Step 1: Materials
Depending on your project you might need specific tubing, fittings, and etc. Which I will not be addressing here.
Step 2: First
Drill holes in the end cap. I drilled two and then remembered that I needed three. One for in. One for out. And One for my pressure gauge.
Step 3: Prime & Glue the Parts
Prime all the parts and glue them together.
Step 4: Thats It!!
I mine is totally crappy. I was so pissed that my first attempt didnt work I whipped this up and started using it.
