Working on my 98 civic again today. I wired up a fuel pressure sensor to the ems yesterday, the filter strainer sock was collapsing into the pump, fixed that. Still losing fuel pressure over 8500rpm, still going lean. Walbro 255 with 55# injectors, I'm going to try hotwiring to the tank again, but also double up the wires in the tank to the pump.
