Fuel Injector Shipping Caps?

Hi All,

I'm getting ready to install fuel injectors that I purchased from FiveMotorsports - the 19 pounders for my '89 in-line-six. There are tan caps on the injectors - on the nozzle end - and I'm not sure if they are shipping caps or part of the injector. Here's a picture of the new one. New one is center and two old ones I pulled out. The left one is the original and the right one was installed a couple of years ago.

There is a previous thread on this but wasn't sure what was the final consensus.

I tried pulling one off with a pliers and it's hard as a mother to pull off.

Thanks for your help!

Not too sure about the cap on the end.
BUT...what is the advantage of going to the 19 pounders?

Thanks.

The 19 pounders are the injectors everyone recommends for a stock engine. Higher pounders for a modified engine.

I purchased them via ebay and saved about $35.00.

Don't take those off. They aren't shipping caps, they are part of the injectors.

Thanks PaulJ!

Luckly I didn't do too much damage to the plastic - just a few small cuts on one. The plastic tip really throws you off because you think that only metal should be down there since it gets so hot and the ones I pulled out were all metal tips too.

So far is going all smooth.

Thanks for everyones help!
