'95 1.9d Leaking Bosch fuel pump - Louie
Just been reading Leo the Lion's thread about his diesel pump and so thought I'd get in with a question of my own.

My Bosch diesel pump on my 95 peugeot 405 is leaking from where two parts of the casing are joined. It's the join nearest the out lines to the injectors where there appears to be a slight recess on both sides of the join. It started as very small but now it's weeing out.

I'm dreaming it's a gasket that's gone and I'll be able to pop down the local corner shop and get one. In this dream I'm also able to refit the gasket without having to remove the pump and faff with the timing belt.....

Whaddya reckon.... Ta Louie

I've owned two Peugeot 405 diesels, one had a Lucas pump, and the other a Bosch. Both pumps started leaking at about the 200k miles mark.

Although I did most jobs on the cars myself, including head gasket and clutch changes, I used a local diesel specalist to sort the pumps out. Basically, I wouldn't attempt to open up an injection pump without the experience / tools.

Hope you get it sorted, they are great cars. I only got rid of the last one because someone drove so hard into the back of it that it needed a fork lift truck to open the boot up to retrieve my possessions!

dear louie ,you could try tightening the 4 small allen screws at the end of the pump, it may work , at least you have nothing to lose.
if this does not work i,m afraid it may have to be a second hand pump from a scrap yard
i would not try to fix it yourself , all pre-direct injection pumps are very complex and certainly a job for professionals.It probably is a gasget , but not being a pump specialist , where would you get one ?
you will have to mess about with the cambelt and it would be wise to replace it once it has been disturbed.
i hope you are successful with "nipping up the bolts"

Ta Richie tried tightening the bolts first off to no avail.

Yeah I'd kinda always feared the worst so it's off to the scrappy on Monday for a 2nd hand one then replace the seal at my leisure for a hoot. Found a step by step guide with pictures to reassembling a bosch elsewhere ont web. Just thought there might be an easier way.

How I'm gonna get to the scrappy is another question entirely. Thinking of using a liberal amount of brake cleaner then chemical metal the join and see how that runs in the morning..... or maybe just gaffer tape hmmmm hahahahaha.
