What pressure are you using, and exactly what is the meter volume.

I think they mean the literal volume of your meter. Like how many cubic inches it is.

Assuming the atmospheric pressure where you live is 14.5 psi and the volume of your meter is 1.2 cu in. Your pressure should be around 85psi. If you live at a high elevation then reduce the pressure

jmc, you still haven't given the volume of your fuel meter. Measure it and tell us, or you're not going to get anywhere with this question.
