I called Walbro and left a message. They called back and are going to send out parts to fix the issue. I told them what I did and that I did not expect warranty to apply with the bad tanks/fuel/etc. They indicated they were working on kits, but, are taking care of me no charge. At least I get a break on 6.5 parts for a change. Maybe I am the only one to FUBAR a Walbro pump and as new is the FRB-15 is...
Sigh... this gives me serious concerns about the IP's condition.
