Expert 2.0 HDI 37,000 miles. I stupidly ran out of diesel. Topped up and have done 600miles since. On checking found metallic bits in fuel filter housing, not ferrous as could not be picked up by magnetic screw driver. Engine starts and seems to run ok. Have I wrecked the high pressure fuel pump cranking the engine with no diesel   The expert is fitted with an electric primer fuel pump. UPDATE 21/02 16:15 Thanks for the quick and informative reply "oldplug" I have just cleaned out the filter housing again and replaced the fuel filter. I plan to replace the electric fuel pump and clean out tank and fuel system asap. I see there is a fuel return system, Should the fuel filter stop the metalic bits getting to the high pressure fuel pump and the injectors ? |

It will be the electric pump in trouble,a known problem.Peugeot were changing the whole fuel system on 307`s £1000`s!!! The metallic bits are not doing the system much good so every thing must be cleaned out including the tank.

Spot on Oldpug. The pumps are cooled by the fuel in the tank, so those in the habit of running low regularly, or running round perpetually on 1/4 tank, run the higher risk of the pump failing prematurely.
With any luck you've caught it early, but worse case scenario can wreck the whole fuel system, injectors, high pressure pump, pipes, the lot, which can cost a few pence to sort.

I have just cleaned out the filter housing again and replaced the fuel filter.
If I regularly monitor and clean out any bits in the housing and change the filter might I get away with not flushing out the tank and pipes as the fuel being pumped through is doing this for me??? Will the electric pump definetly need replacing???

If there is more than the slightest sign of swarf I'd replace the lift pump. They tend to go around the 80-120k mile mark, if that's any guide in your case.
The pumps aren't hugely expensive, about the £100 mark, but I have to confess to not knowing how easy a job it is on the vans (on the cars you lift the rear seat and access is straightforward).

Many thanks again for the quick response "Piston Broke" great technical forum.
I know your right the pump should be changed although I have only done 37K, 2 months out of warranty....
I'm probably just looking for a little reassurance as I need to use the van meanwhile. Do you think I will be ok, as in not cause further damage using the van for about 2 weeks/700miles before the work is completed, I have already done 1,000 miles since dry tank.
I will have to remove the tank as there is no overhead access.

If it were mine I'd get it done soonest. I can't say how likely it is, but the risk is that if it lets go big time it'll contaminate and damge the entire fuel system, which could cost enough to write the vehicle off.

You will have to remove the tank to get the pump out on vans.Its not a bad job providing its very low on fuel.Then when its out give it a shake and get rid of the fuel left in,or have it flushed out.When you refit the tank look after the breather pipes,they can get trapped.

Update after 12 months and 12,000 miles later... Useful Information.......
I did not change any parts and all is ok. It has been suggested that the grey material in the fuel filter housing may have been there from new as this was the first fuel filter repalcement and the particles were probably paint residue from the fuel tank baffle plates.
Hope this helps for future diagnosis.

Do the HDI engines not have fuel coolers? My two smart cdi cabriolets do. The 2005 car has 183,000+ km on it so far. I know that boiling fuel can be an issue with smart (they interdict elevations above 2600 m) for that reason, even with a fuel cooler! It's easy to get above 2600 m in North America, not so much in Europe (with a car)!
