My montauk came with the Moeller white Whaler Topside Fuel Tank and the fuel gauge gets fogged up. Does anyone have a fix? Also is this a 22 or a 24 gallon tank? (I googled it and found both results)
Thanks
Ruf

Only one size listed on the Moeller site in white. 22 gallon.

The Moeller white tank for Boston Whalers (part # 031626) is 24 gallons. Yes, the Moeller web site lists it as 22 gallons in the link above. I believe this a typo. It happens.

There is only one White tank like this.

As far as the fuel gauge in the gas cap goes, contact Moeller customer service. They have been very good about responding and replacing some defective caps.

Thats very interesting, Tom. I went to Moeller's site and they list the 22 gal tank and give the measurements. It is the tank I have on my Montauk 17. I then googled "Moeller 24 Gal" and found a site which lists a 22 Gal and a 24 Gal both with the same dimensions. The thing is, I think my tank says 22 Gal. Now my boat is about a hundred miles away so I can't check, but you'd think that a company like Moeller would get its act together.

---

Who knows? Maybe they reduced the rated capacity because the caps leaked?

I have a friend with a Katama. We bought one of these tanks for it a couple years ago. I put 24 gallons into it.

---

You're a good friend can you put 22 gallons in mine?

---

Tom - Thank you. Moeller customer service was excellent and are replacing the cap

I finally received a reply from Moeller regarding the Boston Whaler tank. I had asked why my 22 gal tank's dimensions were the same as those advertised for the 24 gal tank. Here is the reply I received:
"Henry,

Good Afternoon. I apologize for the delayed reply. Often tanks are shown either in actual gallon capacity (the full volume) or it may be listed as the recommended fill level (this will be less). If I can be of further assistance, don't hesitate to contact me.

It would be interesting to know exactly what is stamped on the tank for the capacity.

22 gal US
24 gal US
etc.

Let us know what you find listed on your tank.

Even though the 24 gallon tank and the 22 gallon tank are the same overall dimensions, they are shaped differently.
This is probably why they list the white one as 22 gallons.

Moeller does not list the white one on their site as 24 gallons.
Does anyone have a link where Moeller does list the white one as 24 gallons? Not another site, only Moeller.

My tank is marked as 22 gallons. I take it from their response that even though the tank will hold 24 gallons they state the capacity as 22 to prevent spills. I once filled my tank after a day on the water and the next day the gas had expanded and was leaking from the cap. I now leave about an inch of air and because the deck is slanted to the rear, if the fill were on the forward side of the tank I could probably fill it more.

---

The red tank used to be listed as 26 gallons. Did they reduce that by 2 gallons too?

I believe Moeller has down rated the capacity of all of their on-deck tanks larger than 6 gallons. I have a pair of the BW 12's, which began life at 13 gallons rating, and are now 12's. Same for the long, low tanks that fit under Whaler thwart seats. All have been down-rated. I have a pair of the 20 gallon tanks under the stern quarters of my Ribside, and now that tank is being shown as only 18 gallons.

I believe it was done because of the new anti-vapor/anti-spill EPA regulations on tanks. There is now more room for expansion also.

And actually, they are more realistic capacities. On my 13's, I can only reasonably get about 12-1/2 gallons into them at most.
If I forced 13 into them, I would spill gas doing ti, and they would always build up internal pressure and squirt gas when plugging in a fitting, or force fuel out the cap vent. Same for my 20's. From day one, I could only get 19 gallons into them at most. I think their earlier capacities were a stretch, and were for unrealistic brim full situations on an absolutely level platform.

Yes, that makes a lot of sense Larry. I bet you're right.

Here's another mix in the pile.
Moeller shows another 22 gallon tank in White but on their website they show it as red.
It has the same overall size as the white 22 gallon and the 24 gallon but has a fitting on top for a fuel gauge.
This 22 gallon has the same shape as the 24 gallon except with a fuel gauge built in.
Not sure what BR stands for in the part number but it appears that every tank that has the BR also has the built-in Fuel Gauge.

031626 22 gallon White
031626BR 22 gallon Red but they say is White (built-in fuel gauge)
031526 24 gallon Red

EDIT:
I just noticed something else.
Both 22 gallon tanks are 29.25"Lx20.50"Wx12.25"H
and the 24 gallon tank is 29.25"Lx19.00"Wx12.25"H

How can the 24 gallon tank be 1 1/2 inches less in width yet carry 2 gallons more?
I think Moeller needs to fix the sizes or gallons of their tanks on their website.
Something is not right. Very poor information.

I just bought a Moeller white tank on craigslist. It must have been one of the earlier manufacturings of this Whaler-specific white tank because it shows 24 gallon capacity on the tank itself. According to Moeller's response above, this must be the "actual gallon capacity (the full volume)", as the tank is the exact same as the ones I compared it to at West Marine which show 22 gallons as the capacity on them, now that Moeller is apparently listing these tanks at "recommended fill level"

This change across their full tank line, combined with the fact that some online retailers use old info and/or incorrect pics most likely the cause of the confusion.

The white tank made for Whaler's has not changed in any way though...I compared mine stamped with "24" side by side to the new ones sold at West Marine stamped with "22" and they are identical.

One difference on the EPA compliant red tank is that the inside of the tank is coated to reduce vapors. I doubt 2 gallons different, but it reduces the volume somewhat.
