I have the Easy Composites resin infusion starter kit with the VP425 vacuum pump. My vacuum gauge is reading min. -27 even if the hose is clamped. In the video tutorial, it was reading -27 and he said “it should be reading -30... well, nowhere near... there's clearly a leak”. I know there is no leak because it stays -27 for hours.



To narrow down issues, I bought a new vacuum gauge and this one reads -29.



Do you have any such experience? Do you think the vacuum pump is working properly?
