Where do i hook my fuel pressure tester at on this engine. ussually theres a valve like your tire stem on the fuel rail but I cant find it.

Also no matter what I do I cannot get more than 15.6 gallons in my tank. I have a 4x4 extended cab. Could it be my gas gauge is off?

 

wow nobody knows huh, oh well......

 

please tell me your not filling up when the "check gage" light first comes on. with the 4.0 sohc, there is about a 4 gallon reserve in the tank. with mine, my "gas gage" light comes on around when 14.5 gallons have been used, leaving 5 in the tank.

 

I fill up when the light is on. I can't wait when prices drop in the winter!
