Big Orange Filter - How long of a vent hose do I need for FV310?

Jstew

2001 FV310.   Anyone know off hand how long of a vent hose I need to order?  I'm going to mount the original Big Orange to the top of the tank and I know I need to create a loop.  I found the proper 5/8 ID hose at west marine's site but I just need to know length. My boat is 2.5 hrs away and I ran out of time today before I could measure.

@Jstew there should be some posts on this forum on pictures of the Big Os installed. I think I posted a few over the years. Try our search thread!

@jstew, you don't need that long of a hose because you can use the existing hose, leaving it on the hull outlet and then all you need is an additional hose going from the tank to the big orange.  So, 3 feet of hose should be fine for that.  Make sense?

Perfect.  Thanks, Dream inn

It doesn't need to be that long.  It does depend on where you put the big orange filter. The existing vent line should be long enough as you will just connect that to the big orange filter. You'll then add the new one between the big orange filter and your waste tank.  Get 6 to 8 ft and I'm sure you'll have a lot of room to play with. It's a few dollars more to get extra length, so not worth getting an exact measurement, just get more than enough.
