Looking at the new Racor filter assembly, I see it comes with a 200 watt fuel heater. From what I can tell, the heater comes on when the outside temp goes down to around 40 degrees F. Where I live, there are a lot of those days. From my calculations, this adds another 17amps of load onto the alternator. The OEM filter also has a heater. Assuming its also 200 watts, I'd be using a good percentage of the alternator output just for heating fuel. Maybe I'm just old school, but I'd rather not use 30% of the capable output (assuming 105 amp alternator) just to heat fuel. Are those with non-heated additional filters having any problems with fuel gelling? Edited by: Roegs

I haven't had a problem with my "primary" but yet secondary filter system ... We have had some record cold days and mournings here in New England ....


Winter blend fuel and a good additive seems to do the trick ...

Assuming the charging system is the same as gas rigs the amp draw should actually be just under 15. Still a significant amount though!!

I don't think the heater being on is going to hurt anything, My volt meter shows A good charge when truck is running, so I think it's A non issue. I think the heater is A matter of choice.

I just ordered a 690 Racor with heater after reading for about "1 1/2 years?" on additional filters.Most people never seem to have a problem running without heaters, but I believe "bigsky1" did have a problem recently and had a switch to turn on his heater and saved a lot of grief.That was what finally convinced me that you should have one in cold climates.It would only have to happen once"bad batch of fuel" and a person would kick himself for a long time.Now if that did happen you better be able to add one to your filter or you would have to buy a new filtering system.
I don't know about you but if it happened once I would not feel good until I had one installed.Better safe than sorry.If a person didn't want to run it all the time just put a switch on the dash and if in doubt turn it on.


Sent a prime yearling bull to the slaughterhouse 3 weeks ago,had a little too much attitude I thought,cost me big time
Went to get burger from the slaughterhouse man told me that bull was trying to climb over 6 foot stall had to shoot him with the 30/30 couldn't get near him wildest he's seen in a long time.Best burger I ever had



Me and "MURPHY" do a lot of business together and just trying to keep ahead of him

I've got the frame mounted racor filter and have been using 6 oz. of FPPF per 26gal of fuel. And never had a problem until that morning I had to go to town and the temp in the mirror said -32 degrees. An easy 18 miles from anywhere ( no cell service either) my truck started to die and chug. Then finally a brain cell warmed up and fired reminding me I had a heater on the fuel filter and all I had to do was throw the switch. In less than two minutes everything was fine and civilization was looming ahead. I too was worried about the draw from the heater so I put it on a switch. I had almost forgot about it and was wondering with the additive if I ever would need it. Sure was glad it was there. Could not imagine trying to keep the wife warm on a 18 mile walk at -32 degrees. Heater is worth double its weight in gold!!!!!

So Mac I'm assuming based on "winter blend fuel and a good additive" you haven't had any problems. But are both your filters heated?


I don't have secondary filteration and am strongly considering it. But in our Michigan climate, I believe heat is necessary, especially if the secondary filter is outside the engine compartment.

In my opinion if you think you might need a heater, than even if the filter is in the engine compartment"under air box" if used as a first filter it could gell.Remember the first thing to freeze is the filter and it might take awhile to get enough heat under the air box or the lines to keep it from freezing"or unfreeze it".When I was a service tech my motto was "if in doubt throw it out".In this case it would be "if in doubt get it " better safe than sorry
Not everyone would think they need a heater but if you do a couple extra bucks big deal for it only has to strand you "ONCE".Just thinking I remember Racor saying months ago that when their new filter system came out it could have a heater option,well it seems it is not a option but standard I wonder why?

Only my OEM is heated ....


We don't ,here in New England ,see the cold that Bigsky is seeing ... Many mornings below zero single digits only ...I can report my truck will sit for days at these temps and still haven't had any issues ...


I don't think just having a filter IN the engine compartment would solve the problem .... The heater is for startup doesn't run continually as I understand it ...


As Nobull recomends ,if your concerned then get the system that has a heater such as The Racor ...

Mac...as for how long the heater runs, I believe that heater operation is based on outside temp. If its below 40 F, the heater will run continuously.


Bigsky1..I like the idea of a switch. Running the heater all the time just creates a load that I don't feel is necessary. Your point about those rare times is well taken. Did you run it through a relay? Do you happen to have the parts list or a drawing?


Thanks!

I had thought the oem heater was thermostatically controlled by the FUEL's temperature (not outside air) and that the current draw was some function of temperature, i.e. not just a simple on/off thermostat. If true some of the power spent in the first filter would save some power needs in the second filter. I'm absolutely SURE that it was this way in the fuel heater on the '87 diesel 'burb.
In any case, I'd rather drive around with yellow headlights than a waxed up filter

Roegs,


It is run through a relay. I got the whole kit through Greg at lubespecialists. Kit was lacking a good wiring diagram but with help from Greg and some wonderful folks here I got it figured out. 99% of the time just don't need the heater... but that 1%
. I had been driving around in -20's with additive and no heater without a problem. So with some extra FPPF I probably would of been fine but that little extra insurance lets me sleep a little easier.

I was all set to get in on the Nictane GB until I saw this new Racor kit. I make trips up into the interior now and then. Temps can get down in the range of 50 to 70 below. I do believe I want the heater!
