View Full Version : Fuel Injector with Broken Tip -- Useless?

I dropped a ziplock bag with a set of injectors while getting out of the car. One of them landed on the green tip at the nozzle end and the tip broke off.

This set is useless, isn't it?

No. You just need another spray tip.

Jim,

I know the O-rings and clips are readily available to replace, but I thought the "tip" was considered part of the injector? After some checking, looks like it is. Can't purchase a tip separately anywhere. EDIT: Nevermind, it looks like there are a number of sources for 'pintal caps.'

Have you ever swapped an injector tip from one to another? Any 'tips' from someone who has a lot more experience than some of us?

Thanks,
Stu

Under Real OEM, I don't see the E36 injector tip available separately:

Also, for the E30 (M20 B25) I don't see the tip as available separately:

I've been told that RC Fuel Injection sells just the tips alone but I havn't verified it. I'm e-mailing them right now and I'll let you know. I'm also in need of 24v injector tips.

You mean you broke the pintle cap?
You can buy them on ebay.

Yep, pintle caps are replaceable.

Might want to run them under hot water to make them a little pliable, they are easy to break when trying to install them.

you can get new tips at napa.

they affect the spray pattern pretty significantly so I wouldn't use broken tips. Plus I think they cost less than a dollar each.

Looks like RC Fuel Injection sells them for Bosch injectors for around a buck each, won't hurt to pickup spares. Thanks for the heads up.

I was just at NAPA, not only did they have no clue what I was talking about when they finally found them, they told me they only sell them in a kit with the seals.

these are the correct caps right?

sorry that your napa sucks. When I went there they brought out a whole box of differet caps so we could find the right ones.

also if your injectors have broken caps chances are you should be replacing the seals anyway..

is there a problem with taking the pintle cap (tip) off of an injector from a car in the pnp to replace a broken one?

They sent you the ones like the ebay link? If they did it will work and have a better spay pattern than the brown one in the pic.

Ship them back and get the design 2's off ebay. But I think they might still work. Some one correct me if I'm wrong

so i took out my injectors for the 1023 time and replaced the fin-style pintle caps with blue non-fin style pintle caps. it was a pain in the ass but it was worth it. however when putting the injectors back I must have broken one of the top seals because it is SPRAYING fuel hard from the top. where can i get a new seals? is there any place local I can get them so I can try to fix it today? dealer maybe?

today was a great day, car started up and idle'd smoothly for the first time in months =D

Go to any parts store and if they don't have them have them check for 5.0 mustang injector o-rings

Try and get ones from a mustang. I believe most Bosch injectors are the same.


I got mine at autozone.
