I was driving home from work yesterday and went to pass a car when i stepped on it the engine started surging really bad like it was running out of fuel. I got home and turned the smarty back to stok its alot better now but if im crusing down the highway i cant get anything over 2100 rpm. I just replaced the fuel filter about 4000 miles ago so im guessing thats not it but im going to drop a new one in it today just to see. truck has 102,000 miles on it and as far as i know it still the original lift pump. im guessing its the lift pump, any other ideas would be great before i spend the money on a new pump

thanks

dont know. do u have a lift pump gauge?whats ur rail and lift pump pressures?

 

the only gauges i have are boost egt and trans temp. i dont have anything to moniter fuel pressure at the pump or the rail

 

could be faulty fca regulator

 

were is the fca regulator located at? any way to tell if it is bad?

 

i tried a new filter in it this morning and before i tried starting it i turned the key a few times and rolled the engine over to fill the canister. when i started it, it ran for a few seconds then shut off like it ran out of fuel. i did notice when i first turnede the key i could not hear the pump running like i used to, insterad it was just a clicking sound. after this im guessing its the pump. thinking about putting an air dog on it should i go with the 100 or 150 and how hard are they to put in?

 

Go with the Airdog 100. Plenty of fuel and easy to install. No need to install a draw straw.

 

depends if its not got the update.......

 

Where does everyone install these airdog's?
