fuel filter or pump?

[bhyche]

2008 X2 - had been running fine all weekend. Late Sunday PM ... idle fine ...but soon as you would give any throttle - would back fire and stall or shut completely off.
Continues to idle fine - just no throttle?
Filter or fuel pump? How hard to change?
Tank was full to start day - got down to about 1/2 tank.
Have been adding stabil during last few fill ups to get in system for winter storage.
Thanks.

Others will chime in, but you should fill the tank then pressure test with a gauge. I don't think fuel passes through the filter with a full tank.

If the pump test bad, change the filter too. The filter should be changed every 2 years anyway.

I think the fuel always goes through the filter. If it didn't it would be pointless to have one.

I had those exact symptoms earlier this year and it was a bad fuel pump. Probably they are symptoms of low fuel pressure which could be caused by any number of things including a clogged filter. However given the history of these boats my money is on the pump.

Putting a pressure guage on it is a quick and easy way to confirm you have a fuel issue.
