I have a 190 and sprayed 150hp plenty of times, no problems. 155 would be plenty with 75 shot, dont know about the 150 shot.

Yea, you could prob get away with something smaller buy why? For the same price you can go with a bigger pump! It all gets circulated back anyway!

+1 You can't really OVER do a pump, thats what the adjustable pressure regulator is for. Since this is a 'Return' style system.

I am about to buy a 255 pump and regulator... As the fuel pump was the causeof both of my head gaskets blowing up on the spray last weekend...

You can get a 255lph for under $100. Why wouldanyone buy a 155lph or 190lph?
