Hot Gas Puff-back and
Heavy Smoke Hazard
Failure to bleed the pump properly could result in
unstable combustion, hot gas puff-back and heavy
smoke.
Do not allow oil to intermittently spray into a hot
combustion chamber while bleeding.
Install a gauge in the nozzle discharge port tubing or
fully open the pump bleed valve to prevent oil spray
from accumulating in the combustion chamber when
venting air from the fuel pump.
Ensure that all bubbles and froth are purged from
the oil supply system before tightening the pump air
bleed valve.
