Hrm looks like I have a heated fuel line? **PIKATURES!!!

Ok, I admit I haven't spent as much time under my hood as I should - but I have an excuse this is my project vehicle - working on my compressor I noticed a strange golden pipe wrapped around my fuel filter housing's intake line. It has a wire going from it to another connector. Sure looks like a fuel line heater to me! Pictures attached for your viewing pleasure. Diagnosis?

Also, wondering what the schrader style valve is on the fuel filter mount?

Can't speak for the heater, but the schrader valve is to bleed air out of the filter...

what you're looking at is a fuel line heater for the 6.9 motored trucks. the 7.3 trucks have the heater built into the filter head.

Interesting, so they ARE heated. Hrm. So any idea what temperature this will heat the fuel to?

Interesting! I just looked at my spare engine since my tow truck isn't here and saw the same heater. Is the efficiency of this heater known? Maybe this heater can be used in conjunction with a heated 7.3 filter head to heat wmo better? I'm also figuring using an insulater such as rubber hose to keep the tubes warmer.

Lol! warped minds think alike

guys-
it's only designed for initial start-up use. Not a constant-duty item.

where is a good place to get a constant duty inline fuel heater electric would be nice i can get the coolant type
anyway my truck has a hell of a time starting on 100% WMO i just flip my switch for my diesel tank at night let it idle down and in the morning fires right up fine

the copper line is used for intitial startup only in 30 degree or below weather to reduce hard starting

Since the in-line fuel heater gets power whenever the key is on it is constant duty as long as you keep the internal switch on the heater below 34 degrees. Around zero mine heats all the time and usually the one in my Racor does too, as I often forget to turn it off in the summer.
That reminds me...

Personally I "salivate" over things like this...my boat and what's sitting on it

Hrm interesting, I would have a completely different physiological response (than salivating) to the woman on the bow of your boat - the boat - well, doesn't do much for me...

 

[Joe Mc]

mankypro,
Those are both nice, but they are what I ran on my big trucks, I use the Racor 645, it is cheaper and easier to install on your truck.

HammerDown, I started to say that she would look better on my boat; but then I saw the last line on your signature.... Maybe she does look better on your boat.

Dang Ray, you shouldn't post pictures of your daughter like that!

Is the 7.3 filter heater constant duty? I always thought both types were. I didn't know the inline one had an intergal thermal switch.
