Fuel line system setup replaced with OEM parts, new pulse pump replaced.

Still experiencing the same symptoms.

The guy that had the pulse pump told me to check the shrader valve on the air side while experiencing the issue. If gas comes out, it's most likely the air/fuel diaphragm.

I checked that, and had raw fuel come out of the air side. I pulled the diaphragm out and it is indeed cracked. I found one locally (expensive little things). On my way back to install new fuel/air diaphragm.
