I was wondering if anyone could tell me why there is a ticking sound coming from the fuel tank on my 97? I can actually feel it in the fuel line on top of the tank but I don't know if its the return line or the feed line.

Has no one had this problem before?

 

I'm having the same problem right now on,98 12v
People have told me its possibly the lift pump

 

Could be lift pump back feeding ... causing pulsing sound ... might wanna check fuel pressure and return flow valve ... problem is shurley simple

 

Id bet money on lift pump my old one ticked real bad noise travels through a truck realy well mine sounded like everything one the truck was tickin i had to use a stethoscope to find what it was

 

It's pressure waves reflecting back from the pump. Rotary injection pumps are the worst at creating that phenomenon. The CP3 will quickly destroy an improperly installed conventional analog fuel pressure gauge because of it.

 

So is it the lift pump or the injection pump?

 

Lift pump

 

Just replaced my overflow valve with a higher fuel pressure valve and the ticking noise disappeared!!

 

less volume more pressure .... wonder how long it will last now ...... mine it ticking a bit but its only when clod

 

Just replace the valve
