Need Help with Piggy Back Fatsac Installation - 2012 SANTE 210

[scubaguy]

Here's a picture of the hose for one side (port or starboard?).. ...a couple of questions:

1. If A attaches to the factory hard tank overflow, why is the hose length from "A" to "B" about 4' long? It appears to me the distance between the hard tank overflow/vent and the rear facing/lower bag port is only about 12 inches.

2. Once the factory vent line is removed from the hard tank overflow, I presume the factory vent line just connects to "C"? I'm curious why "C" has a short length of hose? Couldn't the factory vent line just connect directly to the "T" fitting?

thanks

It looks confusing because that diagram wants you to have a vent for the hard tank AND the fat sac. Reason is when piggybacking you run the risk of collapsing the hard tank due to the fat sac sucking so tight it doesn't allow venting when draining. This is why piggybacking SUCKS!

The hose is probably so long so that the customer can choose to put the fat sac fitting at the very stern rather than where the hard tank fittings are located at the front of the tanks.

What I do is rip those factory hard tanks out and put in a bigger fat sac, that way its SIMPLE, Hose in from the bottom hose out thru the top overflow. done. You also only need to buy the fittings (2 for each bag) and can reuse the factory hose. It works out CHEAPER and way more reliable.

When its time to trade in or sell boat, remove fat sacs and place hard tanks back in. The removal/installation of the hard tanks is an absolute piece of cake on those boats.

thanks for the insight...my hard tank fittings are at the stern which is what i was confused about since that hose is so long... I'm just getting into wake surfing so didn't know what I wanted/needed or i'd have ripped out the hard tanks...and i bought the sacs used at a good price so it was an easy decision vs removing the hard tanks.

Disregard. Misread

Do you have the step by step instructions? If so, then follow them literally and you should be fine. If not, then DM me with an email and I will send you a PDF with the step by step instructions I used on mine with out any issue. That said I did remove about 18” of hose from both sides after I determined the best way to run the lines. Hind sight, l should have pulled the hard tanks and used the 1100 lbs bags as I will likely be doing that during the off season.

Okay - a follow up for those who run into the same issues. The hoses shipped with the kits from wavemakers must be used on many different model boats as the hose lengths are overkill for my application. I didn't bother cutting the hoses as I may sell the kit in the future but I did install the bags with the fill port towards the bow end of the storage bay which helped "eat up" the extra length of hose. Also, the factory hoses can be directly connected to the hose kit "T" connections.

One question I have is why replace the hard tanks plus the 750 kit with 1100's? These bags are 750 and I estimate the hard tanks are about 250 lbs on each side which makes 1000...this install is a breeze... what benefits come with the 1100"s? more storage?

Is there any way to use the factory tank level indicators with the 1100's?

The 1000lb piggy back bag set up costs $600 (inc. hoses/fittings) and the 1100 set up costs about $400 (no fittings).

I think I can answer this question. First off 750s on top of the hard tanks are overkill in a 210. You can barely fill 600s when placed on top of the hard tanks in a 210 so you may get 850# total. Also, many people have found the whole piggyback system to very problematic for several reasons.

No you will not have working ballast gauges if you remove the hard tanks and replace them with 1100s, but this system is very simple and works quite well. It eliminates a lot of the frustrations with piggyback systems and it gives you the most ballast and still leaves some storage space.

thanks for your insight... I don't have a bow bag...which is easiest to install yet provide good benefit?

I piggybacked a Sumo 500# under seat bow bag in my 210, but you won't be able to get 500# in it because there isn't enough room under the bow seats. You will either have to piggyback off the belly tanks or use an over the side of the boat manual pump. An alternative would be putting a ski locker bag in the ski locker, but I'm not sure that will get the weight far enough forward.

One things for sure, if you add extra weight to the rear of the boat you will definitely need to add weight to the bow.

I ordered the Sumo 500 lb Hidden Under Bow Bag as that's what wakemakers recommended and will tie it into the existing bow/locker hard tank...that sound right to you?

thanks.

Yep. That's the correct one.

I had 750’s plumbed into the rear and a bow sac (not sure of mfg) plumbed into belly. I was able to fill all sacs completely but the bow cushions would pop up. Combine that with a wakeshaper and you will have a great surf wave. This was on a 2012 210.
