is anyone else having problems with the new UL Sulfur fuel? 3 of our powerstokes have sprung leaks, and now our cummings powered freightliner. wtf!?!?! Its just eating through the gaskets in the fuel lines and blowing fuel all over the place. So far none of our VWs our Cat powered trucks have had a problem but its getting frickin irritating and expensive to keep replacing damn seals.

Really? What're those seals made out of? And what's new about the diesel besides low sulfur? :/

And I'll bet you haven't been dosing any of them with any kind of aftermarket additive like the ones Stanadyne and Power Services market.

Diesel injection stuff ain't cheap, what with Powerstroke unit injectors at $175+ for reman units, or maybe 450 to 750 dolla to rebuild a jerk or rotary mech injection pump.

At 15 to 20 dolla a gallon, additive is cheap. Especially when that amount will treat 300 gallons of fuel.

everyone is having problems. updating to the newer seals/gaskets will solve the problem, or run a quality additive like ^ mentioned.

i personally have used diesel kleen.

low sulfer (<500ppm of sulfer) has been around for years. starting oct. '06, the epa mandated the sale of ULSD (<15ppm of sulfer). the ulsd diesel has to have a specified amount of lubricity added to it to supposedly prevent the deterioration of rubber seals in fuel lines. another drawback of ulsd is a loss of power and fuel mileage. adding a diesel fuel treatment should help alleviate the power and fuel loss issues. unfortunately, many people are experiencing rubber seal deterioration. from what i've read, the epa is reviewing data and is probably going to have to end up changing the amount of additive that is in the ulsd fuel. fortunately, my truck is an '07 and is spec'd to run on ulsd and gm advises against any fuel additives. if you do choose to run an additive, i would also recommend Stanadyne.
