    I'm putting together a remanufactured engine, putting it in an 03 ram 1500 4x4 4.7. My existing fuel rail was severely rusty. Found an ram & a grand Cherokee in local boneyard & the Cherokee had the better rail, so I took that. I noticed one of my injectors was cracked, so I grabbed an injector from the Cherokee. Looks identical.

    2 sets of #'s on mine are 53032145AA & 2262Y01770

    2 sets of #'s off Cherokee are 53032145AA & 2149W12514

    Same plug runs them, but now I'm scratching my head & asking if its ok to use the 2nd injector. Anyone with knowledge please help

    Here's a pic, both have 2 little holes in nozzle [​IMG]

    the 53032145AA is the chrysler part number. you typed them both the same...so i'm assuming they are both labeled 53032145AA. As far as the other number...probably just a mfg number...or serial #. pretty irrelevant. If they all have 53032145AA, you're good to go...or at least as good as you can be with junkyard fuel injectors.lol

    Yes both the 530 #'s are the same. So that is good news. I'll use it. Spray through nozzle looks the same, in the process of cleaning them, hooked up to a can of carb cleaner with modified Schrader valve, then battery charger for power supply lol[​IMG]

    Thank you very much sir for getting back

    And yeah, I think the Cherokee was a little newer then my 03 ram, so that's the better injector then all the rest lol

    Yikes, I have a can of tb cleaner to. Done now though. I watched like 5 YouTube videos, & I think 3 of the guys used brakeclean & the other 2 used carb cleaner. I thought the break clean was a bit much, so I went with the carb. Any reason you can think of why I couldn't give newer fuel rail a little paint job, or should it be left alone. I ask cause it doesn't look like normal steel, maybe its galvanized, but the one I got from boneyard looks 80 times better then my old one[​IMG]

    when I was replacing my intake manifold gasket's on my 3.5L, I found 3 of my injectors had cracks in the plastic body. I was a little worried, at first, but they didn't leak before, and they weren't the problem before, so I just cleaned them up, & reinstalled them. I watched them for awhile, but they didn't leak, and the engine rus fine. So I wouldn't necessarily be overly concerned with a cracked body on those things, if they don't leak.
