Greetings,
I was under the hood last night fixing a PCV air leak when I noticed a lot of ticking. I pressed my finger over the #1 (driver side and furthest away from firewall) fuel injector and felt a hard pulsation. I compared this to my other injectors and two were not as severe and the other five were very light. I took down the numbers of the injectors and posted them below. Light blue color top.

Right Side
060 667
A symbol that looks like this in a circle (|=|)
280150759

Left Side
E8TE-B1C B

I believe this is out of a 1989-1990 Ford F350???

The Chevorolet dealership gave me two part numbers
Bosch 17111961
Lucas 10108481

I don't know what my car came with and there are obvious clues that show that this car has been worked. I have .030" over pistons. My fan come on at about 218 degrees F. I have a hot idle stall issue that similates a roller coaster and according to this forum is a sign of going from closed to open loop. I have done the heated O2 sensor mod as my O2 sensor is located at the collector.

I believe I need new fuel injectors. Accels ACC-150824 (24#) from Summit are a "NO" according to this forum.

Also, I hit about 115 and she falls flat on her face. Let me know

I'm taking them out! I found a fuel injection shop here in Connecticut MARREN FUEL INJECTION in Oxford.

Their website is injector.com

I'll let you know what the results are next week!

The specs on the 1989-1990 Ford F350 injectors flow the same 22#'s per hour and they are Bosch.

One of my co-workers is hooking me up with 12561462 or Bosch 0 280 155 931 set of 8 for $50.

Delphi / Bosch
28 lb / hr Injector
Part Number 12561462 (Bosch # 0 280 155 931) - This is a LS1 factory GM injector.
Static Flow Rate: 28 lb/hr (294cc) @ 43.5PSI (300kPa)
Fan spray pattern for superior atomization.
High pressure capability
High Impedance / High-Z

This is going to be fun or a disaster! Wish me luck

 

28# injectors installed and the car runs great!

 

So your pal hooked you up with 8 injectors for $50? Nice! How much was the install if you don't mind me asking? Did the installer need to tweak anything? I would've thought 28# is a lot, no?

 

I have a set of these (0 280 155 931) I bought a few years ago from SLP performance in NJ. They are listed as 25lb/hr and I believe they were removed from crate engines. Not sure but i think they were removed from LS1 motors! (?)
I haven't installed yet. Did you have to adjust fuel pressure or did you just drop in and go?
Glad to hear it worked out so well......

 

I just dropped in and go. My fuel pressure is currently set at 42-45 psi. I used the installation instructions on this site without the removal of the valve covers. NOTE: Purchase fuel rail o-ring kit before assembly otherwise your doing this installation twice. Advance Auto has them for $8 GP Sorenson 800-9211 GM P/N 17111696.
