Hi, fellow rotary enthusisasts. I finally got my fuel tanks and sump
tank installed in my SQ2000.   Today I was surfing the net,
and came upon an interesting firewall fuel filter that has provisions
for routing the unused fuel from the fuel rail/regulator
directly back into the fuel filter, and right back to the engine.
Their advertisement claims "Lite-weight aluminum construction,
provision for 3 bypass holders, eliminates return lines to tank, saves

5 pounds, simplifies plumbing and has an easy to service
washable screen filter" Here is their web site for those interested or

curious.

www.esslingeracing.com/new%20midget/fuel%20injection.htm   I would be
interested in hearing other opinions of this product. I
sent an e-mail to them today inquiring more about it, but as of yet
have not received a reply.  Thanks in advance for your
replies and opinions.  Paul Conner

It presumes having the pump(s) downstream from the filter.  Seems there
is some difference of opinion on that.  My opinion is that a coarse
filter (screen) and gascolator  upstream from the pump is OK, but I
think you'd want about 30 micron filter downstream where you don't risk
vapor lock if  the pressure drop across the filter starts to go up.
Also there is a concern about heating of the fuel.  Waiting in line for
takoff on a hot day and that small volume of fuel going round and round
. . maybe an issue.  I'm concerned about the increase in temp in my 3
gal sump tank.

BTW Guys there is no return flow in the RX8 system. The immersed pump 
has the pressure regulator according to Jim Mederer.
