I'm guessing that it doesn't make a difference, but do any of you guys know why all my fuel injectors have different numbers? Is it a manufacturing date?

The top number is the actual part number. The bottom number would be a batch or lot number, or at least that's my guess. It would help the track things in case there's a recall or something.

 

Ok cool, that's kinda what I was leaning towards. I appreciate it! Watched a few videos on how to clean your fuel injectors and made my own little set up...actually worked pretty good!

Well, turns out I had to end up replacing 2 of my fuel injectors...glad I took to the time to check them out. Question now is....they were a PITA to get out and now with new rubber O-rings they don't seem to really "click" back into place. Any thoughts?

 

They really don't click in, for me it felt much more like a squish until it stopped. But don't do it dry, put a little fuel on them so the oring doesn't **** sideways and get pinched. Might ruin the oring or cause a leak.

 

Thanks for the input. I watched a couple videos and saw people use either a silicone lube or something similar when putting them back in. I'll grab some gas and see how successful I get. Thanks man!

 

I replaced #7 (giving me issues these last two years) this past weekend.

What a royal pain to remove. In 100* heat in direct sun.

Anyway, finally got them removed. I simply just pulled my dip stick out, and rubbed a little motor oil on the new O ring. Slid right in. Then just put everything back in place and started it up. With a flashlight I just watched to make sure no fuel leaked.

Then went for a drive, about 4 miles, and checked again for leaking fuel and it was dry in that area.

Score.

 

Yep...

Win.

 

I recommend using a bit of liquid dish soap or silicone lube (spray) on the O-rings. This makes them a lot easier to install and remain undamaged - it's a lot easier to feel when each one is seated when the rings are lubed.
