Hi Tony
My fuel lines start of low to an Andair fuel valve followed by an Andair 375
Gascolator then to two inline filters followed by both fuel pumps all this
is inside
The tunnel, then its uphill to the fuel pressure sender just below the
tunnel top,
Then through the tunnel to the Floscan on top of tunnel behind the
instrument panel,
Then up the inside of the firewall to a position directly inline with the
fuel pressure
Regulator, this gives the shortest run with minimal heat sink, then back to
the firewall going through just slightly to the strb side of the fuel feed
and both covered
In fire sleeve,
Behind the firewall is my second Floscan wired to the Matronics box of
tricks,
I used soft aluminium pipe from the transducer around the firewall and
under the door to terminate into the aluminium vent fuel tank fitting, with
aluminium pipe its easy to make gentle bends to reduce turbulence and
improve fuel flow,
It sounds complicated but it users the shortest runs with the Gascolator at
the lowest point in the system with the majority of fitting protected inside
the tunnel from engine heat or outside cold, The fuel
pumps/Filters/Gascolator are easily serviceable with a drop down door to the
tunnel,
Regards
Ivor
