So, o-rings, where can I get a set of just the o-rings? I have the new copper washers, return caps and hose, just need the o-rings, but all the auto-sites I've visited so far come up with the complete kit even if I search just for the o rings.
I'm not in a hurry, not even close to putting the engine back together, just looking ahead.
Thanks!

McMaster-Carr, viton #111 o-rings
They come in a bag of 50 for like $6 +shipping, will be enough to do 3 complete sets of injectors.
If you search you can find a direct link that someone has posted in the past, I'm just too lazy to look for it right now.

What do you guys think of these eBay pop-testers? I'm a bit leery of stuff shipping from/mad in India, but there doesn't seem to be an affordable local option and they do have a lot of good feedback:

and? you could probably do it with a old grease gun as well (although i think it will be more prone to leak).
all you need is a small diameter piston and a lever to press on it. a reservoir of some sort, and a pressure gauge.
i make almost everything i use... so just a suggestion.

Be careful with the shims.... They ALL have shims.... If you only pulled a couple out, you probably have BB codes correct? The shims get stuck to the body really easy, and a small blast of air or brake cleaner will free them up, just dont lose them, or your screwed.
When you put them all togther again, use a light oil to lube the parts, and make SURE there is no specs of anything when you put them back together, keep things as clean as you possibly can... I Torque all my caps to 40ft/lbs (spec is 35, but I have had even fresh lapped surfaces leak just a bit with 35lbs, I have never had one leak at 40lbs.)

Thank you for the torque specs, was looking for these before I put the injectors back in the truck.
