Bilge blower hoses

[FuzzDaddy]

Hello all!
I’m still getting some great work and maintenance done. I noticed on my 2002 230 I have 4 vents on the rear deck. 2 on the port and 2 on the STBD. None of them have the tubes on them. The blower motor is mounted directly to the vent on the inner port side. I have a few questions
1) Is it ok for the blower to be mounted directly to the vent or should I have a couple feet of tube and then the blower and than more tube?
2) Also I assume all 4 vents on the rear deck should have tubes routed to match picture below?
3) Even though there are 4 vents only 1 blower is needed?

I don’t want to blow my family up!
Thank you in advance!
Corey

It matters not where the the blower is mounted but you defiantly need to have hose from the intake side of the blower secured to the lowest point in the bilge or engine bay to evacuate any fuel fumes. Having one simply attached to the inside of a vent grate is not doing much for you. I would want one on each side anyway for redundancy.

What he said. Fuel vapor is heavier than air, will settle to low point
