QUESTIONS:

Hi and thank you for answering my question, Sometimes my gauge when engine off sites at 5psi sometimes seems ok at idle but at woot I see the boost starting to climb too soon and always gives me a reading approx 5psi over of what I should have. Regards

Asked by: Jean-Francois
Hello Jean-Francois, thank you for contacting us. A mechanical pressure gauge should read zero with the engine off and no pressure. We would recommend carefully removing the tubing from the gauge to ensure no pressure is being held. Then also confirm the small little orifice is not plugged with debris and holding pressure within the gauge

I’m just wondering if I need to order a separate  wiring harness for the boost 

Asked by: shedhunter00
Thank you for your inquiry. The 4704 is a mechanical gauge, and comes with appropriate tubing and fittings. The only wiring associated with this gauge will be power for the dial light. The light comes with a short pigtail, the customer is responsible for extending these wires as needed.
