Hi Guys,
I'd like to know the right way to set up twin saddle tanks and a hopper tank (3rd) tank in my ducted fan. Do I "T" the twin tanks into the hopper, or run them one after the other in series??????
Thanks
Ernie

Ernie,

I have always plumbed the saddle tanks in parallel to feed the hopper tank, and it has never failed for me.

Have both the mains feeding feeding the center and use a T with safety wire it on.

Best Of Luck

Ok, just to make sure I'm on the same page as you guys, your running both main tank feeds "T'd" into the hopper's vent, the hopper pickup to the carb. Both main tank vents "T" off the pipe pressure.
Is this the setup your running?
Thanks
Ernie

Yeah, use this picture as a reference.. discard the regulator in the diagram, use it as your hopper tank..and the check valve as pipe pressure tap.

If you are going to use the parallel system, make sure the lines coming from each tank to the T's are the same length.

Ernie,
Here's the BVM instructions. As bcovish said, keep the fuel and pressure lines to the saddle tanks the same length. After I plumb mine I usually fill and drain them several times using my electric fuel pump to make sure the saddles drain at the same rate. If they don't, shorten the fuel line to the tank that takes longest to drain a little bit at a time untill they drain at the same rate.

I have found the Y- fittings seem to flow better than the T-fittings .

Thank you Guys!!!!
