Rowland=0Aisn't my vent system effectively the same as the factory setup? T
here will still be a +ve pressure on the tank.=0AGraham=0A=0A=0A=0A=0A_____

e=0A =0A=0AI was originally going to use Tony K's conditioning and display
circuit. Tim Houlihan had planned to do the same, but we couldn't get the v
arious bits to behave sensibly (RS-232 & Windows issues, as I remember). Ti
m switched allegiance to the MGL display device and got another friend to d
esign a conditioning amplifier to interface the the RS sensor to it.=0A=0AI
've now adopted the same approach and attached are some PDFs and a JPEG tha
t show what I did (op-amp circuit, stripboard layout, MGL wiring, sensor &
amplifier in box). As it's not installed yet, I can't offer proof of functi
on but I know Tim's works fine. The only potential problem is ram air press
ure on the forward-facing tank vents causing change of reading with airspee
d. I intend to avoid that by using Graham Singleton's vent arrangement.=0A
