Replace the bottom O-Ring piece with a new one from menards, I will get exact part number, but the Precision one does not fit.



With a little pressure and twisting motion push them in.
Pre lube with silcon or WD40.



Make sure you use 4 washers as spacers, or find spacers that fit(which I couldnt hence the washers)


Next lube up the upper O Rings ( stock Precisions fit). Then press the Rail on top of the new injectors.


Next put spacers on the Rail holders.




Bolt the rest of the parts up and you are set to go.

 

nice!

 

do you have to have these washers? whats the significance? and is that a large black seal above the small seal on the very bottom of the injector? i think pte sent me the wrong washers.

 

You may want to position the injectors with the plugs pointing strait up like stock. Many injectors today have have certain spray patters (they dont just spray in a round pattern like a sprinkler head) and need to have the injectors positioned accordingly.

 

does anyone know the part number to the large injector seal that goes on the bottom?

 

Great write up! Remember to lube up the seals very well, tight fit so its common of them to tear. Theyre like $20 shipped for a set so its a pricey dumb mistake! Be careful!

Cheers!
