ive just ordered the above off e bay (only 20 quid) thought id give it a try before i shell out 200+ for an electric one! everyone was saying these are just as good any way. question is .... where do i put it? do i blank off the amal valve and put it between the compressor and the actuator? or do i still use the amal valve and put it between that and the actuator, or none of the above? is it right in saying i can ditch the actuator spring now that i got with my eds kit? all help appreciated people!!!
