Fuel system leak!

[VEfreak]

I have a leak somewhere in my fuel heater system. Do i really even need a fuel heater, or can i just throw on an inline fuel water seperator and bypass the fuel heater?

I would recommend it for driving/starting in 5* or below. I don't have one adn mine started at 10* but it didn't like it at all. I would recommend keeping it if it's cold there.

mine starts fine with no gride heater and no fuel heater in -5 temps

To be perfectly clear, I am speaking in "F" not "C". I don't know how your truck even fires at those temps CK. I have seen trucks stall here in below 0* temps driving down the road with no fuel heater. Now they may have been runnin summer fuel, I don't know.

Unless you're driving alot in sub-zero temps I wouldn't keep it. They're more trouble than they're worth, IMHO. For one thing, the fuel passages in there where it connects to the manifold are a flow restriction. And of course those tiny little gaskets are a common problem. All it's going to do is possibly delay a gelled filter if you don't have an anti-gel additive in the fuel when you need it. If that's the case, it's probably just delaying the inevitable anyway.

I ditched the entire stock filter assembly including the heater. Drove it in single-digit temps several times right afterward, no prob.
