Trade: walbro 255 for a 190

When doing research on a stock pump a LONG time ago, some said that it flowed around 110-115 LPH. Furthermore, I also found (on VFAQ) that from the fuel pump outlet to the fuel rail inlet fitting, @ 60psi, it flowed of 1.9 liters per minute, and when the pressure was increased to 75psi, the flow only went up by 0.1 lpm. That's only ~5% more flow for a 25% increase in pressure! So, stock pumps are not that great. You can "band-aid" the system by doing a simple rewire so there's more voltage for the pump, or..just upgrade!
