On our boat we had 2 racors in parrallel each had a 1/4 turn valve on the inlet and the outlet but only one was in line at anytime, the reason being is underway if your engines started starving you could open up the inlet and outlet on the one that was standby and then close the one that was in operation and change the fuel filter while never stopping and I have had to do this more than once, its pretty easy to change the filter on the Newell so thats not cost effective to do that but its a quick solution if its a plugged filter. Gauges on the inlet and outlet to show differential pressure would work if you could get your wife back there to watch them while the engine is loading.

Thats a good thread Steve! I carry jumpers just for such emergencies.
