What's this injector?

OK...So everyone please have your "I told you so"'s at the ready.

I went to install the Beck Arnley, and it didn't even fit properly! The short explanations; shorter nozzle means injection occurs much high in chamber (if not in injector channel itself) and very slightly longer chassis so with the Beck Arnley bushing, which doesn't fit the hole sufficiently anyway, the injector sits higher and because of the single bolt/ring securement on the 450SL it will mount at an angle!

Not that they care, but I will be contacting Beck Arnley also. This may work for other installations....but not this one.

Back to a good cleaning with mine. I'm looking at these folks, unless someone has some concrete better experience somewhere. www.motormanfuelinjection.com/Bosch-Fuel...ctor-0280150036.html

Surprising because my mechanic mounted them on my 350 SL 4.5l from 1972 and the engine starts. These injectors are however sold as being 100% compatible with Bosch 0 280 150 036.

Get reimbursed and have your original injectors reconditioned if possible by an ASNU service provider. And wrap the injectors well so you don't break the connectors as they may have become brittle over time.
I can't open your link (host down).

I would expect that it would fit well enough to work and perhaps I am being unnecessarily picky. The injectors blast a mist of fuel twice per intake cycle so perhaps the injection occurring slightly higher in the chamber (above the chamber?), and maybe with a slight mis-alignment, won't matter. I also could be wrong in that perhaps when the injector is completely tightened down it will straighten out naturally, although there was still play both around the nozzle and around the gasket...unless you used the stock MB gasket instead of the Beck Arnley supplied one, which would then have rubber extending beyond the injector nozzle itself...which also may not matter.

It's just that there were too many things adding up. I decided to take the risk with cleaning the injectors and hope that a before/after test will show an improvement and the vehicle will run better once installed.

Guys, a last time:

all those China/USA rebranded injectors are all of the same technology and I am believe that there is only 1 manufacturer for them: 3 hole instead of 1 needle. They might be even injecting the same amount of fuel in idle. However they do not perform the same when you change rpm and injection times. But that is what is needed to be compatible with Bosch injectors and that is what D-Jetronic ECU relies on. Fuel pressure and injectors wotk properly and then inejction times determine the amount of fuel injected.

I do not want to add more to it.
