When I cleaned and tested my injectors, I used a less flammable fluid - I used marine stove alcohol which I just happened to have and later carb cleaner or was it kerosene? My setup was even more Rube than barri's

As barri said, the pintle caps are easily replaced (he helped me when I first did mine). I bought mine at dealer for low cost (I don't know if they will have yellow ones - does it make a difference barri?). I removed the screens by screwing in a self tapping screw and then pulling it out using vice (like pulling teeth!) I cleaned the screens in our el cheapo jewelry ultrasonic cleaner.

And again as barri said, make sure you get the proper injectors for the 3.5 - Some remans come from asia so the yellow ones may be available. Those on line ones are not always Bosch - I read where others ordered and did not get Bosch. There are many on-line places selling reman injectors so check around. BTW, none of these are really rebuilt - probably just cleaned and checked for flow. If you have the time and don't want to do it yourself, I would just send existing ones to someone like this and let them install the pintle caps and new hoses. My 1972 vintage injectors seem fine.
