Fuel on Ground after Fill up?

sbohner · **Posted:** Fri Jan 05, 2007 7:55 am

After I fill my CRD up, 2 out of 3 times, there is what appears to be overflow coming out of the back of my tank :roll:

. I do not put more fuel in after the pump automatically finishes and this happens in all seasons. Do any other CRD owners have this problem and what have you done about it? Thanks for any direction you can offer.

Yes, this is common.
If you get underneath your CRD and look above the fuel tank on the drivers side, you will see a white plastic overflow tube hanging off the top of the tank. If you fill your CRD tank by overfueling all the way up the neck to the fuel cap, drops of diesel fuel will come out of this tube and onto the ground.

The jeep is just marking its territory...this is normal

I regularly fill up to the neck and I've never seen any fuel puddles.

Maybe your CRD has prostate trouble? I suggest a good dose of FLOWMAX :lol:

Then again maybe mine needs DEPENDS!

Thanks guys... Whew, I was worried that my incontinent CRD was headed to the operating table (again). I'm in a region with only one other CRD and the dealership's CRD intern surgeon is too eager for experience :wink:

. I was thinking that with only 10K miles, it was a bit early for the CRD to soil itself -- that's my job as the driver when the CRD asserts itself in some suburban jungles like Washington DC, Philidelphia, and Boston.

I guess to avoid the Dr. TooEager, I will go with the "marking territory" assumption :lol:

. Again, thanks.

Yes, there is an overflow tube on the fuel filler. If you try to "crowd" the tank very much, fuel will overflow on the ground from the overflow tube. The bad thing is that it may take a few seconds for the fuel to actually start dripping on the ground, so you can spill a fair amount before you notice it. Obviously, it's a waste of darned expensive fuel, and fuel stations (along with the environmental agencies) take a dim view of spilled fuel. Diesel fuel is especially bad because it does not readily evaporate like gasoline and tends to soak into the ground.

So, I quit trying to "crowd" the tank very much after the initial fuel nozzle shutoff.

HMmm...i always use diesel in my pump sprayer as a weed killer...do it once a month around the fences and such...works great and is cheaper than round up. How do they feel about that?

This happens to me all the time so what I try to do is slow the rate of fill after about 16 gallons. This cuts the foaming down and seems to lessen the spillage. :roll:

Same here no leaks ever.

Our CRD was able to be filled completely full at the start. Then one day the dealer drained off a tank of fuel for what they mistakenly thought was bad fuel. anyway, after that fiasco, when the vehicle was being filled, it would without warning dump fuel onto the ground from that overflow vent PRIOR to the pump cutting out - not cool. Took it back to the dealer and they put another filler tube on under warranty. Back to normal now. My two cents'worth.

I noticed mine doing that a few times, but started filling it slower to cut back on foaming and I have not had a problem since.

Tried to fill too full today with the fine 50 cetane ULSD fuel and not only did it PP on the ground from he overflow tube, but I even managed to get it to flow out the top at and over the side onto the paint. Hey I admit I have done it before, too many years of fueling VW's and venting them for an extra 2 or 3 gallons I guess. By the way it was $2.48 for the fuel today and I bought 28 gallons, 12 gal in jerry cans.

I heard diesel is biodegradable. One of the problems with long term storage of diesel is all kinds of stuff will start growing in it. There's a thread around here with a picture of horribly degraded fuel that appears to be chock full of algae.

Now, gasoline spills that soak into the ground (or leaking underground fuel tanks) are a big problem. There's all kinds of nasty chemicals in gasoline.

You are almost half right!!!

What causes the things to grow in diesel fuel is pariffin, it also causes the fuel to jell in the winter.

When you use #1 diesel you can store for years in colder climates like the US did durring WWII, but even #1 D has enough pariffin in it to have some growth if conditions are right.

The new ULSD has VERY LITTLE paraffin, about like #1 diesel and was the cause of the big worry about being hard on fuel pumps & injectors if they didn't add some type of lubrication additive, such as a small amount of bio-diesel or some other type of lube additive.
