thanks for the info guys. i've done alot of looking around the past couple of days on this bonding issue. seems to be alot of differing thoughts out there... i've linked the filler caps to the tank necks and those run to a common ground. i may change this as i continue to research
i went ahead with the shoot thru transducer and temp sensor. i'll find out tomorrow how it works as i'm hoping for a shakedown run...here's hoping my calculations were correct and the floor stays dry
