Raw water pump and tubing

[demarko210]

I purchased a new seaflow 33 water pump for my raw water. The barb connection is 3/4 inch and the tubing i purchase is 3/4 inch ID. WHen i attach the barb to the tubing it slide in and out without adding the clamps to it. My question is, is the correct size tubing for the barb or am I going nuts? Also this pump says us a 18amp fuse should I go 15 or 20?

Why would you not use the recomended 18a fuse?

If its 3/4 nipple and 3/4 hose just clamp it and take a nap. Keep the 18 Amp fuse.

There is no fuse attached to the device unless its inside the motor. The instructions stated to use a 18 amp fuse, I was asking if I should use a 20 or 15 since i can not find a 18 amp blade fuse.

Good point. IF I'm looking at the right pump it draws 8 amp max, I'd go with a 15amp.

Pump Model: SFDP1-030-045-33
Pump Voltage: 12V DC
Pump Flow: 3.0 GPM
Pump Shut-Off Pressure: 45 PSI
Pump Max Amperage: 8.0 A
