so, installed my guage between fpr and fuel pressue guage, right after 255 lph walbro fuel pump install. tested for and fixed a few leaks i found. tested a second time and had no leaks, but no jump, spike, flinch, nothing from the guage needle after multiple tries with key turn. took off the return line and fuel sprayed everywhere. do those guages need constant pressure for reading, warm up, or a specific orientation(vertical, horizontal, etc) to function properly? thanks
