Priming bulb - where to put it?

[Latestarter1]

All the common rail diesels I have messed with have electric pumps in the tank which pumps the fuel through the system, no need to bleed anything, just switch the ignition on and wait a few secs before cranking. The older Pugs had squeezy bulbs to assist the lift pump. No lift pumps as we know them, on common rail diesels!

Many versions of the Bosch CP3 common rail pump have a quill shaft driving a lift pump on the back of the pump. On vans the battery capcity is limited and battery almost flat before system primes. Certain workshop priming practices have resulted in a gob of air getting into the injector and blowing the tip clean off, probably churning the motor over before electric priming pump had properly primed the system. Never forget a common rail injector is subject to pressures similar to those in the breech of a .22 rifle. Only two weeks ago I saw workshop numpties engaged in the dangerous practice of all pre-filling diesel filters when servicing a 7.5 tonne truck. It only takes a speck of contaminant going through the gear pump to snap the quill shaft.

I would say that the "pattern" bulb would have hardened with what ever you put thru it.

I'm not sure what you mean. The bulb was fitted to the fuel system of my boat, which uses diesel. Raw hydrogen or carbon was not involved.

Identical bulbs fitted to two other boats at the same time also deteriorated in a similar manner.
