Fuel presssure drop

[brickyard69]

I need to determine if it is before or after the pump at this time.

I plan on using a heat spacer on the pump, relocating and covering all my fuel lines in heat wrap, and putting a plate under the carb.

I still think it is before the pump, but no lines are close to a heat soarce. The pump itself seams to get very hot, so I will use the heat spacer.

Any other suggestions?
