VW Beetle L-Jetronic Fuel Injection

We’re setting up an original usa L-Jetronic fuel injection system. Could anyone tell if the spray pattern is normal, or should it be wider? The injectors are new unused aftermarket versions, as seen on the picture in the end. Just wondering if those white plastic thingies should be there, or should they be removed? I mean, they do affect the spray pattern, don’t they?

OH Yeah i forgot remove the plastic it not suppose to have none jus the tip of the needle valve sticking out and the outer rim to guide the spray …………………good luck
NO that injection system also comes with the Napz (Nissan Z18,z18e,z18et)……and also your fuel spray is very poorly atomized, it must be misty…………….
And can u plz tell me all the sensors you have connected to make it work cause mine is not running ……only pre ignition
I thought that injection system only came on older BMWs
Thank you
You’re supposed to get a cone of fine mist or droplets of fuel. Those injectors you have just squirt like a water pistol, not good for atomization. Results in poor fuel economy and probably a rough running engine.
