98 150 hp runs fine at idle and get 5000rpm but if i let it idle she will run out of gas and i have to fill up all the carbs by pumping the primer ball. or if i put her in gear and take off she'll do the same thing but alot sooner.

Either the fuel pump isn't functioning, or the supply is blocked. You can pump it up so that should eliminate the blocked supply theory. Snif around for a line leak. It could be sucking air instead of gas. Gas would also leak out. Your nose will know. Light gassy smells aren't unusual. But if it's strong...<br /><br />The fuel pump can fail to function either by a problem in the pump, or the driving mechanism. That would be crankcase pulsations. Low compression would weaken those pulses. Hopefully that's a longshot. More likely would be the primer bulb. The valves are crude and fuels tend to warp some. That can sometimes leave a primer bulb that seems to pump well, but blocks the fuel once the motor is running.

Try rebuilding the fuel pump you now have on the engine. I would also replace the bulb.

Did you use the same bulb on the remote tank and your main tank?<br />If so are you sure the bulb is ok?<br />Also check that its connected at the right direction.
