harder to start
 

hey all, its a gorgeous morning here in ky. i have a small problem. since changing fuel filter my truck sometimes takes a little cranking to start(maybe 3or4).acts like not getting any fuel when it used to start on first bump of key.anybody know what this could be,still runs good.thanks in advance.

Sounds like an air leak. The filter may be loose, or more likely the fuel heater gasket is tired and needs to be replaced.
