I think I have jelled fuel in my system, 1993 F-350, If I now put in anti gel and heat my truck with a torpedo heater,( I can not get it in my garage) will this un gel the fuel? If so what elese should I do, if not what do I need to do?
Thank you,
David

 

That will do it....but it takes some time. Put your anti-gel in the filter bowl and the tanks.

The torpedo heater will be a lot more effective if you can figure out how to keep the heat in. Using cardboard as an underpinning works ok.....or a big tarp.

 

block the air somehow especially on the side the fuel lines run down the frame and take the fuel filter off and replace it (or take it inside to un gel). fill the filter with fuel and a little bit of anti gel (power serv) is what we use in all of our tractors usually start to put it in in mid september. or even kerosine works good my dad puts in about 5 gallons between the 2 tanks

 

Get some diesel 911 from a truck stop, auto supplier, diesel fuel station. Add to fuel and filter. Let the truck idle for 15 minutes before trying to go anywhere. DON'T get fuel from a low volume dealer. If possible get a premium fuel. My 93 has not had a fuel problem but I run the best fuel I can get. For a few cents difference it saves a lot of headaches. I see your from Michigan also and in the Lansing area tonight it is going to be 5 degrees. Where I work - yesterday we had 2 buses gell up but the boss insists that #2 is fine. He doesn't have to go get them......

 

As said, use premium fuel if possible. Desiel 911 will work great, but you have to replace the filter. Heat her up and you should be fine. If you do use #2 (which should still be blended this time of year up where you are) always us Power Service with every filling, it is cheap insurances. I buy it in the gallon jugs and then just refill an old quart container that I carry in the back of the truck. This far north you have to stay on top of your fuel condition.

I'd like to expand on this discussion with my first post/reply. My brother has a 1999 F450 and has station blended fuel, with recommended amount of Power Service, also plugged in at night + new filter. Truck starts fine, goes a few blocks then stalls. It is obvious that there is a line exposed to cold air that is not effected by his efforts. I have had the same problem in the past with another model. Has anyone had success with specific heaters that work?

 

1-2% unleaded gas is what i used in my semi's worked better & cheaper than anything else just remember a little is good a lot is not & none in the filter change it.

""" think I have jelled fuel in my system, 1993 F-350, """

OK so you think you do, what is the temperature in your area if above 32*F then the fuel heater will not be coming on. Why don't you use the engine block heater to heat the overall area. You do not say what area your in or local temps.....

You could do a Pressure and flow test at the Schrader valve on the Filter header to see what pressure and flow you do have.........

Do pressure and flow test of the fuel pump at the Schrader valve on the filter (FSS- fuel shutoff solenoid disconnected). Remove the tire valve core and hook a hose and pressure guage on it should see 4-6 psi when cranking. Then do a fuel quantity test same place, should see 1/3 pint in 10 seconds of engine cranking, route fuel to a suitable container with a hose.

If there is a problem with the lift pump and you are changing it, ensure the new pump comes with instructions as to correct installation procedure if it is the newer model pump with the almost straight arm.

I have used Hayes Diesel Treat which most OTR truckers use and is added to fuel in the winter at many truck stops. I have used Diesel 911 BUT read the small print, there are some conditions that require an additive from their other product line to work in all situations.

Most important when was the filter last changed and how long ago did you drain the water from the filter.

 

Lucky dreamer - sounds like he has moisture freezing up when moving . The heat from block heater is thawing out the water (maybe in fuel filter)while sitting still in driveway. Then when he gets moving it freezes up - restricting fuel flow.

 

I agree with you Big Red. Resolving the problem may be as simple as getting the moisture out. However, He buys from a high volume truck stop and has additives added each tank. He replaced the filter and the very next morning the Jelling returned. Using the block heater is a recent experience. He did not start using it until the problem started. I once had a 85 F250 that had the same problem. I always thought it had an area where the line was exposed to direct wind. I owned the truck 10 years and never isolated the problem. Finding where the spot thats giving him problems may come from others with the same model that have identified a problem area. It's still early in the season and with temps that fall below 0F on a regular basis not finding it may become a safety issue. Power Service is readily available here. I Have not heard of Diesel 911 or Hayes Diesel treat mentioned by PLC7.3. Is it another Brand of approx. same product as Power Service?

 

Stanadyne, Power Service, 911 and Hyes are all similar in design as additives but they all work a little different.....cost too. Stanadyne Pro or Lubricity is recommended by Ford after all the IPs are a Stanadyne product.

 

ONce you get a dose of water in the tank , its hard to get it out. without fail, it will show up in the coldest of mornings after you have left the warmth of the garage or house and nobody else is letting you in to warm up.

 

I used to use a gallon of gas in each side in my big truck but now the computer will pick it up and shut the engine down.

 

I know many a driver has used that method. Just can't convince myself thats the best way.
