installed the raptor 150 yesterday and the truck started fine and had 30 psi + of fuel pressure, it ran for about to mins and then died, could get it started for a few seconds then died again, i called tech suport and the guy told me that it was more then likley the lift pump in the tank, i looked on my motor and did not see a lift pump, so he told me to order a draw straw kit and it should fix it. when i took the filter cap off and ran the pump, it would spit a lil bit of fuel then air, i bleed all the lines, will the draw straw fix it or could there be any other problems, need help asap!!!!! thanks

TOO MUCH PRESSURE!

10 PSI MINIMUM PRESSURE AT WOT
20 PSI MAXIMUM PRESSURE AT IDLE

You might of blown the VP44... Stock pressure they typicall are around 14-15 PSI because of the overflow valve...
