May I ask one more related question? I'd like to add a second fuel shutoff to the chain. Already one at the tank, so I thought one near the carb?
If the secondary shutoff became closed would the backpressure faced by the pump be harmful?

Tank -->FS1 --> H20/filter -->F1 -->Pump-->F2 -->FS2 -->FPG --> Carb

FS1 = fuel shutoff primary
F1 = Filter1 (coarse)
F2 = Filter 2 (polishing)
FS2 = Fuel shutoff secondary (to be added on bulkhead)
FPG = Fuel pressure gauge (to be added on bulkhead)

Also, how about some sort of manual drain petcock to mostly drain fuel from the lines before disconnecting hoses? Or would that be another point of failure?
Thanks
DonC
