Hey y'all! New here to the forum but I wanted to run this by you guys. 1993 HO 4.0 and I installed yellow bodied injectors which I believe are 19LB Bosch units a few years ago. Doing some research because I was bored revealed a possibility that I should be using 24LB injectors because I have an HO? Can anyone verify this for me? Am I good with the currently installed 19LB or have I been running lean and should swap for 24LB?

**OK update... So I searched the forums and found a chart detailing fuel injector upgrade to 19lb injectors plus a Chrysler 4418850 fuel pressure regulator. Again if anyone could confirm either it would be awesome. Even better if only had to swap my regulator. LoL **

 

Mind posting that chart? I have a 90 and am considering swapping the injectors, and am unsure which ones to go with.

 

Yeah here it is.

 

** More info, my injectors are yellow and fat bodied. Part number on the side is 0280150989 **

 

Bump. Anyone?

 

You want 0 280 155 746 injectors for your 90.

 

What can I pull those out of?

 

Volvos

 

Thanks again cruiser. The WJ booster and master worked out great btw.

 

Glad to know you got the best info for your injector application bad_idea! But no goddamn thanks to being thread jacked without any information for my current question. I mean WTF?

 

Someone will chime in on yours in the meantime.

He needed guidance so he wouldn't get the same injectors as you do. Chill.

 

Copy cruiser. My bad. Long day. So.... I need different injectors as well?

 

Contact Programbo here on CF. He knows what you need and can likely provide them.

 

Ok. Thank you sir. Much appreciated. Sorry I'm a pain in the ***. Family trait

 

ain't bothered.
