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?

 

they're 680cc, I've got some MSD injectors and they say L-65 on the side too

 

Precision, MSD, all Siemen Deka.

 

Most of the MSD/Precision pictures are of Rochester (Delphi) ball-style injectors. http://www.msdignition.com/fuel_4.htm

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

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.

 

Wonderful information, thank you so much!

 

my precision 780s are the rochester delphi style.

mine came labled with precision turbo and engine stcikers though

 

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.
