School me on injector O-rings

[saburai]

Hi gang! Getting ready to put Diego back together. I need new injector O-rings, can I just walk into AutoZone or Napa and ask for them as such? Alternately, is there a specific size that I could get from an industrial supply or good hardware store? Many thanks...

They are #111 o rings which are 7/16” ID and 5/8” OD. I buy bulk from McMaster Carr

Thanks friend! Can I just walk into the auto parts store and ask for injector O-rings for our trucks and source them there?

Probably, but you’ll get better quality going to a hydraulic shop and getting viton

I bought mine from Amazon. You could just get a return line kit from the parts house store if you're hurrying. You could ask for the return cap o-rings but I don't know if the guys behind the counter will know what you want.

I had to order a couple packs because they're 10 packs. Size 111. Slathered them with wheel bearing grease when installing.

Thanks guys! I'll see what I can find in this little one-horse town. Otherwise it's on Amazon...

THEWESPAUL, do you use lube during installation? I was told to lube with vaseline prior to installation to reduce possibility of tearing o-rings???

 

[Thewespaul]

I use Bearing grease on viton o rings and Vaseline on the conventional ones

When I've tried this, I always got a blank look and was asked what size they are and how many I need. I just take an old one in with me.

Thanks man, are the copper washers available on Amazon as well?

Just bring this back to the top, I found the O-rings in bulk thanks to chillman. Looking to find the copper washers on Amazon in bulk as well. Time is of the essence, so perhaps I'll buy a delphi return line kit. I prefer to have the washers and o rings in bulk...
