I have a sumped stock fuel tank with braided steel lines going to an Aeromotive A1000 fuel pump with pre- and post-filters.
When I was getting the truck ready for my move from AK to OH, for some reason, I couldn't get more than 9psi of fuel pressure. Being that I was short on time, I pushed it onto a trailer and towed it down with me.
When I got to Ohio, I turned the fuel pump on, and magically had full fuel pressure, but the truck barely ran due to my roller rockers being out of adjustment. I pulled the valve covers and adjusted all of the roller rockers correctly, and when I went to start it up, got only 9psi again. The truck runs for a second if I use starting fluid, but otherwise it will not start, so I'm pretty sure my gauge is accurate.
I pulled both fuel filters off, to see if something was plugging the system up. The pre-filter is pretty dirty, but not to the point that I think it would block most of the fuel flow. The post-filter is completely clean. The weird thing was that when I pulled the line from the tank off of the pre-filter, it was completely dry. I would think that the line would be full of fuel, as it comes from the lowest point on the tank. Any ideas what could be happening here? Fuel gauge shows about 1/4 tank, and my gauge has always been pretty accurate. When this issue first popped up before I moved, I put a few gallons of gas in the tank and still never saw more than 9psi of fuel pressure.
