Default High Pressure Fuel Pump

Hi All,

Firstly glad I found you. Secondly I'm so new that i'm still learning to spell Sprinteer.

At the moment i'm leaking fuel from high pressure fuel pump.
Mercedes Sprinter - 2003 - 413CDI



I went to wrecker and got a second hand one for $400 installed it pump has exact same fault.

Returned to part to wrecker.

Went to Diesel repair shop up the road with my pump and got quoted over $1500 to repair although he brushed me off without a second glance at the pump.

Went to another shop who quoted $800 and another who said you can't even fix these.

Wrecker I bought the second hand one from believes its as easy as finding some parts and a newbie could repair them.

Can anyone give me any advice on this? I've got so many people saying so many different things and none of the match up.

Ha ha. Sounds like the exact same scenario that caused the previous owner of my small sprinter to sell it...
Remember, these are diesels. They need FULL pressure at the injectors to run. They are not like a gasoline powered car that just needs a whiff of gas to get them to start.
You have to bleed the fuel lines all the way to the injectors and make sure you get ALL the air out of the system for them to finally start after replacing the fuel pump.
For more help, use the "search" function in the bar up at the top of the screen.
Welcome to the forum!

Hi Type2Teach, Thanks for your reply. Surprisingly the engine will start at the moment although there is a steady stream of diesel flowing out of that area.
I'm sure if I left it on it would eventually stop also.

SGau,
Do not think the diesel will help your belt life. A fiend in the mechanical repair business uses MTQ below, thats who I purchased mine off/Thru friend, when I had low pressure. They ship all around Oz

http://www.mtqes.com.au/

I think the Doc on the US site can ship out parts for a refurbish, but could take some time to arrive. MTQ from memory also need your old unit back which also reduces the cost.

When you put the HPFP back, make sure the plastic tubes underneath the pump are not close to the belt, sometimes the clips can break when you are removing the pump.

Peter

@Eric unfortunately in Sydney any hints and tips though would be great? If i'm understanding correctly the washers/ O rings on these things fail and we get leaky fuel everywhere. I haven't been able to find anyone who'll tell me what the parts inside are or where I can find them. Surely it should be as easy as popping the bolts and replacing and closing?

You have the pump of the motor so can you describe the leak, is it around one of the heads or is it from the shaft or the end cover? Eric.

@Eric
If you click the pic i have linked in the original post I think it kind of shows a whiteness coming from the top part of the pump. Thats all the leak there is nothing else coming from anywhere else.
