Terry, The Aquamist pump with two large accumulators would support your truck for a 30sec full throttle run. The pump volume is too low for the amount your truck will be able to use with out the accumulators.
I can e-mail you a picture of the accumulators if you like.

E-mail info to Captez01@aol.com. Also any diagrahm on modifying the system would greatly be appreciated. Thanks, Terry
