Anyone having problems with foam when filling their tank.It is taking forever to get each tank filled, have to wait for the foam to go down then put a little more in. when I fill up the big truck at work I have not noticed this, Is this common, or just something crazy with my truck. Also I have added diesel kleen one time a couple of months ago to both tanks, do I need to do this more often. Thank and merry CHRISTmas

 

its just the nature of diesel fuel... to fully fill my tanks it takes over 10 minutes due to foam and even longer when i use B20 as that stuff really foams as passenger trucks have the tube that help shut the nozzle off whereas big trucks dont so the foam isnt forced up to the nozzle as quik......

 

BIG R,
I rarely have trouble with foam, don't know why?? AND, I use Diesel Kleen with every fill up. I believe it keeps my system clean and helps with power and milage. THEY say some sort of additive is a must since THEY took the sulfur out of the fuel. This is for IP lubrication.

 

1 qt of atf every 5 tanks cheep and the pump and injectors lasted 750 k in my old 2000 power stroke engine ran as good when i sold it as when i bought it

 

what kind of ATF?? mercon?dextron ? type F? with mileage like that im all for using ATF...

 

Just cheep Dextron a old time diesel mechanic turned me on too this says the stuff is almost pure detergent hell all I know it works P.S. I worked the crap out of that truck ! Ever hear of someone shearing off rear spring shackel rivets? I replaced with grade 8's AND welded the damn things back on

 

i had the same problem, i removed the vents and put 3/4 inch vents in the place of the originals. i ran them outside the filler tubes. the problem is not foaming, its venting. of course when it belches on you, you will see foam. my fix was easy, because my truck is a flatbed dump. it would be much harder to re-vent a standard truck. there was a thread on this forum about 2 years ago covering this same subject.

 

PPS truck was a e 350

 

its the vents i have the same problem and its a known problem with fords. i just dont care to try and fix it till after the winter.

as far as the trans fluid . thats the first ive heard of that one. anyone else try this?

 

Thanks for the comments, I knew it was kind of a weird question but I could not understand why it did it on my pickup and not the big truck, now I know.THANKS

 

i know of a diesel mechaninc who runs his PSD ('06 i beleive) on straight used tranny fluid, no probs in over 2 years and he has yet to buy diesel in those years as well... talk about sweet!

 

I pulled the rubber hose out of the fill pipe like was suggest on here, and my foaming/fill problems are gone.

 

Is this easy to do, if so please let me know how and I will try it myself. THANKS

 

Thats next on my project list....

 

The internal vent hose is sorta easy to remove.
Best done when there is less than a full tank of fuel.

Remove the filler cap.
Remove the diesel only plastic label around the fill spout.
Now you should be able to see several screws that mount the fill spout to the body, remove them.
Stuff a rag in the fill spout to keep dirt out.
Next slide under the truck bed.
Now loosen the clamp on the filler hose to fill spout connection.
Slide a small straight bit screwdriver under the hose to break it loose from the fill spout, be careful not to tear the hose.
When you get it loose, remove the fill spout.
The fill spout flange is inside the bed, so to remove it you need to bend the hose and pull the spout under the truck to remove it from the hose.
Again, watch you don't get dirt into the hose.
The vent hose should be clipped to the fill spout.
Pull the vent hose out of the fill hose, file 13 the vent hose.

Now put everything back together like it was.
Go fill the tank, check for leaks.

This does not get rid of all the foam problems, but it does cut down on them.
It also lets more fuel run down the filler hose, so fill time is reduced.
I sill like to use the smaller nozzle pumps when possible though, the big nozzle just flows to much fuel for a fill tube to handle.
Big trucks have a 3" or 4" fill hole right into the fuel tank, no tube involved.
