If I swapped in an intank 255 pump, would I automatically be able to start spraying a 150 wet shot? I'm spraying 100 right now, no problems, and would just like to be safe for the 150...

Would I need to do anything else? I figure a FP guage off the rail might be a good idea too.

thanks

 

Best thing to do would be to run a "remote" fuel pressure gauge, and monitor the pressure while on a dyno. Start off with the 100 and make sure it doesn't drop off before giving it the 150.
