4.8l Replace Injectors With 5.3l

[Stevenduchnych]

Hi i have a 2001 gmc sierra 4x4 1500 with 220,000 km on it. I have 3 leaky injectors and i messed up another cleaning them. So my question is i have Delphi p/n 25317628 injectos but found some delphi 25323974 from a 5.3l for a decent price. I am considering replacing them all with the ones from the 5.3. Mine have 2 pin holes at the bottom but the other ones have 4 pin holes also mine shoot a straight stream and new ones are more of a mist.( i am thinking its because they are dirty and no good anymore). Can i switch them straight across is there much a difference really ?

not sure about swapping, but the spray should be a V shaped mist (better atomized), not a stream, which will burn poorly.

don't quote me but i'd think the injectors would be the same, ls motors are pretty much almost identicle minus a few numbers here and there
