Thread: colour of diesel

No that is not the colour of standard diesel .
Tis a concern but not water infected if you left your sample sit which is does not look like .
Id say more like Bio but who knows .

It does look like biodiesel that has been subjected to cold temperature. It sometimes goes cloudy like that but will still burn fine. But normal pump diesel shouldn't go like that. A 2 micron filter should be more than sufficient for any fuel, if it runs fine just keep burning it.

Even in a Puma engine? It runs a little rough on idle but settles under throttle.

I'm presently fault finding for a loss of power on hills at WOT. The turbo is sounding unhealthy which is being looked at when i get it to the local mechanic. I'll also investigate the other usual suspects like the vacuum control valve, hoses etc. It's boosting to 22psi (according to Bell Auto that is standard for the Puma engine) but it feels like there is a fuel limitation at full boost.

I would drain the tank and fill again with clean fuel, That "Fuel" just doesn't look right to me.

I would hope i'm wrong but I'd say its water in the diesel. Unfortunately I have a bit of experience in this matter.

Your sample looks at lot like mine did when I drained the tank, mine looked a bit more greenish. It took about 4 or 5 weeks for the water to settle out of my sample and there was only about a teaspoon in 1 liter of fuel.
Unfortunately the photos of the samples I posted seem to have been deleted. Attachment 124441.
I think I still have the photos at home and can repost them here if you like, but will have to wait until tonight.

I had a few days of thinking I had lost a bit of power, but because I was towing a boat in pretty bad weather, thought it might have been that.

If you do drain the tank, keep the fuel as proof of water contamination as your insurance may cover it.

Edit.
MLD - sorry I really didn't answer your question. I'd drop the fuel and get new stuff. Also there is a fuel line top front of the motor that you can take off. when you turn on the iginition the lift pump will pump out about 1/2 a litre. You can use this to get fresh fuel into these lines. Don't really know how to flush the return lines though.

I'd also be calling the mechanic and asking what he put in the tank! If it is bio, perhaps not an issue per se, but if you're trying to sort out a power loss situation, I'd be stating with fresh, clean fuel as Step 1.
Draining the tank yourself is not that difficult. Get onto Mario and order a couple of extra fuel filters. New fuel and filter, give it a good run, then put another filter in, and go again. Rinse and repeat until fuel is clean. Way cheaper than pumps/injectors.
