Exciting to start leak testing of the right tank.
Sealing the fuel cap with some tape to prevent false positives:
On the vent side I plumbed a Schrader valve, to prevent a leak in here I used a bit fuel lube.
To prevent overpressure I used a bicycle pump to control the pressure.
Note: I used a pressure of 1 PSI, not more!
(In the build manual is written 1 BAR which is too much and could damage the tank)
On the fuel sender side of the tank I used a cap and an hose adapter:
I built a manometer with an 8 mm transparent hose.
1 PSI ~ 70,3 cm H2O is 35,15 cm on each side.
Fingers crossed that the tank has no leak…
