O-rings

[Dieselmaster]

I'm being to lazy to go look right now.

But what size are the o-rings for the High Pressure lines under the fuel filter?

TIA for the help.

Are these the right numbers??

Or you can go to a hydraulics shop (Parker Store, etc) and ask for o-rings for #5 oring boss fittings for the heads, and #6 oring boss fitting sfor the HPOP.

Thanks much! It's always good to know there are other choices.

You don't want to use the cheap hardware store o-rings. I have that $12 o-ring kit from Harbor Freight (or whatever it cost) and I've used those o-rings too many times, but I've been warned not to use them and I'm on borrowed time. Just get the good ones and be done with it.
