I changed my front and rear fuel filters today. Have done it many times. But today when I primed the fuel and started it, it died after maybe 5 seconds and will not start. Checked rear all tight , no leaks, checked front no leaks. Took of front cap, no fuel in canisiter. Took out filter looks fine . Put back. Went to rear to see if it was getting fuel. Turned drain, fuel came out. Tried to prime again. Still no start. Checked for fuel,.still none in front canister. Did I get a bad filter? I need to truck to move my 5th wheel . Please help.
