Hi James,

Was really just thinking out loud. The question is, do 044 pumps loose flow because of mechanical wear of because of something else? In either case monitoring of current would tell you a lot about the pumps current state, more so actually than measuring the voltage at the pump. This is all probably pointless for the OP but interesting all the same.

As an example, I monitor ignition coil current, that tells me absolutely every thing I need to know about the coil. Short, open, coil saturation point for ideal dwell times etc. Its really very useful.

All the best, and I'm sure either way the loom will be of great quality.

Rob,
