Hi Paul  and all

We are trying to make a decision re: fuel system.
I've  attached a PDF with design and questions etc.
Could you please pull it to  pieces, make recommendations?


Thanks

I don't think you want to return the flow from the sump  tank back to
the main tank as the Facet will keep circulating fuel. I think  you want
to seal the sump tank and allow the Facet to make up what is used  by the
engine. Hopefully Perry Mick will chime in as he runs a similar  system.

How large is the sump tank?

Steve,

While facet pumps are very reliable, if your  facet pump fails, you're
immediately down to 8 gallons of fuel, maybe less  once you realize it has
failed.  Just a thought...

duplicate your pumps ----small cost in weight and $.

Hi paul

The sump tank is  8 Gal and is 24' or so above the wing tank.

That is big enough so hot return  should not cause a problem.
