I thought most pumps blow better than they suck. Isn't that hard on it?

The walbro pump I put in my system came with a warning that if the internal
filters on the pump became clogged, the pump would become useless and would
have to be replaced. The only logical way to set up the pump is to put it
after the filter.It seems to work very well in this position. fred

Hello Fred,
The Walbro pump has an easily replaceable (and cleanable) screen filter. It
takes about ten minutes to do.
To quickly and easily clean a Walbro 68xx pump:
Take off the metal band mount band. (1 Nut)
Pop off the brass end caps with a flat blade screw driver
The plastic housing falls open like a clam shell
Undo the three screws holding the base triangular plate on.
Pry open the base plate with a flat blade screw driver
The screen filter will fall out into your hand.
Clean out the base chamber. The screen can be gently cleaned or replaced for
about $2.50
(Yes Walbro sells a replacement screen for this "unserviceable" filter.)
Carefully reassemble. Make sure no grit is caught in the o-ring.
Check for leaks.
Time: about ten minutes.
Money saved: $150
Let me know if you need help. I'll e-mail you pictures and directions on how
to do it.
Thank you,
Charles Bell

Unless there is some overwhelming reason, any pump should always be
protracted with a filter/strainer on its suction side. I have measured the
output of the Walbro with a GCF JR on both the suction and discharge with
water. The flow rate is almost the same.
The Walbro warranty is voided if a filter is not installed on the suction
side of the pump.
