What are you guys using for shut-off valves? The cheapest one from McMaster-Carr rated for 2000psi is ~$35 (4024T71).

Modification
I am in the process of building a pop tester based on Cornblatt's design. However, I read in some MB manual that the valve functions to control the rate at which injector pressure increases thus allowing a more accurate reading of pop pressure. I'm thinking that to accomplish this, the sequence should be: bottle jack -- valve -- gauge -- injector. This way the gauge reading will be the pressure at the injector side.
The pop pressure procedure would then be: 1) Pump bottle jack with valve closed. 2) Slowly open valve to increase pressure at the injector side. The gauge should then show increase in pressure. 3) If pressure is not enough, close valve, pump jack and then slowly open valve. Repeat until injector pops. I will build mine this way and let you guys know how it turns out. The only problem is that I am having difficulty finding 6mm OD Merc injector lines. Another option is to obtain an old delivery valve holder so I can temporarily use one of the injector lines on my 300D. Anyone have a spare injector line or delivery valve holder I can buy? I have 5 Monark nozzles from C. Sean Watts that I'm itching calibrate and install. |

i tried following this article and I get not pressure at all at the injector so which means i screwed up somewhere. i have no leaks any where but just getting a stream and low pressure. what exactly do we modify to the bottle jack?

A Macgyver amongst us... Super well done!

Fantastic Write-Up!
When I see ones like these it both inspires and intimidates the hell out me from submitting anything half as good. I'm anxious to build one.
Question... Where do you find a shut off valve such as your's that's rated for 3000 psi? I can only find them to 600 at best. |
How much does it cost to build?

What about making opne for the old type petrol none electric injectors .Would the idea be the same ?

Is there an advantage to using a liquid filled gauge vs a dry gauge? My Bosch pop tester came with a couple of dry gauges but I was debating getting a liquid gauge.

A Very Good Thread !
