Thanks for the tip! I'll have a look too..

It seems to me that it might be an easier job to replace the entire filter unit after a few years of service. They just don't make 'em like they used to!

Which means you will probably throw away a well made solidly built old filter body and replace it with a newer less well made shoddy bit of tat.

Cameron, I reckon the body itself is going to be fine, we have simply not replaced enough of the gaskets and o-rings. Metal tap may well be a plus but given that our plastic tap is probably 20 years old already, it has given pretty good service.

I think I'll try and chase up new tap. If I can find a metal one then well and good but failing that a new plastic one will probably suffice. Just make sure that everytime we change filter we renew all the gaskets. Easy peasy.

btw...I found this pic. It shows the knurled knob I spoke of but it calls it a 'primer' not a fuel cut off, so I'm back to being confused. Bowl on ours is as per yours, not slab sided but dished.

Re: Help! Leaking Injector Pump

Resurrecting on old thread, but I just recovered from a similar situation with my Volvo injector pump. I got lucky though, as my pump was a little easier to work on than Hartley's. My symtoms were:

Engine fires right off then slowly dies. Takes extended cranking to get engine to start. Our small pressure pump to our diesel heater was also losing it's prime. I suspected that we were losing our prime to the injector pump. Further examination showed that the top of the pump was wet with fuel after these hard starts, but hardly any fuel leaking while the engine ran. I think the combination of foamy fuel in the injector pump body was the cause of the fuel leaks on starts. Rather than pull out the whole pump, which had a linkage that I didn't have good access to, I decided to try and repair the leak with the pump in the boat. I consulted with a Bosch Dealer nearby who said it was common for these old pumps to start leaking.

I ordered the O-rings and some copper washers to see if I could fix the problem without removing the whole pump. They are numbers 18 and 15 in the parts diagram

Scrubbed top of injector pump with WD-40 and a tooth brush to clean it up. Removed fuel supply line to top of injector pump (17mm wrench). Removed injector lines off injectors and injector pump (17mm wrench) Removed fuel return line (10mm wrench), Remove oil filler cap assembly (it was in the way). Shove paper towel down the hole uncovered by the oil filler cap to keep crap from gettin' in the gears.

Remove a little keeper dealy-bob between two of the injector delivery nozzle caps. I think this dealy-bob keeps the center cap from turning when you're pulling off the injector lines because you can't get a wrench on it to hold it. 19mm deep well socket to remove each fuel delivery valve cap. There is a spring under there, but it doesn't go boing when you pull the cap. Under the cap is the O-ring and a copper gasket that needs to be replaced. Here is a parts diagram. Takes about 1.5 hours to disassemble and clean. Takes about an hour to put it back together.

Put it together this morning and it fired right up. No leaks. Hurray, we're going out to Hope Island to enjoy this weather while it lasts.

Re: Help! Leaking Injector Pump

erps,

Please post the Bosch part #s for the delivery pump.
I have a leak on my Bukh DV20

Under the cap is the O-ring and a copper gasket that needs to be replaced. Here is a parts diagram. #18 and #15

Can't read the plate on the back of mine it looks like PFR 70A8

Thank you
Bob

Re: Help! Leaking Injector Pump

rcaradimos,

I got the parts from Northland Diesel Service out of Bellingham WA. The part number on the receipt for the O-ring is 3410210007. The part number for the washers, 2916710602. Northland's telephone number is 360-676-1970. These folks have been in business for over 30 years and their business has grown. They have excellent customer service and their "injector pump" guy has been very helpful with advice in my past dealings with them.

Re: Help! Leaking Injector Pump

Not with me. I'll go down to the boat tomorrow and see if I can get it.

Re: Help! Leaking Injector Pump

Bob,

I couldn't read the Bosch number, but I have a number written down in my maintenance log. I don't recollect where I got the number, but I do keep track of part numbers that might mean something to someone in the know. This is the number I have:

0-414-173-998.

The Bosch pump is on a Volvo Penta MD-17C. When I google that number, I get a hit for a crossreference from a Volvo part number to the Bosch number.
