ALLEVIATING DIESEL PUMP BURP?

[Page Britt]

We also fill in the truck lanes where sometimes you can find the older spec. low sulfur (real) diesel fuel as opposed to the BTU diminished ULSD fuel being forced on us by the government. Speaking of which Pilot has a listing athttp://www.pilottravelcenters.com/Locati...elType=All which shows which Travel Centers gave LSD as well as ULSD and the current price. Enjoy it while it lasts.

What I do is fill at the slowest (most restrictive) click on the nozzle handle catch until I guess I'm about 30-40 gals. from full. Then I take a flashlight and sight down the filler over the nozzle looking for foam while I MANUALLY operate the nozzle at a conservative rate of flow pausing occasionally to let it vent. Most of the entrapped air will be dissipated by the time ours is close to full. Then it's a matter of very slow flow and more frequent pauses whenever the foam starts to significantly rise in the filler to top off. Note - LED flashlights particularly those with a visibly blue color like the LED Mini Maglite will cause the green dye in on-road diesel to fluoresce. The effect is very evident at night but a considerable aid in seeing liquid fuel and foam down the filler even in daylight as it's kinda dark down that pipe anyway! Only received one diesel bath before I got the hang of it, but I do tend stand with my body back behind the filler door just in case. Some high flow truck lane pump / nozzle combinations are more conducive to slow manual flow rates than others but this technique sees to be generally work with most all of them that we've encountered.

Granted if John's invention will work as well on a PT as it does on his FC it would be easier.

John,

I have the insert that drops into the fill spout and the one I have still burps. I would be interested in seeing a pic of this to see if it's the same thing I have. Could you post a pic?

I think it is about 12", I cut a 18" piece of 1.75" top rail pipe, drilled 4 holes about 2.5" apart in a stright line from the tank side on my inserted pipe. Now everytime I fill up I insert the fuel nozzle in the pipe that I insert into my fuel spout/tank. I have never taken a diesel bath since. What happens is the diesel goes through the pipe allowing air to escape the fuel tank outside my pipe. Normally what happens when you fill your tank fuel fills the fuel spout and blocks the air escape from your fuel tank this is what is causing the burping of diesel. I'll bring a few with me to RATS.

I have an insert in the fuel fill that is supposed to prevent the "burp" but only reduces it at the high speed pumps. At the slower pumps it works great. Besides we can all usually time the fuel fill at the end of the day so we are not losing driving time.
