Hello All,

How do you tell if the hand priming part of the fuel lift is working properly?

I have just reconnected all the pipes and fittings to my newly refurbished 200td Bosch injector pump. When I went to prime the system using the fuel lift pump's lever it fully extended down and had little or no resistance for the full length of its return/upward stroke. The lever does not feel as if it is drawing any fuel. Will this lack of draw feeling improve with perseverance or should there be a feeling of suction with the first 10-20 strokes or so?

The part number is STC1190 for a new lift pump. I just want to check to see it normal operating parameters before I assume that Snowy's fuel lift pump's ability to manually prime is kaput.


Kind regards
Lionel

crack the outlet line and pump it.

turn the crank 180 and pump it again.

no fuel flow in both conditions, cactus lift bar.
