I have a 1995 5.2. On the fuel rails there is just one connection. What size injectors are in the 95? are the injectors the same from a 96? I also have a 92 fuel rail set and a 93 fuel rail set. those fuel rails have a return line as well as a feed. Which is a better system? what size injectors did they run in 92? They have a yellow top if that helps. the 95 apper to be black or grey, as do teh 96. I am a bit confused on these injectors help me out.

 

94 and up have a returnless fuel delivery system. So this is a better system if you have a 95 because that's what the truck is set up for. Are your injectors bad? Accel makes a good matched set that will fit. I can post the part #'s if you need them.

 

part numbers would be a big help.
are the 95 injectors 24 lb?
what about the 96 and the 92?

 

I think that the stock injectors are either 19 or 21, but I was told that they can vary up to 15%.

Go here for part #'s :

The dodge uses the Siemens dekka type injector. As to the flow rate, I can't answer that. I went to a site called Five-o motorsports. I ordered a new set of Bosch type II injector rated at 22lbs./hr for about $250. Can't beat that price... Email the site with your info, and he'll match you a stock or upgrade set for a good price. He even sells high perf. , high flow injector up to 55lbs/hr for racing applications........

 

From the DML and Shane Mosley:

"I read the following from the Q&A section of the April 2001 Mopar
Performance News:


Q(5) I'm working on a fuel-injected combination and my dyno program
shows I could benefit from more injector delivery. What can you tell me
about flow rates of the injectors in your catalog? Also, if you have
the factory injector rates would be very helpful.


A(5) You should step up the injectors in something like only 25 percent
increments. The production V-8 is 24 - the MPP package is 30! Remember
that you must change the computer if you change the injectors; at the
least, it must be reprogrammed with the new injector values. Injector
rates are not as easy as one might think, but they go something like
this:

Engine Years Flow rate in lb/hr
Neon ( All) 23.9
2.5 Magnum 91-95 17.4
2.5 Magnum 96-01 23.2
4.0 Jeep 91-95 21.4 (Equivalent to Lucas 5207013 )
4.0 Jeep 96-01 23.2 (Equivalent to Lucas 5208005 )
5.2 Magnum 92-95 18.2
5.2 Magnum 96-01 23.2
5.9 Magnum 93-95 24.5
5.9 Magnum 96-01 23.2 (Seimens/Chrysler P/N 53030778)

Note that about 1996,
when the engine PCM computers went to the OBD-II standard,
all the Dodge fuel injectors went to a 'common calibration' of 23.2 lb/hour
