Need Help on removing the Lower Intake Manifold

Ok I managed to break off two oil injector lines(luckly I have spares). Now I need to know what one of the lines it. I already removed most of the vac hoses which did not break. But there is one line which I do not know what is. It hooks up to the LIM on the firewall side and goes to the brake booster. I need to know what it is please help. WHo has the best price on oil injector lines?

Sounds like you already answered your question; that is the brake booster line

THe best price would be the Junk Yard.... Find an N/A S3 or S4, the oil lines are the same for them... about $3 bucks at the junk.... found some myself... but be careful.... or you car use rubber hoses.... I use 2 of those it doesn't break...

Or if you want brand new.... MAZDATRIX has them for $23.(some cents) "per Line"... One oil injector line....

DO you all think I could use some silicone gasket maker to put the LIM back on the block? The old gasket shreded itself. Oh and Does anyone know who sells carb cleaner in large bottles. I need a butt load fo clean everything nicely.

Ok who has the best price for the oil injector lines. It looks like i will spend 40 dollars plus shiping and that is only for the two I broke off. Can I use a small vacume hose with a clamp(on each injector) for temporary use? I don't mind having to re-remove the upper intake later to put in the OEM ones.

Also where did you get the LIM gasket for five dollars? At mazdatrix it is like 25.

If your talking about the OIL lines that go from the oil injector to the metering oil pump.......NO, never use rubbler vacuum lines. The rubber will swell up and leak in no time at all.

IF you talking about the lines on the top of the injectors, that go to a SPIDER, then yes, use regular vacuum hose.

Back to the OIL lines on the injectors.........I got lucky at a local hardware store called Sutherland's, and found some 3/32 clear fuel line (heavy imphasis on the FUEL) that works like a champ. Its a fuel line made for small engines. Sorry I forgot the brand name, you wouldn't recognize it if I did. It's not that weak sister vinyl tubing, so don't think I talk about that.. I used twisted copper wire at each end to secure it. Much like saftey wiring it in place.
On a personal note: Dammit, I really, really, really don't wanna go to work today. Got a real bad case of the don't wannas

Is the brake booster line just a vacume hose? cuz it is prety baldy torn and cracked I have some big silicone vac line that i could put in there or does it run liquid. I think it is a vac line but I need to be sure and i lost my haynes.

$5......Maybe 5 years ago. Everywhere I checked wants $20+ now. The new gasket is weird looking too. Looks like 3 metal gaskets held together with 2 rivets. That's not what I took off. The new gasket came from MAZDA. Hope they know what they are doing.
