supercharger pulley installation

ok im about to install my new pulley but im not sure which way it goes none of the instructions really make it clear what i mean is one side of the pulley is flat and one side is curved inward so which way? also when i took off the plastic engine cover i noticed the lines runing on top of the supercharger the fuel lines and one was leakeing they both feel sort of loose how could i tighten them?

my 2nd problem i just realized is that i cant break the nut on the pulley loose how can i get it loose or stop it from moving(the belt isnt on and wont fit on)

What type of pulley puller are you using??

If you are using a Thrasher or South Florida Pulley, the flat side goes to engine. Thrasher even has their name pointing out.
As far as the nut goes, used inpack. Sprayed it the night before. Came right off. Let's see what everyone has on that.

yes the pulley and puller are from zzp i dont have an impact wrench is there any other way...i need to stop the nut from spinning somehow...

Is the issue that your pulley is spinning while trying to loosen the nut?? If so, wrap your old sc belt around the pulley and grip it with a pair of vise grips. This should hold the pulley in place while you loosen the nut. It shouldn't take that much to loosen it. Mine came right off with just a 21mm wrench.

i might try something to that effect... my old sc belt wad destroyed because autozones pulley got stuck

Let us know how it turns out. One pointer on your pulley install-- be very careful to exert an even amount of force on the puller when removing the pulley. The M8 studs have a tendancy to shear off if you really crank on it. Good luck.

Just get some rubber gloves on and hold the pulley by hand and have a buddy try to losen the Nut in the center on the pulley...the nut does not hold the pulley on, it has a hole in the center of it and it is just a breather nut....also make sure you use alot of ANTI-SEIZE.

I got it off got the new one installed and now im hearing a sort of racheting sound and a small sqeel from the sc snout i read that the coupler goes on these could it be that??

Squeal could be caused by not having the pulley completely seated. It has to be flush with the end of the s/c shaft. If it's off even a little bit, the s/c belt won't align correctly.
