injector id?

[jpryorx2]

can anyone tell me what these injectors are so i can figure what to buy? after waiting 8 months for a set of cb injected manifolds they had major clearance issues so i ended up buying a different setup at a swap meet that uses these injectors and fuel rails.i'd perfer to just buy new injectors so i have all the info on them but will need the same physical size so the rails mount properly. the number on each injector is b280431250/1 i have searched for 2 days and can't find anything with that number
thanks

forgot to mention the measure out at 13 ohms if that helps to narrow it down

What do the manifolds look like where the injectors enter them? Do they hug those o-rings or do they hug the body of the injector itself? You should be able to pull the injectors and measure the length of them, also you'll need to confirm the diameter of the o-rings, CB stuff uses 14mm top and bottom. That is a pretty common size in the domestic world. Some of the import cars use 11mm o-rings. Most injectors sold reference the o-ring diameters and the total length, so just find something that matches what you have. Most ECUs play nicest with High Z injectors, those you have there, are high Z's.

There should be a pn on them some where, you can use that to cross reference them to get the specs.
