cheers dave, lewis phill and bryan. i did dissconnect it after fuel starve. its still running the standard pump lewis. i did have the 255 in for a while a few months back but it didnt like it. so took it back out till i got a remap. did not think fpr would need mapped in but looks like i will have to wait till i got a mappable ecu then install the yello 440s, fpr and walbro then take a canny run in to get it mapped. when fpr was connected it was sitting at about 48psi on the standard pump. again cheers folks for the info.
