question on Walbro 255lph pump
hey i have a 2005 evo with with turbo back exhaust, intake, 02 hosing, hks bov, upper IC pipe, hks belts, few other small bolt ons and going to be tuned in a week. i want to get a walbro 255lph fuel pump but wanted to know if i need to get anything else with it like a fuel pressure regulator, fuel rail, injectors, ect... is it manditory if i do it or if i just threw it in there and tune it would it be good? also is the lph pump the one i would need or just the 255? reason being was because im low on money and i got a tuning appointment next week. can i just add the other fuel parts later or should i wait on the tuning and just buy everything else?
