Leaking fuel pooling @ front - source located & repaired.

I tried to find my original post on this. Anyway, the problem was that the vent tubing from the diesel tank was not fuel rated hose. It disintegrated in several places causing fuel to leak from several locations when the tank was filled full. The hose was replaced and the front cap was steam cleaned. Big thanks to Steve Scott at Cummins Coach Care in Coburg for squeezing us in and finding the problem so quickly.

Slow fueling on Coach?

Has anyone had to take 30 to 45 minutes to fuel their rig?

34 FDDS #74867 ISL 400

Thanks for any help.

You can improve the fueling rate by a making sure the vent hose from the tank runs on top of the filler tube. I sometimes set the front jacks to lift the front end. Lastly and I don't understand why, but when we fuel at the truck islands, the fuel fills at the fastest rate. In and out in minutes compared to the RV islands.

Hi

Check to make sure the fill hose is not sagging. If it is then the fuel pump will think you are full and shut off. I had this on a Monaco coach.

The reason the fill up is faster at the truck pumps over the regular islands is that the truck pumps are high speed pumps with larger nozzles.

As Tom and Patty said, use the truck lanes not the RV Island. If it takes that long at a truck pump then you probably have a vent hose that is not venting.

I can probably pump 50-70 gallons in about 5 minutes at the truck island of a truck stop. Probably twice that if I have to use a standard nozzle at a gas station. So far I have never had a problem with it taking a long time or shutting off early.

With a mid-door, I can fill from either side. Normally I use the driver side filler. Theoretically I could use both fillers at once, but never tried. No need to with the speed of the truck island nozzles! I am not in that much of a hurry.

Jim,
I have heard that having the cap off on the other side is a disaster - it's not intended to fill from both sides at once. If you look at the hose routing they both go into a single port on the tank, and supposedly fuel will go out the other filler as likely as into the tank.
No personal experience but thought a word of caution was appropriate.

I just recently filled my tank from both sides with excellent results. It was unintended as I had pulled into a truck/RV filling station that had nozzles on both sides. In my confusion (seems to happen a lot lately!) I had inserted the nozzle from the secondary pump into the right side filler only to finally have the attendant come out and show me that I needed to use the pump on the left side to get things started. Since I already had one nozzle inserted into the right side, he asked me if I wanted to fill from both sides to which I replied, "Sure." It worked great and filled the tank in record time. I have replaced the vent hoses and have them routed on top of the fill tubes so apparently don't have an issue with venting. Anyway, from my recent experience, it apparently is possible to fill from both sides with no negative results.

Filling from both sides works just fine--though I agree, filling at the truck islands is pretty fast so you really dont need to do it. With over 13 years of travel and approaching a 150K on our 03 mid-door, we have never had any of the "fill problems" experienced by other folks [belching or leaking]. I do make it a habit of "cracking" the pass side fuel cap to improve venting during a fill but cant tell you that it helps any.
PS--if you use both sides, remember to tighten both caps----duh....

When I had my 2000 36',built in Oct 99, I had a slow fueling problem for 10 years. You fill it up 3/4 of the way real fast. The last 25 gallons took 20+ minutes to fill it. I took it WRV several times, who rerouted the vent hose and nothing helped. When I filled fast and quick, it was not full and the gauge showed full, but it was not accurate. The problem was that fill pipe was not near the top of the tank, it was like 1/3 of the way down form the top. You were trying to push the last 25 gallon of diesel into the tank. Just a poor design. If you have a slow fill, I would look where your fill pipe enter the tank.

I have lowered the fuel tank in the early model Alpine's and it has helped a lot.

Geoff,
If I try to fill at the RV island the pump is constantly shutting off, despite the lower flow rate. Especially as I near the last 10 gallons or so. But pull into the truck island, pump the fuel at a high rate, and I can fill right to the top.

I observed at the Flying J in Rocker MT that the price on the smaller nozzle at the truck/RV island was 0.04 cheaper than the large truck fill nozzle. That was several months ago so it may have changed.

Could it be that the foamer that makes the shutoff work is creating more foam with the RV nozzle than with the truck fill nozzle?
