Testing some fuel coolers.

Read a driver post a question about fuel coolers and MPG, so I had some installed. 1 before the pump that feeds the feeder tank, one just before each injector and 4 along the return line. Noticed an increase in my MPG. I''m getting 8.6-9.2. They really help running out west in the heat, the Maxxforce and newer 9400i's are known to put the diesel under A LOT of pressure and high heat, this is due the the inner engine reaching high temps. So, the coolers did help my MPG and I got slightly more pull out of the engine. Took the dealer a day and a half to put them on, an extra 4 hours to put the engine back together.

 

Not sure, International just threw whatever they had on. Nothing fancy because it didn't cost to much.

 

Ah, trying to get something on it but nothing yet. What I can think of is a wireless temp thingy and drop that in the tank, but then you run the risk of it getting pulled in by the intake pumps.

 

Perhaps, not so sure about the third generation truck engins.

Yup, why I put 4 along it. My pumps need to last as long as possible, pricey if one goes bad. be my luck one heats up and catches fire!

 

I paid about $200, I can understand that because it was only 1 guy working on it.
