22 cruiser gas tank re-priming after cleaning

What is the best way to re-prime the fuel in the gas lines and water separator after re-installing the gas tanks after cleaning? I've just moved up to a CD22 from a CD16 and have very little knowledge on how this gets done. The original owners manual does not cover this point either.

Lots of great discussions on C Brats on gas tanks, but I don't see any mention of re-priming.

I would assume that you would fill the water separator bowl with clean fuel, replace on the housing and pump away at the priming bulb until you hear the gas squirt into the carb bowls.

As always, many thanks in advance for the help. :D
 
You've got it. I always fill the water separator filter with fuel, I don't know if its necessary or not but I do it anyway. Just prime the bulb until firm and see if it will start. If the lines are not venting air and stay prime it should be good to go
 
My rancor filters are mounted in a difficult to access place, so I don’t re fill upon changing, but do have oversized priming bulbs. The only problem I’ve had after changing filters was the time one of the priming bulbs failed, then with twins primed it with the other motors fuel line. Now I always carry a spare.

As Jay, we always carry a spare primer bulb, and section of fuel hose. (on occasion some of the older lines have failed due to ethanol content.)

Just this week, I sucked all of the fuel (old) out of my Caracal fuel tank--there is about an 8 foot run from the tank to squeeze bulb. I just left my 'polishing" set up (an automotive fuel pump, filter before, and going into a large racer filter. This then pulled a prime thru that 8' line, (The fuel filter was profiled. Hooked up the bulb to the line to the filter, and the engine fired immediately. There was a cup or so of good fuel in the polishing system--and this was placed back into the clean tank,
 
I turn the separate electric fuel pump to ON. It was installed by or maybe left by the old owner. comes in handy when I need it. the fuel still pulls thru it when it is off.
 
Oh and as I have it before the racon fuel filters with a drain, I can use it to fill other tank. I place a hose on the drain in the filter and then fill small out boards or small tanks for the dinghy. I have even used it to transfer fuel to other boats that are out. Nice tool to have and cost very little.
 
I always fill The Racor filter with fuel after replacing it.
Next I remove fuel line from motor at the quick connect.
I then use small plastic probe to push the locking ball back.
Place a rag the the fuel connector.
Pump the fuel line ball and all air will purge out quickly.
Connect fuel connector and enjoy the day!!

On my last boat(inboard) I installed an inline electric pump solely for priming. If I ran one tank dry it took a LOT of cranking for the mechanical pump to get primed. Excessive cranking is not good for an inboard. It also worked good when changing filters. Not to be used to fix a worn mechanical pump unless it is bypassed. You can end up pumping fuel into oil via the failed diaphragm on the mechanical pump.
