Re: WATER IN FUEL :-( Reply #25 – December 28, 2017, 09:15:37 pm Does anyone know where a moisture sensor that triggers VMS & Cummins Diagnostic errors, is located? Is the add-on fuel filter sensor wired to engine computer? Quote Selected
Re: WATER IN FUEL :-( Reply #26 – December 29, 2017, 12:11:33 am Today I purchased ISO-HEET and BIOBOR JF. Before the 350 mil trip back home this Saturday should I put in HEET and BIOBOR together or just HEET for the trip and when we get home as usual fill it up and put in BIOBOR for sitting parked for few weeks?Thank you,Al Quote Selected
Re: WATER IN FUEL :-( Reply #27 – December 29, 2017, 01:16:36 am Does anybody know if Heet will migrate to the bottom of the tank in order to actually absorb the moisture, or just float on top of the diesel fuel? Quote Selected
Re: WATER IN FUEL :-( Reply #28 – December 29, 2017, 09:55:54 am PHRED ---- The HEET will chemicaly combine with the fuel and be there until it is used up in the process of eliminating the water. The more water in the tank, the more HEET that will be necessary. I think that it is good to just run some in the tank all of the time if you run alot in humid environments. The humidity in the air condenses in the tank as you burn fuel and air is pulled into the tank. That is the reason for the fuel filters with sediment bowls on them. Some even have drains. All of the old cars I used to have had sediment bowls on the gas line just before the carbuerator. I think that in this age of chemicals that the standard now is chemical treatment in lieu of separation and draining. In any event, just dump it in as you feel needed and have fun driving.

Re: WATER IN FUEL :-( Reply #29 – December 29, 2017, 10:48:19 am You can get a sample from the bottom of the tank using 4' of cheap plastic hose, a metal coat hanger and some zip ties. Straighten the coat hanger and bend it to allow you to reach the bottom of the fuel tank. Zip tie the hose to it so that you can get the end of the hose to the bottom of the tank. Lean the coach so that your fuel fill is the LOWEST point of the tank. Wait at least a half hour for water to run downhill. Suck on the other end of the hose until you see fuel in the hose. Remove hose/coat hanger from tank and pour into glass jar. What do you see? Quote Selected 2 Likes

Ya, another alternative. But, with clear plastic hose, you would really have to WANT to taste fuel to suck it that last couple of feet.A personal choice, but I prefer other forms of refreshment!

Re: WATER IN FUEL :-( Reply #37 – December 30, 2017, 01:16:22 am We use a $10 drill pump to pump fuel from bottom of tank into gallon glass jar, and then let jar sit still for a couple of days. Quote Selected
Re: WATER IN FUEL :-( Reply #38 – December 30, 2017, 06:48:27 am Usually the sensor is in the bottom of the filter assembly in the separator part. Quite often there is a drain there too. Put in the magic chemicals and drain the separator. Quote Selected 1 Likes
Re: WATER IN FUEL :-( Reply #39 – December 30, 2017, 07:27:53 am There was a sensor on my isc at the filter on the engine not the rancor one under the side compartment. Quote Selected 1 Likes
Re: WATER IN FUEL :-( Reply #40 – December 30, 2017, 07:47:18 am This is the sensor wire connection that disconnected and caused our check engine light recently. Simple as inserting and. Seating properly to stop problem. Quote Selected 1 Likes
Re: WATER IN FUEL :-( Reply #41 – December 30, 2017, 09:33:47 am Quote from: floridarandy – December 27, 2017, 10:27:50 pm Exact same thing happened to us during a heavy rain storm. Check the sensor wire coming out of the bottom of the secondary fuel filter which is mounted on the passenger side of the engine. In our case this sensor wire came loose. Re-seated it and check engine light went off. This sensor wire is what reported water in fuel. Remember, this is not the primary fuel filter which is located near the engine start batteries. It is the secondary filter mounted to the engine which has the sensor wire connected to it.I don't see any wires "coming out of the bottom" on our "secondary fuel filter" There are some on the top (I think) but hard to see, there is a bundle of wires pipes and hoses.

Re: WATER IN FUEL :-( Reply #42 – December 30, 2017, 10:43:40 am The water-in-fuel sensor is usually on the primary filter. It works by sensing the change in electrical conductivity of the fuel caused by water. Quote Selected 3 Likes

Re: WATER IN FUEL :-( Reply #45 – December 30, 2017, 09:40:09 pm We just got home without any issues. I ended up putting only 4 containers of ISO HEET. 4 is good for 80 gal. I had about ~130 gal of diesel. I did not change fuel filters, they are 7K mil new and there was no water in the sample I had drained from the primary fuel filter. I have no clue where and how "water in fuel" alarm and diag came from for about 40-50 mil. Perhaps it was the sensor. Quote Selected
Re: WATER IN FUEL :-( Reply #46 – January 01, 2018, 05:38:44 pm Quote from: Don & Tys (AKA acousticart) – December 28, 2017, 12:53:51 amIf you don't find a threaded collar on the bottom of the replacement filter, you may have the Baldwin BF1329 which doesn't use the clear bowl. The Baldwin BF1329 has a valve to open on the bottom of it for draining the filter and it can replace the Racor just fine. I used the Baldwin BF1329 through a couple of filter change cycles. Not having to deal with the separate clear bowl is convenient, especially if you will have to change the primary filter several times in short intervals to deal with a load of bad fuel. The only difference is that you don't have the clear bowl .................DonDon, et al,While subject is fresh. Please see attached pictures. I am puzzled with primary fuel filter. Part number on the current filter and the one I purchased are same but one has the clear bowl and the other (new one) don't have it. I somehow thought there is a way to remove and attach the clear bowl to new filter.Link to pictures of primary fuel filter on google pictures.So what do you do, punch a hole to the under side of the new filter where the clear bowl will screw on?
