is likely pulling a hard vacuum psi between the filter and pump inlet. I know you found the pickup was clogged but I think this is a issue.
