So something was going wrong with my walbro 255... It kept running out of fuel up top but not really as in the pump wasnt keeping up but more of the pump was broken, or hose was leaking.... To be on the safe side i got a new ppump.. walbro 400... Put it in everything looked fine... put the tank back on and then guess what... No start..

You can hear the pump running but im not getting any fuel to the fuel rail...

Soooo any off the wall reason for this... The last two pumps i just dropped in then was back on the road..


Also whats the deal with the new pump... Im not the smartest guy but the hole in the bottom of the pump on the new 400 thats suppse to support 800 hp is the size of a plasic pencel that you click and the led comes out where as the old 255 pump is the size of a sharpie... So how does a little hole flow more than huge hole?
