replaced my injectors around april i think and the 4th one is wet around the base of it. (4th from the front) is the bottom nut just need tightend? cant get a cresent wrench on it. do i have to take of the fuel line?

Are you sure its the hold down nut and not the return line? Did you clean out the holes before putting them in? Most of the time you need to pull the lines to get to the hold down nuts.

just figured it was the hold down nut bc it just started leaking. its leaking all the way around it looks like its not the return line but ill degreas it and check tomorow

check the hold down if its tight, then you might have to pull it and clean the hole out

i started to take my afc house off and the flat head bolt in the top right was to tight to get off so i started to take off the return line then i dont have the next size up wrench that i need. sucks not havin the right tools for the job

yep thats true. did you end up getting the tap yet?

Has your afc been off? And the return lines a 10mm

i got the 10 mm dont have a wrech for the bolt down for the injector. it has been off i took it off a few time to put in the plate and mess with it. not yet brandon i was lookin at it and the piece that the pyro screws on with the threads on the out side is welded on the down pipe. can i get another or is that a special part?

the bolts for the injectors can be replaced. as for the pyro best to weld it up and just drill your new hole

the pyro with the probe screws on the other peice and that is welded in the down pipe. can i get another?

If your return line isn't leaking, and the injection line at the injector isn't leaking, then the nozzle could be leaking where it threads on to the injector body. You might have to remove the injector to see it if the leak continues. And the injector hold down nut can be tightened or removed with a 15/16" deep socket or wrench.

you can but it would be easyer to trill a hole in the other then thread it in instead of having to weld it, those manifolds are cast iron, you have to have a professional welder weld cast because there is alot of pre-and post heating the weld so it dont carck. (and that i know my dad has been a welder for 20 years and a weld inspector for the past 15)

When I modify these cast manifolds, I use a rose bud and get the cast glowing hot and turn the heat up on my mig welder and weld it up. I have done this several times and I haven't had any crack or leak yet.

yep thats the best way, pre and post heated
