ZL1 Fuel Module Specifics

[cwoolf]

I’m trying to integrate GMPP’s ZL1 Camaro fuel pump into a custom car project, but I’m missing some of the critical numbers and was wondering if anyone knew them, or knew where to get them:

1. What is the pwm frequency required for the pump (13kHz?)
2. What pin does what (power, ground, float level, and ??)
3. What pressure is the relief valve set to? (88psi?)
4. What’s the current draw at max (20A circuit enough, or is that overkill?)

This seems like a nice fit for my project but super hard to pin down for specs. The pump just arrived in a box with some seals an no spec sheet or instructions, and I can’t find a GMPP tech line to call so I’m getting desperate.

Thanks all.
