Hi, I am installing a Webasto AirTop 3900 heater on my Beneteau 361 and would like to find out how to install the fuel extractor. According to Webasto I can't drill in the diesel plastic tank to install the fuel standpipe, I know I must not install a T in the fuel line to the engine so I am asking for your help please.

Thanks

Hello:

did you ever install the Webasto 3900?

I am thinking of installing one on my 2011 Beneteau 40.

Any suggestions or feedback will be welcomed.

The tank on the 361 should't be plastic. It's aluminum and you can drill into the top if you want but I would just tap into one of the available plugs on the fuel out side of your primary filter housing.

Hi, The tank on my 361 is plastic but I have drilled and tapped. I haven't fille the tank completly yet but I think it should be fien.

Chris,
I have finished the installation last weekend. I had problem with fuse and breaker plus the pump would not start. I finally got it to work and it is great. I will prepare some pictures and post them (this week I hope) plus I will give you some info on how I installed everything.

I'm definitely looking forward to your photos. I have a year 2000 B361 and have been interested in diesel heating for the cold winter weekends on the hook. Will be at the boat show in Annapolis this year looking for deals.

Hi,
I have installed the heater in a space under the propane tank container. You can access this space from the lazarette but the opening is not very large and since I was installing a new Raymarine EV1 autopilot in that area, I decided that is was faster to remove the propane tank container. This is not very difficult, remove 6 screws, unplug the propane drain hose, unplug the solenoid valve wire, unplug the hose to the solenoid valve and remove the hose. You can now lift the container. I installed the heater in this area because it is not used much and I wanted the heater parallel to boat longitudinal axis because I wanted to run the heater even when sailing.
I ran the duct under the shelve in the lazarette, on the high side of the freezer, behind the stove (which I removed to run the duct), in the food locker, behind the navigation center.
I have an outlet in the aft cabin, a large outlet in the chart table seat and one in the front cabin. I will take more pictures and post them. Out 'n About will be hauled out for winter storage on Oct 23 so since I bring almost everything back home I will have more room to take pictures. If you have questions please do not hesitate to let me know. I had a very hard time finding on the net how to install the Websto heating system in a 361. I insulated all the duct with high quality pipe insulation, not the Webasto stuff. I got the insulation from Grainger, 1WZD3 2 5/8 in and 1WZD7 3 5/8 in. I used this type of insulation because the duct runs nesr the freezer and in the food storage area. The duct can get very hot.

I will be at the Annapolis Boat Show so we could meet if you want more details. You can send me an e-mail.
