I was laying under my truck while it was running today and I noticed a clicking/ticking. After a little nosing around, I noticed it was coming from the fuel sending unit on the top of the tank. Is this normal, or something to worry about? No leaks or anything out of the ordinary except for the clicking coming from the unit.

Thanks,
Shawn

Mine does the same thing, but I hadn't pin pointed the source of the clicking. My fuel gauge is all over the place... is yours?

Mine's pretty consistent. I guess you could call it a problem if after 240 miles it's at half tank, but I can't pass the blame to the fuel sending unit for that

I noticed that same sound after changing the sender. It seemed to me that it was the return line pulsating as the fuel passes through, not sure if that's what it is though.

Mine did the same thing. It has stopped after i changed the fuel module and the fuel lines to rubber hose. I dont know if that has anything to do with it. My two cents worth is maybe it's the steel fuel lines transmitting the pulses from the IP.

pulse from overflow valve dumping back to tank.

Normal or no?

TIMMY22

yea, if it's the extra fuel comming back through your return line it's totally normal. the sound is spurts of fuel chattering through the overflow valve. try a few cable ties around the return line in that area.

It's the same pulsation that kills fuel pressure gauges if they aren't dampened. Totally normal.

Works for me. Just wanted to double check about that odd sound.

Thanks yet again guys,
