Hello Everyone,

I'm beginning my diesel heater installation. I'm installing the heater in the hatch under the salon table. First step was removing the Red Dot which went relatively well. After some leakage, I managed to trim back the coolant hoses and get the space ready for install. I decided not to interrupt the coolant flow circuit for now. It remains a loop.

One of my concerns is where I'm going to draw fuel from. I'm leaning toward installing a bronze "T" in the fuel line after the primary Racor Filters. This may be more of a simple installation rather than tapping into one of the fuel tanks. (If they even have a spare access cap)

Invictus has Cummins 6BT5.9-M's. I won't be running the heater while under way. Is it possible this new "T" might foul up my fuel situation to the engines while running?

Please let me know what you think! I'm anxious to get underway this coming weekend.

Many Thanks, Greg

Adding extra fittings to fuel lines can be restrictive so it is good you are considering this. There used to be and I believe still is, brass high flow or full flow fittings available for those not wanting to restrict fuel flow in a system. I used them on the race cars. Sometimes in certain situations a "y" type is advisable over a "t" but IMO not this case, because you are not using the heater while the engine is drawing fuel.

Have a look around.

Factory install is from a dedicated fitting on the starboard tank on mine. No filtering was installed for the diesel heater draw.

Hello Hans!

Do you know roughly where that dedicated fitting is located on the STBD tank?

Thanks, Greg
