i have just bought v2 wrx and it has a walbro fuel pump, ive had it out and seems mounted correctly however when car has just under 1/4 of a tank and you go around left hand corner it takes a gulp of air stalls for a sec then ok, its kind of annoying would like to fix it, we do alot of long distance travelling and sometimes were stretching tank fulls between garages, has anyone else had this issue? any help and advice would be appreciated
