Precision 680cc injectors?
I bought a set of injectors for my build, but I am unsure if they are what I paid for. Labebled "siemens deka" on one side, "L-65" on the other. All black.
If the L-65 stands for ^5#/hour then I am set, thats a little bit bigger then 680's. Anybody use these before?

Re: (J. Davis)
Most of the MSD/Precision pictures are of Rochester (Delphi) ball-style injectors. http://www.msdignition.com/fuel_4.htm
http://www.antimpower.com/injectorfyi/ (search for the rochester picture)
My 780cc Siemens (brand) Deka (model) injectors are visually different, although they are still the good ball-style. They are the Deka ID (but with a much shorter tip), http://www.synerject.com/fuelinjectors.html
http://www.autronic.com/page_files/injectors.htm (top pic - far left Deka ID's, far right Delphi's)
Just next to the clip's connector on mine is a 4-digit number (like 3472 or somthing, forgot). Whatever mine has is the code for 780's. If you have that number, I could find the list again. But I don't think that's a problem, since they list their injectors with a bias towards lbs/hr rating. 680cc is roughly 66lbs/hr, which would make that L-65 number apear as a 65Lb/hr designation.
FYI Seimens and Delphi are two totally seperate/independant companies from each other, they aren't rebrands of the other. The good thing is that both are known to have a very fine mist with a large spray pattern. From my research, I know the Deka's can maintain VERY high fuel pressures (as in 95psi+ constant, exactly what I forgot - with no decrease in longevity). Their only downside is minimal possibility of deposites sticking between the ball & seat, which isn't an issue if you have the injector screens, a working fuel filter, and good gas. 780's run fine on my d16, idles perfect and gets the same milage as stock 240's. [Boost project will resume when I get my beater running.]
BTW - the Deka ID's I have require a fairly tall injector seal, as well as dual o-rings (not needed, but a good idea). I can make you some if you like, since just shoving their long necks in the airstream isn't the best solution.

Mine came with no labling because the prev owner was a nog. Good to know I can sell them for a profit since my **** would blow up if I put anything bigger then 450's in it.
