My pressure guage always reads 0 unless u run over 2000 RPM. I just bought this new one from TFtestkit site. I was so excited to get it. I didn’t pay attention to the fact that it is a rear mount. My current guage mounts vertically so the stem is under the fiat he not behind it. Can I use this? It will be a nuisance as I would have to walk over to the equipment and look down to see it rather that look across the pool.
