FICM Relocation

[dmaxvaz]

i say don't run fuel through it, if you don't have to.

Find something else to cool it with.

Anyone have an idea what temp the fuel is when going through the ficm? Let's say it's a pretty hot day, your running at about a 1/4 of a tank, and your hauling a pretty heavy load.

Just something to think about.

its cooler than using engine coolant

I think he is refering to using a pump and tank of something else like coolant or water/meth to keepfrom using something hot. Like a closed loop system.

I wonder since the FICM is over there already if you could use the windshield washer pump to run the fluid. I just wonder how long the motor would last.

I know, Im going though the same stuff And I want the ficm in the cab
How about you cool it with washer fluid, a small fish tank pump and your in da business

Not enough volume. You would never be able to cool it fast enough.

Anyone who is running water/air intercooling would have an ideal supply of water to cool the FICM though. Or even coolant would be better.

What sort of temps have you seen for fuel? I bet with a 1/4 tank and towing in the summer, it gets hotter than coolant. Unless you use a big cooler and a fan on it.

Winter time and cruising it may not be that bad.

Inside of the cooling tube is approx 3/8" in a stock set up the gear pump on the cp3 is the only thing flowing

A small fishtank pump can pump up to 500 gph and with a small seperate tank there would only be hydrostatic pressure to deal with.


What am I missing?

Yes i agree with this. But we really need to see more data! Todd does a lot of research in this dept

Your missing the large volume tank.

I disagree

 

[sweetdiesel]

Your missing the large volume tank.

You dont know how big of a tank untill you actually see the temps?
Remember that we now only have 1 thing to cool now... there are a lot of reasons other than the FICM that increase the fuel temp....Right?

 

[bullfrogjohnson]

Your missing the large volume tank.

What kind of volume would you need? I would think the windshield washer tank would be plenty big unless you think whatever fluid you used would foam up when used in a looped system?

 

[dmaxvaz]

I disagree

SAME HERE, IT WOULD MELT THE TANK ANYWAY I READ SOMEWHERE THAT IT GETS TO LIKE 110*F

You just read the opposite here? How do you know what is accurate?

 

[LBZ]

Well I suppose if it was the FICM only, and it was relocated off of the engine, 2 gal may be enough. Still needs a cooler though IMO.

I was thinking about the heat of the entire fuel system before, not running the FICM in it's own circuit. My Bad.

Where's Larry Jewell? He logs everything that has something to do with temperature. I bet he has some fuel tanks in a couple logs.

I have personally logged Higher temps with the fuel than my ECT....But that doesnt matter, If we are taking it out of the loop.

Now say you are correct Dale and the heat from the FICM cannot be cooled enough with a small tank. This would actually be good news! Because we are now cooling the rest of the fuel system via removing the FICM heat out of the loop.

However, I dont know personally how much heat is created from the FICM....I just know how to find out.

i think adding a cooler with a fan mounted on the front somewhere filled with coolant with a reservior wouuld be good. then maybe get a temp gauge to monitor the temps.

some one could have a temp gauge to see hoe how the fuel comes out of the FICM before removing it from the fuel supply system. and see how it would compare to a different smaller cooling system for the ficm

 

[2500HeavyDuty]

an easy way could be maybe finding another fuel temp sensor and making a longer harness to add a second fuel temp sensor right after the FICM and then you can log it with out adding a gauge and have the the data saved on the computer

This is what i know to this point, i have done some of this.

Return at the rail is hot enough to make you think you burned your finger, Reconsider rubber hose (good to 200) remove a section of hardline return and tap in a 1/2 soft line run the temp guage off of it.

FICM can see/mine has seen more than 14 PSI, my water to air system, cooling my FICM/Fuel/IC Exchanger, sees way over 18 lbs of water pressure. 1000 miles later NO issue, no leak, no related codes. 4 hours of run time and after a hard pass, i can stick my finger in it, its warm not hot.

Drove it 4 hours today up to Orange County and back, daily driving every day.

Thanks Simon. Water to the FICM was his idea.

How many wires theres going to FICM?

 

[TNRGreene]

Anybody ever take one apart to see if it "needs" to be liquid cooled or could we put a heat sink on it & cool it with air? Maybe like a computer processor?

going to look at spare now

 

[TNRGreene]

The fuel can not cool this that much the way the lower plate is made. After seeing this inside I'm gonna redo the bottom plate & install a computer fan & have it move air through the entire assembly. I'll institute a cold air intake to isolate it from the under hood air.
