You can buy a kit from RJM injection tech.
It has almost everything you need, and is inexpensive

^^^^ I did that when i did my 351, and it did not help. I ended up having to replace the injectors. Bought mine from rockauto.com. Ended up paying about 10 bucks less each than anywhere else.

For $20 and a gallon of lacquer thinner would it hurt to try?

the pintles will damage and never seal again. thats what happened to mine. and injectors are 80ish bucks a piece, and you cant test them, gotta replace them all at once.

Well, do as you please.

I think the 'F Rockauto' thread is in the 80-86 forum.
...But they have been good to me.

I suppose how long you plan on keeping the truck. For example I'll be glad to pay what I can knowing the new part works like it should, you can get the rebuild kit , but do you truly know if it will all flow the same again? If you do rebuild, get someone to flow bench them.

The RJM Injection Tech — Fuel Injector Service Kit will not fix a true leaky fuel injector, but only pretties it up... if you clean it. I know this because I have used this kit.

All it for is replacing the ring seals for the fuel rail, intake manifold; the cap that protects the spray tip from damage and the filter.

In order to fix a leaky injector, one would have to get to the plunger and valve spring. which you don't when when using the kit shown above.

BUT, if 20 dollars of replacement seals, filter, and a protective cap; saves you from buying 200 dollars of new injectors that you may have not needed due to a bit of dirt in the spray tip. I say give it a try. It has worked on my truck, and i would try it again before replacing my injectors.




TLDR: Give it a try. I did, and it worked.

Just a note: you don't need a 12v battery to make the injectors click open. All I used was a 9v battery and was able to blow out the injectors with it. 12v is over kill and will burn up your injector in your hand....
