Dragged in by AA, code for cam pos sensor. Fitted new one along with t belt kit.
No start. Fuel filter empty, dirty fuel from tank.
Bio/algae type gunk in tank.
Drained and mopped out. New fuel with biocide. Still unable to fill filter. Replaced in tank pump(new bosch), filled filter and ran 20 sec prime via scanner. Started. End of day. Following morning perfect start, 2 mile test drive, check for leaks, park up and cutomer collects. Next day filter empty.

Replaced filter housing as pump seemed unable to open valve inside lid. Still very slow to fill, difficult to prime. When primed starts and runs well for short time.

We are getting about 10 psi from new tank pump, is this sufficient?

Are we missing something obvious?
