Measure your leakdown and flow pressure with this gauge.
When setting up a mechanical injection, you need to set your leakdown percentage.
This gauge enables you to do just that!
You can check your opening pressure and cracking point of your bypass valves, secondary valves, and Hi Speed lean out valves.
This gauge is included in my Set Up Kit for setting up a Hilborn or Enderle Injection system.

INSTRUCTIONS :
How to use Alkydigger'S Leakdown Tester to set THE Barrel Valve.
- Hook the outlet hose to your inlet fitting on THE barrel valve.
- Cap off the other two check valves.
- Put air hose with at least 100 psi on to the leakdown tester.
- Adjust the left gauge to exactly 100 psi.
- Read the right gauge for what you want the Leakdown % to be.
- Make adjustments to the connector rod between the butterflies and barrel until you achieve the desired leakdown %.
- Open and close the Barrel Valve several times making sure that your left gauge did not wander off of 100 psi.
- If it did, then re adjust the leakdown percent until it is what you are trying to achieve.
- Richer ( more leakdown) slows the idle DOWN Leaner ( less leakdown) speeds up the idle.
Call Alkydigger for suggested percentages for various combinations.
