QUESTIONS:

How can I interface the braided hose kit from the vacuum gauge to the vacuum port on my Proform 850 race carburetor?

Asked by: Rob75

Thank you for your question. The braided kit comes with the fittings needed to adapt to an 1/8” NPT port which is common on that type of application.

Is there a max length of hose to maintain accuracy?

Asked by: Chief sparkey

Thank you for your inquiry. Hose lengths up to 20 feet for rear engine vehicles are typically no issue as far as accuracy.
