got my injectors back from RC engineering I had some trouble getting them to seat when I was reinstalling them.
When I started the truck I could smell strong odor of fuel, after investigation it turns out the injectors are leaking around the seal where they go into the lower intake. upon removal I noticed that I have 2 different size seals can anyone help me out with this. This is what they look like

Suggest going to dealer and getting new ones for your Year/Model.

There is also a plastic cap type of thing that fits over the tip of the injector.
If this is missing they can leak also because it increases the diameter of the injector which the seals need to snug against to seal.

I was trying to avoid them again. They keep taking my lunch money. does anyone have a diagram that shows what all consist of a complete injector set; injector, seals, order etc...

It looks to me like someone sent you the wrong seals. I'm pretty sure the bottom one in the first picture is the correct one (based on other folk's pictures). Actually, I take that back, as you did not post which engine you have. The bottom one looks correct for the 3vze. If that is the engine you have, my condolences for having to tear the intake apart again to get those injectors.

ordered all new seals only $100 this time.

Update; took intake off, replaced all the seals for the injectors (again) put everything back to together and fired it up. no leaks, I put about 100 miles on it today and could start to smell fuel. none of the injectors on driver side leaking, from what I can see the front no 1 seal is leaking. cant tell about 3 or 5
Looks like I am pulling the intake off yet again

Am I missing something on getting these things to sit down and seal?

When I did my injector o rings I tore one ring putting back in. Put some lubricant on the o rings before putting injectors back in. I snagged one on the plenum and it caused one to leak gas real bad. I got the o rings for a few bucks at auto zone or checker.

I've always used silacone to lube them before installing. Have done many different vehicles and never a leak.

I just dabbed my finger in a little motor oil and lightly lathered the rings. Seemed to do the trick the second time.
