when installing ventilation hose,is there a grounding wire?similar to the wire on your shop vac system to eliminate static sparks? :roll:

I have never heard, or seen of one, although if one end of the hose connects to a metal vent I would ground the metal vent. I get heavy static electricity when vacuuming up chunks of dried drywall mud with my shop vacuum from these pieces rubbing along the inside of the vacuum's plastic hose as they are sucked up. Since there will only be air travelling through the ventilation hose on the boat, I don't think static electricity will be a concern.

Chug

The fuel tank, fill cap, and vent should be grounded together so there is no static potential between them.

:D Bill-I know that part from install instruction kit;I was mainly asking about the bilge blower and hoses. Guess I should have specified.tho it might be good insurance to put copper wire on the tubing(inside or out?)Wouldn't want gas fumes from bilge to ignite.I think the bilge blower motor is enclosed and would regular dryer venting pipe work?

To the best of my limited knowledge bilge pumps ARE spark protected and rated for use in bilges with the potential for gas fumes to accumulate. I would use the standard plastic bilge fan hose and not introduce metal pipe.

I haven't worried about the sealed fans and pumps. Maybe I should but I haven't.

:D Thanks folks.most boats have inlet as well as exit scoops for bilge and fresh air however my Bo-Jest probably won't be fast enough for those to be effective enough so was thinking on using 2 blowers ;one on a switch and the other hooked up to fuel fume detector.(double trouble?)perhaps wood collection box under the top of rear half of bulwarks.(long skinny thingy)
