Did not find any new ones except one set on eBay. The rest are all remanufactured.
Mike I wasn't able to find this exact injector but Summit Racing offers an alternate part, TFXÖ, 24 lbs./hr., 14.4 Ohms Impedance, 12 V.

Anyone know if this is a reliable replacement for an 85?

I think the 85 32v needs the barbed top on the injectors ? (same as 84-86 16v cars)

Not sure what you mean by "barbed top" John. I know the 32v injectors have a slot cut in the top for the rail clips. Is this what you mean? There's no hose barb on these, they have O rings.

All 32V cars run the injetor rails directly on topn of the incectors with the O-ring seal and clip holding the injector to the rail. The barbed hose fittings are only on 16V car.

The question remains as to whether these Summit Racing injectors, which they claim directly replace the injectors Mike cites, are really compatible? Just hoping since a complete set is running about $350 and I think I'm going to need to replace mine very soon.

I am running the M-9593-AA302 ford injectors. The AA designates that it is the EV6 style all plastic body. I no longer see these listed in Summit but you can still find them on Amazon and the like. these are almost direct replacements. The need to have the clip groove cut in the bod to accept the rail clips. Search should find threads referencing the mod required.

No problems with clearances needed for the EV1/EV6 adapter?

the M-9593-AA302 is actually an EV6 all plastic body injector with the EV1 style connecter so there is no adapter necessary.

Thanks *very* much Simon, that didn't jump out in the research I did, I figured it was an adapter.

So no clearance issues, compatible and about $100/set cheaper than the Summit set. I think I can manage cutting the grooves

Best Regards,

Does anyone know how long the gauge should read pressure after ignition off? If it fails this test, what would be the diagnosis?

Per the manual it should maintain a minimum of 1 BAR at 20 minutes. If it drops below then you need to determine where the pressure is bleeding down.
Leaking injectors, leaking diaphragm on the FPR or Dampers, bad check valve at fuelpump…
