I need to get a secondary diesel heater before this winter. While the block heater takes care of the front end I have gelled up at the rear fuel filter even when adding the higher amount of anti gel when I am going to be in single digit or below zero temps overnight. What suggestions does anyone have for a rear filter/fuel heater that can plug in to a 120v outlet like my primary block heater does? I have a fully stock truck, no different fuel delivery system, extra filters, or extra tanks.

Thanks in advance.

 

You should have no trouble using an anti gel in that temp range.
Maybe try a different brand, also over dosing only makes it worse.

 

Odd that you have fuel problems. Where abouts do you live? Here in Michigan, we get regular winter lows in the same range, and whatever the fuel suppliers add is sufficient. Just wondering if you travel between warm/cold climates a lot, and have warm climate fuel further north than you should?

 

I run into the issue in northern NH. It happens a few times a year. I will try some other anti gel (I'm told Howes is good but never tried it) but I am looking to avoid the issue as much as possible so I'm looking for recommendations on secondary fuel filter heaters.

 

Had that issue in New Jersey. In the middle of the woods during a camping trip. It was -6°F that night. Getting it going required some work that morning.

 

Don't feel bad Upstate New York last winter we had two solid weeks 3 degrees during the day and 18 and 20 below standing ambient temperature not wind chill unbelievable the only thing I found that worked was the Howe's fuel additive nothing else even helped a truck driver told me it's okay to double it up when it's below zero and according to the website you can never overdo it don't know how much faith I have in that but I can certainly tell you I went over there recommendations and every 18 below morning the truck started with no fuel gelling take care

 

Never heard of anyone needing this. My truck sat for a week in -37c or -35f ish last winter in northern Manitoba. Plugged it in overnight when I finally needed it. Fired up no problem, this 6.7 is awesome. It had the recommended dose of Ford's anti gel in the tank thou. We might have better winter fuel possibly. Once the truck starts it basically has a fuel heater already, not sure if it's on the primary or secondary system thou, but plugging in the block heater should help warm the coolant faster.

 

 

Adding too much anti-gel often times can be far worse than no anti-gel at all. Too much anti-gel clumps up and plugs the fuel filter, causing the truck to run as if the fuel is still gelled up.

Never use more than the maximum dosage listed on the bottle. You'll get no additional benefits by adding more, and could actually cause more problems if you overdo it.

 

I gelled up one time at -37F and that was my own fault for not adding enough anti-gel. What I do now (probably overkill) is run 25% #1 diesel / 75% #2 diesel mix plus I add Howes. When I can't get #1, I just run Howes. Haven't had a problem .

As for filters, I order Motorcraft filters from Amazon . I also have a spare filter bowl on hand just in case.
