F4R'd ITB'd '92 cup racer
right, i'm using an upgraded motorsport pump
noticed this at the last trackday, just want to know if it's anything to worry about or try and fix
so when the car is sat idling (it may also do it when driving, but i can't hear it over the engine noise :lol: ) the fuel pump makes a sort of a high pitched whine/whistle sort of noise every now and again, say every 15 to 20 seconds and lasts for 2 seconds or so
i thought it could be sucking up air somehow? but not sure how
any idea's?
