on my wifes z with the fuel in the on setting dies from no fuel,if i put it res. it runs fine. any screens that could be clogged ect.. or do i have a vac. break..anybody

How much fuel is in the tank?

Does it run when set to PRI?

[WOWA450RRRR]

yes it runs on prim as well.....plenty of gas

[huffdaddy_400EX]

Since both ON/RES use a vaccum it doesn't sound like that is the issue is RES is working. If PRI works then fuel is feeding correctly (gravity method). I would check the petcock filter. There may be some type of blockage near the top of the filter.

Yeah check the screen for the petcock. ON would be the longer one. You can remove it with the 2 screws on the bottom of the tank. If that checks good pull the petcock apart.
