Injectors ????

Can anyone help me to identify these injectors.

I bought them along with a Rover twin plenum I intend to fit to my 97 500HC Griff, they are allegedly new Jaguar injectors but have been around a while, hence the rust on the collars.
They have no numbers or markings on them at all.
Reading some of the posts on air intake/fuel upgrades I've decided to do the following.

Rover Twin Plenum with centre pull conversion
41mm Steel Trumpets
Stainless Steel steel Y peice (Plenum to AFM)
Bosch AFM
Upgraded injectors
Smooth bore silicon Filter to AFM
MA Tornado Chip & Rolling road re-map

The car is standard at the mo

Any Thoughts Apreciated

They look dirty, rusty, and have clearly been fitted. I strongly doubt they are new/unused. My limited experience of injectors is that they all have part numbers cast in small writing on the plastic body. If you're sure there are no markings on, I suspect your best bet would be to measure the resistance to find what type of driver they need, and hook them up to a fuel supply and see what volume flow rate they give. However, I suggest that unless you need something special and think these may be it, you bin them and go with a known quantity. Do you have any reason to think you are exceeding the flow capability of your existing injectors?

all injectors need to be matched to acheive ANY performance. I would suggest having them flow/rate tested as suggested previously unless history is KNOWN!

clearly old/used

I thought any marks on the Plastic would be moulding reference marks, however they have "Ram" and "B" and 9 or 6 ?
They have been fitted but not run, so if I can identify them they may be useful & as new ones aren't cheep....

Have to say I think you are flogging a dead horse there unless you want to gamble the money to have them checked and cleaned. You can't tell what condition the insides are in unless they've been kept in a clean dry environment, and the outsides seem to indicate that isn't the case. In fact from those pics they look rather manky. Any idea what Jag they came off? I know somebody who bought a sack load of old but unused Jag injectors and was almost giving them away, but the flow spec was too low to be any use to me. Just knowing they're off a Jag doesn't mean they're any use to you.

Look more like the noozle on the end of my garden hose to me

But what do I know.... F all
