Author Topic:   Tempo tank for Montauk

I've been reading the old posts about tempo tanks for a Montauk 170.

I want two tanks, not one.

Trouble is finding this type of tank on the web. I think the right kind is the Ultra PBW 12 gal tank. The Tempo site gives the dimensions as: 20-3/8L x 14-1/4W x 13-3/4H with cap. There are issues like the cap being too tall, but some posts suggest you can replace cap with a Home Depot (or other) replacement, low-profile cap. Also I find other sites selling this tank but giving slightly different dimensions, like 14 inches high - all comfusing!!

Some posts suggest the 13 gal tank, but I can't find that listed at Tempo (at least for the right dimensions). Perhaps the models have been changed. Or, do I recall someone saying the 12 or 13 gal tank is really the same??

So, here are my questions:
1) Are the dimensions I list above for the Ultra PBW 12 right if two such tanks are to fit under the pilot seat of a 170?

2) Are these really portable? I don't see a handle; 12 gal - can that be carried? (I'm guessing you'd really have a bit less than 12 gal, allowing for air at the top.) THIS IS PROBABLY MY MOST IMPORTANT QUESTION!

3) I assume the fittings are not right for the Merc fuel lines (judging by the pictures at Tempo) - where do I find the fittings?

I assume I'd have to reposition the metal loops that hold the straps to the deck. Any input would be appreciated.

These Ultra PBW 13 gallon tanks are $40 each at Bass Pro shops. Quick disconnect fittings are bought separately, about $5 each. Be sure to get late model stock, as they have the new Tempo low profile cap, a nice item. They have no real handles, and at 80# filled are awkward to carry. Some probably do it, however, but not me.

I own a pair of these, and they are a nice product. I prefer the Tempo brand over the Moeller brand.

Bass Pro has the best prices on the Ultra PBW. I think Tempo may have changed the name as they also called it the PBW 13... I think it only holds 12 1/2 gallons from what I remember..

It is the last one is the above list.. Great price at #39.99..

The newer Tempo tanks already have the lower profile cap a LHG mentions but you might be sold one that has been on the shelf awhile with the older, taller cap...

Here are some fuel fittings from Tempo... Most people recommend you purchase the brand of fittings the same as your engine...

Example: If you have a Mercury engine, buy only genuine Mercury fittings from your Mercury dealer or equivilant.... Do not buy the Tempo brand even though they might fit the Mercury.... People have had bad luck with tempo fittings...

I recently installed two Tempo PBW 12/13 gallon tanks, I believe they are the same tank.
1. The pbw 12's will fit under the seat. They will not slide out easily and, through the forum, found out the best way to fuel was from on top, under the seat.

2. They are not truly portable, at least not for me.

3. I have the Tempo fittings and they are working fine, but you can't go wrong with the Mercury part.

You do have to move the metal hold downs. Refer to your wood locating diagram, as the wood below the RPS doesn't extend as far towards the stern as one might think.

If you bring in the Bass Pro Catalog, West Marine will pricematch the 39.99 price plus 8.95 for shipping.

These tanks are not portable. They are advertised as 13 gallon tanks, but the most I can fill them is with 12 gallons. Tempo fittings have worked fine for two seasons now. They don't have the protective sleeves that the OEM tanks had, though.

They do 'fit' under the RPS. It is very tight when the tanks are empty, much better with full tanks. The weight of the fuel fattens and shrinks the tank. I am considering removing 1/8 to 1/4 inch of material from the arch openning to facilitate easier refueling.

The fuel gauges are of no use. I do a 'lift' test to check the fuel level. A flashlight also works.

You will need new straps as well, as the originals will not fit around the new tanks. You have to move the hold downs. Someone suggested that the two outer hold downs can be moved to the aluminum L beam supporting the RPS. This approach takes the pain away from drilling holes into a new boat.

I have recently come to the conclusion that "Theft" Marine's price matching is a scam too. Although it's better than their full sucker price for the inexperienced shopper, it's still a bad deal, and in reality, not price matching at all.

Take this gas tank at $39.95 + shipping + sales tax. A true price match would be the 39.95 + local sales tax. If you walk in to a Bass Pro shop, that's what you pay. If you order the tank by mail, you pay the $39.95 + shipping, and NO sales tax. I've noticed that Bass Pro orders arrive in about 2-3 days max.

West Marine is the perfect outfit for people who can't PLAN
AHEAD. And sometimes, I hate to admit, this includes me.

If I've forgotten to order something, or need something desperately to finish a job NOW, I have to use them, as a last resort. But I hate it!

I have to admit that this information is several years old. I had okay success with the Tempo tank and terrible success with their hose, bulb and fittings. I finally gave up and spent the big bucks for a factory tank, hose, bulb and fitting and never had a problem again. Like I said, this was a few years ago, but not long enough for me to forget, I'll stick with the manufacturers stuff for the few extra $$. Good luck, and smooth sailing.
