[88ecdiesel]

i have a 1988 chevy silverado that will not keep running under -25 cel conditions. service fuel filter light comes on and truck losses power. truck will eventually stop but will start again when i pump it! the fuel filter only has 700 miles on it. how much anti gel can i add without damaging the motor? do i have a second filter that i'm not aware of? send answer to clm_mathison@hotmail.com thank you.....doug

Hi Doug,

Welcome to the forums.

If it's cold outside the possibility of gelling fuel is more likely, although I've not witnessed it here in Texas. But...

The symptoms you're describing sound like gelling fuel.

Add the recommended amout of additive to the tank for the amout of fuel you have, I don't believe you'll hurt anything by running it stronger than specified (within reason).

It's also possible that you're not getting fuel pressure to the fuel filter due to a failed fuel pump. Your truck being an '88 (new or old body style?) could be equipped with an electric fuel pump driven by an Oil Pressure Switch. If either of those components has failed you'll have a fuel delivery issue to the ip and through the fuel filter.
