Just picked up an 03 5.3 the injector clips looked a little different than what I am used to seeing, the number is 25326903 I can't find anything on them. Anyone know what they are?

 

they are mini delphi multec 2 225ccm or 22lb.. they are stock for gm 5,3 trucks 99-04.. what are you putting them in?

 

I bought the 5.3 from a buddy, only had 17,000 miles and was complete. I am using a gmpp single plane efi intake, with a 4150 style throttle body. I havn't picked up a cam for it yet still searching what to go with. I was hoping I had got lucky and they were the flex fuel injectors, but o well. I bought a blown up 6.0 swap that I am planning to build up on the back burner, going to put the 5.3 in to get the bugs worked out of the car and it back on the road. Going in a 69 camaro with a t56. I guess I'll use the ones from the 6.0, they are 28# aren't they? I was going to use its harness and all anyway since I have hptuners for an 02 truck. Thanks for the help, I had looked all over for that number and could only find one post of someone else wondering what they were.

 

the .. 6.0 28's are only when you have 58psi fp. at 43.5 they only flow 23.5lbs

 

Thanks again for the help

 

Anyone have the wiring digram on them?
