Fuel injector “0” ring question

[treedawg]

Is there anything special about diesel fuel injector “0” rings?. Can’t seem to locate replacements for Bosch injectors but I’ve got a large assortment of Viton “0” rings and I’m sure I can find one that’s very close. I assume the Viton rings should work if I can find a close enough replacement?????

A quick Google search pops up lots of results on Amazon eBay injector shop etc. for Bosch fuel injector o-rings - diesel or otherwise.
What do you have and where have you looked so far?
Those o-rings are critical for compression and fuel air mixture. I would think that guess and check at the sizes would be a last resort

Here’s a pic of the injector but I can’t find anything online that references the numbers on the data plate. Haven’t tried to contact Bosch but that’s my next step assuming they have a consumer help line.

No not really. I have four different o-ring kits, the only one that is special are the HVAC green o-rings.

Not to be stupid or anything, but where exactly is the o-ring that you want to replace? Is it on the low pressure side / high pressure side? Is it in the injection pump itself?

That part number (Deutz 04271701) is a common Deutz injection pump, $380 or so on eBay at the moment...The shim under it is a big deal as that sets the timing, and may need to be changed if you change the pump.

All the best,

So I should be good to go as long as they fit..?? I’m going to see if Bosch will help me tomorrow. They have a help line but I’ve got low expectations.

I pulled the injector “the part I circled” when I was bleeding the fuel system after sitting for 3 years without running. There’s an “0” ring sealing the injector in the base. The motor runs like a champ once you get it going but it’s losing prime overnight. I haven’t been able to locate the leak but I’ve replaced the fuel filter, all the hoses, clamps and inline fuel between the lift tank and lift pump.

Forgot to add pic of the part I removed.

Thank you….!!!! That says fuel pump but I’ll give them a call tomorrow either way. Maybe they can steer me in the right direction if that’s not what I need.
