intake off.
I have the upper and lower intakes off my GSL-SE and wanted to know what you recommend doing/replacing while I have them off. Here is what I intend to do and maybe you can let me know if I missed anything.
1. Clean everything and remove as much carbon as I can.
2. Install pineapple racing sleeves.
3. Replace all vacuum lines and fuel lines where possible.
4. Check for any loose wires/grounds.
A few off the subject questions:
1. Oil Metering pump and lines-----Not sure if I should continue to use the pump or if I should pre-mix. The lines are real brittle. Can I use fuel hose to replace them? Shoule I remove everything and pre-mix?
2. There are a few vacuum lines that I don't use anymore like air pump, ACV, sub-zero assist, etc. I want to cap them off. What do you guys use? I don't want to plug the vacuum "hoses", instead I want to plug the vacuum lines where they originate from the manifolds.
Thanks guys,
Mike

1. yep

3. if you have it apart that far, replacing the injector seals (upper and lowers) is a good idea, and actually sending the injectors out for cleaning is good too. inspect the pulsation damper. i find these dont fail very often at all, but if/when it does, you have fuel leaking on to hot things, so keep an eye on it. i also find that the factory mazda fuel hose and most of the vacuum lines even at 25 years old are better than replacments.
4. yep, as long as your in there, its easy to clean the ground
1. the metering lines only break when you touch them, if you dont touch em, they wont break. if you wanna replace em, buy new ones, or make something out of OIL resistant material. id keep the metering system, premixing in a street car is lame.
2. vacuum caps. 3.5mm try to get ones without a seam, ones with a seam occasionally split.

Thanks, I appreciate the advice. I bought the standard size vacuum caps. I didn't even know there were metric caps. I hope these work. Local auto part stores won't have the injector seals, will they?
