Is fuel pump needed?

[nodrog]

I have a Craftsman LT2000 with a 21 HP Briggs. Fuel tank sits higher than carb and there is a pump which I think is bad. Can i just bypass the fuel line around the pump.to the carb?

If the tank is above the carb, then YES... if... while you have the hose disconnected you check for fuel flow by letting a couple of tablespoons of fuel squirt out of the hose.

However, the pump may also serve the disguised purpose of being a automatic fuel cut off. With the tank higher than the carb you MUST have a fuel shutoff of some sort, or BAD things happen.

I highly suggest you simply insert a manual fuel shutoff valve in the line. Possibly in place of the pump. These are available everywhere including Amazon, Lowes, HD, etc, etc for $6-$8.

Hope this helps.

If you were to eliminate the pump i recommend blocking off the end of the vacuum line. Since on some engines it's a path straight into the crankcase.

Thanks guys, I was planning on both if if bypassing the pump was OK. I run old stuff and this is the first "modern" one I've had.
