I'm planning on running dual 40's on my Golf and was wondering...

I plan to use the voltage regulator wire to trigger the relay for the fuel pump as built-in accident safety measure... question is

Do you think that I'll need an additional relay off of the starter solenoid to prime the pump during start, or will the fuel in the bowl be sufficient to get it going? I really don't think it will be necessary, but I'd like to check with you all.

Thanks in advance!
