She's a runnin!

I think it was that wire dangling from the fuel rail.  The one that had a conveniently corresponding socket on the wiring harness for the plug at the end.  Maybe.   Well, Ok.  Probably.

Thanks fer the help kids!

Some of the later E36 M42 injectors used a sort of air injection into the fuel injectors in an effort to reduce emissions:

This air injection is just stupid and prone to fail.

I have a quick question regarding injectors:

Currently I'm cleaning my spares which I won't use for a while. After cleaning should I lubricate them internaly for storage? I don't think it's ok to stay for a long time with cleaning liquid inside them.

My 318iS (chip, throttlebody mod, intake mod, intake pulse chambers, cold air intake, richer air-fuel mixture, no fuel pressure regulator tho, exhaust is without any cat). Engine will be stock internals. And only for Sunday/track use. What would be the best injectors performancewise for me ? I dont care about fuel consumption, and white/black smoke or nasty smells. :D Ah also, im probably going on MegaSquirt some day also.

Bosch 0280155702 #22 or Bosch 0280150947 #24.5 or something else ?

I can put better fuel pump and regulator if you think thatll help anything. :P


Opinions please. ˇˇ
Im soon getting to that phase and need to decide what injectors to use.
Thanks.

how many lb/hr do the yellow ford 302 injectors flow?
These should be 19# injectors. Depending on model year they'll either have EV1 or EV6 design. I think ford kept using the 302 in the explorer late into the 90s.

These things are dime a dozen in the junkyards. Seriously, every V8 Ford from the late 90s has these. Buy them used at the JY and have them cleaned or clean them yourself if you really care.

These are #24 injectors from a 24 valve Ford taurus from the late 90s.

Why would you want to change injectors for 5+cc's?  I just had 2 sets of stock injectors tested and cleaned.  Both sets ran 204cc's.  Go have your inj's cleaned!

Mine are for sale. PM me if interested.

I just bought a set of injectors on ebay, pictured below.



The stockers are these.  So there's a small increase in fuel flow with the "new" ones (6.25% more).  tjts1, you said you were running the 155 712's?  Those look to be LOW impedance units (2.1 Ohm)...is that right?


I will be interested to see if this cleans up my idle & evens out my power band like so many others have reported.  That sure would be nice!

The new injectors are 4 hole and newer. The idle can improve along with fuel use.  The DME seems to adjust to the flow rate just fine.
 I use the 280 155, 715.  for a lot of the Bosch style cars,BMW, Volvo, Vette, Ford crap etc.

OK, is there a final, DEFINITIVE answer about needing to modify anything to fit 155 injectors?

It seems that, from posts here, that washers & filing are not needed...they fit fine with everything stock.  Is this true?  The drawing comparing dimensions indicates that the EV6 & EV1 units indicates that the EV6 ones are ~3mm shorter.  Has anyone checked to see if the bottom of the injectors are fully engaged in the lower manifold when installed?

If they ARE too short, the only proper course of action would seem to be filing ~3mm off of the rail mounting points (easy to undo with washers at least).

Usually, you have to remove the old injectors , one by one as they are stuck in pretty hard, the seals are beat, etc.
 The 715s are a little shorter. Placing all 4 on the rail, locking the retainers, ATF on the new seals,  slide the ass. in to the intake.  The seals fit in the  injector cylinder a little higher than the orig. but the seals are not slammed against the bottom. I have not had any issues or do overs.  WFM. <

I have done it and you do not need any washers or filing, they sit and worked fine for me without any other modifications.
