Went to the hydraulic shop and bought everything I needed to build my own injector pop pressure tester and it works fantastic. No need to cut drill weld a 4 ton hydraulic jack when you can get a hand pump or grease gun which delivers easily 3000, to 10,000 psi depending on which pump you purchase, or have hanging around your garage. A liquid filled 5,000 psi guage will cost you 20 bucks with a 4 inch glass front. I brought one of the injectors with me and the gentleman made a 6 inch hose with the correct end fitting for the injectors and an end to thread into the "T". A normal flexible grease gun hose will handle 3,000 psi check yours out I was very suprised to find this fact out from the hydraulic shop, it should be written very clearly on the hose. You should also install a bleed off valve as after the injectors pop you will see there is still ALOT of pressure in the line. After using this contraption I put together with some help I found out it works Excellent. I will include some pics after my camera charges its dead battery.All the supplies at the shop plus the custom hose cost me $49.76, plus the cost of the hand pump i bought from them. My next trick is fabricating my own shims for the injectors, cus if they can do it so can we
