Same basic kit as the above unit with more pressure capability (15 psi) for stronger lift pump setups. Use this gauge if your lift psi exceeds approx 8psi. With the increased capacity some fine resolution is traded off.

Complete control harness uses digital circuitry to cover all power supply issues and incorporates a non load carrying oil psi safety switch to ensure that pump does not run when engine is not running.It also includes a "one shot" primer function that energizes the pump for several seconds at key up to prime the fuel system at startup like most modern EFI vehicles do. There is also a manual push button to override the control circuit when bleeding filters!

Available in values of 1-9, but stocked in #5 and #9. These resistors are used by the pump assembler to fine tune the fuel delivery rate. For performance applications where gauges are used to monitor exhaust temps, a #9 will provide a slight increase in fuel delivery. For most applications, a #5 is recommended.

"Due to the fact that the engine computer looks up and stores this information indefinitely, ANY adjust on the fly fuel controller will do ABSOLUTELY NOTHING! Aside from that, with a range of 4 steps above the std #5 combined with a .5mm change in fuel delivery you can only get a 2mm increase which is quite insignificant"... - JK

This kit allows the use of -10 (5/8") hose from the billet pickup to the lift pump on LB7 Duramax trucks. The OE plastic sending unit head is modified to accept this kit which greatly improves fuel flow. Requires Duramax Billet Pickup for proper installation.
