would a fuel pump that pumps 240 liters per hour effect a turbo II engine in any negative way?

NO, it will proovide more fuel if you have larger injectors, and have a need for it, lots of people are using the Walbro 255lph pumps, and seem to like them.

You really shouldn't have any ill effects from this. Your mixture may run a little rich if the pressure the pump feeds is too much for the stock FPR to handle it (especially the weak plastic ones on the Series4 cars). Gas mileage may go down a little as well... a fuel pump is a valid upgrade though on cars running more than stock boost.

Well for the moment I will be running stock boost, and fuel mileage isnt so much the issue but thanx much I can go ahead and get it then

yeah, it cant hurt

does anyone know if there is a substancial difference in between the na fuel pump and the TII fuel pump? My lookup comp has no idea
