Hand Priming Pump

[Tomcat]

Hi, anybody know how long you have to pump the b9 diesel priming pump by hand until it fills with fuel? Some say a few pumps, one guy said 10 minutes. Anyone have practical experience of hand pumping the primer. I can't get my Berlingo running, I have a buzzing sound coming from driver side fuel system area and I thought I might try to hand pump up some fuel and see what happens, but after a few minutes and a sore hand the pump still isn't filling.

They can be very tricky to bleed, some pump up in about 20 seconds , but I have had many that simply won’t at all.
Big issue is that the pump device often sticks down, so you can’t use it anyway..
Luckily we have a suction oil drainer, so simply pull it through the filter using that , works in seconds every time.

I am managing to get some fuel into the pump bulb by hand. The rubber pipes are too hard and brittle and I can't get them off to attach a pump. Does the bulb actually have to be so full of fuel that is full or just so that it can be heard and felt in the bulb? I actually had the car running for a minute a few days ago but now all I get is the starter cranking and if it was a petrol I would say the timing was out. I wondered if it was dirty fuel as I have disturbed the filter during the process of changing the clutch so I drained the filter a few times, about half a cup full each time. The van was last registered 4 years ago so I guess its been sitting for quite a while although it was driven maybe 20k before the thrust bearing gave out and I bought it and towed it home. It was owned by Toll courier company so was serviced and has only done 150,000k. Cheers

The pump doesn’t tend to go hard on these models, you can just feel the fuel in it usually.
Sounds like the pump/lid assembly is leaking, may well be worth getting a new one.
I have changed a couple and they normally bleed straight away when brand new.

Thanks for the reply, I am not sure which part you are referring to that you think needs replacing, is it the fuel pump itself or the primer? Cheers

The primer, it’s in the fuel filter lid, won’t be the fuel pump itself, I doubt.
