Stainless Fuel Water Seperator & Drainable Bowl

[T-Topless]

Several people have asked, so here is the best deal I could put together:

Sierra 7776: Sierra Stainless Steel Filter Head, (4) 3/8" NPT-F (use 2, plug 2), (Mercury/Yamaha 11/16"-16 filter thread), includes (2) brass plugs

Sierra 7928 (Racor B32013 equiv) kit which includes:

• 7919 : Spin-On Fuel Water Separator Filter: 10micron, 90gph, Tall (Racor S3213 equiv) (Mercury/Yamaha 11/16"-16 thread), 3.8"D x 7.2"H size
  &
  
• 7922: Aquavue™ Clear Bowl with Drain-Cock (O/B above deck ONLY)
  

To install, you will also need (not provided):

• (2) 3/8NPT-M x 1/4" or 3/8" hose barbs
  
• (2) stainless (3/8-16 x 1-1/2" or 2") machine screws with washers and nuts to thru-bolt, or stainless screws into transom
  
• may need 1/4" or 3/8" ID ethanol approved, marine rated low permeation fuel line (complies with USCG Type A1-15 requirements for pleasure boats, SAE J1527 Type B1-15, ISO 7840 Type A1, NMMA/CE accepted, EPA/CARB certified)

This setup is ONLY approved for above deck mounting (below decks requires a metal bowl).

It is also pretty tall , 7.2" filter + 3-4" for bowl + 1-2" for bracket =~ 12" above your deck.

$99 + $12.50 shipping.

If interested, PM or email me ... this in not on our web-site price list (yet).

If I can ask a stupid question? Why is a metal bowl required below deck? Do the clear bowls crack or leak, because of heat build up below deck or something? Is there a metal bowl with a drain-cock, thingy on it? The reason I ask, is that all my fuel lines run below deck!

[intubaited]

easy-I have looked and can't find that anywhere but I've heard it many times. What I did find looks like the drain on the bowl isn't allowed above or below deck. No offense to anyone:

§ 183.556 Plugs and fittings.

(a) A fuel system must not have a fitting for draining fuel.

Dunno. Maybe someone else has more insight into the regs...I know a bunch of folks who have installed them.

Was talking to a guy today at the marina and he said to be careful using the clear one because the ethanol has been known to actually eat them up. I'm not sure if it's true or not, however, he has no reason to lie to me.

I believe that was a problem when ethanol was first introduced but I think that problem has been corrected for some time, as has the issues with fuel lines and other components.

I found this on the Racor site! See-Thru bowls can only be mounted below deck with Outboard Applications. If See-thru bowl is used with an I/O or inboard, the filter must be mounted above deck for USCG approval. Metal bowls can be used for inboard or outboard applications above or below decks.

Racor fuel separators can handle up to 120 gallons per hour. Choose from models 120, 320, and 660 and refer to chart below to determine appropriate application for your inboard or outboard motor
Racor filter/separators will not separate oil from gasoline in blended fuel mixtures
Includes: Fuel Filter/Water Separator with mounting head, Spin-On Element and See-thru Blue, or metal Bowl

That's interesting. I looked for it in the USCG site and wasn't able to find it when I was installing mine. Good to know! Thanks easy.

Safety issue - no plastic or drains below decks on I/B or I/O. Seems you could do it on an O/B, but I wouldn't risk it.

The plastic bowls produced today are fine with alcohol. Older bowls may have had problems, but the Sierra stuff is ALL rated for ethanol.

Side-Bar:
Funny - the old fiberglass Whaler Montauk tanks all had to be thrown away because the ethanol would eat them and send globs of stuff down the fuel lines and plug everything. E-10 is E-vil ... E-15 will be worse. Had 2 local clients call this week trying to figure out what to do with full tanks of phase-separated fuel that won't burn sputters and backfires). Local boat dealers are backed up 2-3 weeks and charge $5/gallon to suck it out and get rid of it. One was 72 gallons, the other was 100 gallons. Told them they're welcome to use my fuel-polisher ... old gas will still be weak, but it will burn if you get the water and phase-separated ethanol/gas out of it - and you can just cruise slow for a couple of outings.

So what your saying is you can use gas that has ethanol in it as long as.you have a fuel water separator in line. Correct?

[T-Topless]

Yes - to a point ... At some point the separator will fill with water and you will get no fuel (will need to empty the water). You don't want this to happen while you're in q tough inlet, or a following sea.

FYI - The separators WITH a drain are allowed ABOVE DECKS by the USCG.

There is also a layer of phase separated ethanol that doesn't burn well - and may actually make it through the 10 and 20 micron filters. That's why I polish older fuel with a 2-mcron fuel-polishing system I built (but seldom use now because I avoid Ethanol tainted fuel).
