I was getting fuel starvation on the track just above 3/4 of a tank which means toward the end of each session. I took the car to
MER in Cresson Tx and they solved my problem. What I didn't know was the drivers side had a fuel level sensor and the opening matched the passenger side. They took a stock fuel pump assembly and installed it on the drivers side and did some wiring and plumbing, installed a relay, ect. I was able to take it on the track and run it down to 1/4 tank without ever having fuel starvation problems. The pump was $350 from Courtesy Nissan and it took MER about 3 hours to do the upgrade.
