List your pulley sizes for me:
Serp side =
Jackshaft =
Supercharger =
Also, I had tried the propane method and it didn't work for me. Thats when i pressurized the system and BOOM. There it was, super easy to see at that point. I had the propane all around that area too and it didnt blip the idle at all.
Here you go. If you have Prime then and order it today it will all be there for you Friday. I cant remember if the 2.5" is the inner or outer diameter but you get the picture. I'd just take a silicone coupler in to Home depot or the like and find the cap that fits. Drill a hole in there. Use a couple rubber washers and a nut and your done.
WARNING: Do not stand in front of this when you are charging it. Mine came out once and luckily it was facing a wall. It hit the wall at like 100mph. That would have hurt..lol. I scuffed up the sides of it so it had a little better bite and it never came out again. Hold on to it when filling it so if it does come out it doesnt smack your hand.
