Yeah, like I said before, everything has a fluke.. Nothing mass produced will yield exact results everytime.. I have no ill words to facet, or any of it.. Its a great pump, just need more fuel than its meant to push. Most things only work in their application.

Thanks for posting this info. it sounds like these pumps are just a touch under power for any turned up turbo engines. i think i would prefer to have a pump that can supply plenty of fuel and then regulate it down to a good pressure.

Agreed. I just bought the Carter rated for 8psi and 72 gph. It won't overpressure, and won't starve the engine... In all reality, we only burn 5-6 gph, but with all of the cooling and lubing the fuel does we need much more, and it becomes really hard to calculate when you factor that in.. So, overkill it is.

The bowl looks clean, maybe, there is something in the line itself lodged in an odd way where it cant clear the line. The only reason I'm not just buying another duralift, is because even when it was working as designed, it couldn't keep up with the IP at heavy throttle.

spmetimes algae can appear as a brownish l skim layer that forms over the screen. if you look at the bowl itself, it looks like theres nothing in there, but you actually have a hard restriction forming over the screen. The problem with a screen instead of a filter element is it will skin over and clog rather easily where a filter element absorbes contaminants into its element at depth over time. The advantage is, you can clean the screen quickly and be on your way., but in the case of algay, that stuff has a nasty habit of being smaller than the screen and if theres any present, you can be sure some got through and it gums things up fast.

And it may very well be possible that I have more algae in my tank than average, my tank pickup has been 1/4 tank faulty since I've had the truck, which would let water sit on the bottom of the tank.

EZ and 6.9dieselfreak had failures too. I can tell you, the Duralift in my F250 isn't as impressive as the one on the F350. Still wonder if there isn't a better option for these IDI's, especially with mod'ed IP's/injectors.

I can go from 6-7psi to zero in the blink of an eye (or throttle LOL).

You can pretty much bet money on it. Big truck tanks are shaped round for a reason and it's not to look cool. THey set the pickup tubes a good inch or two above the bottom depending on the size of the tank and you never draw off the bottom so you dont pickup the crud that settles down there, then its part of annual service to drain the tank from the plugs that are fitted on the very bottom of the tank , depending on the size there can be anywhere from one to 3 drain plugs to make sure to get all the crud out, drain, then flush ans part of service, then shiney clean tanks go back on the road. You would be shocked at how little crud it takes to shut an engine down once it gets to where its sucking up the pickup tube. One of the ways to get company drivers to pay more attention to where the heck they are fueling at is to make them watch as you are pouring the remains of the drainesd fuel through some cheesecloth and see the junk that gets caucht. You wouldnt believe how rusty some fuel storage tanks are along with all the other critters etc.
Most european diesel cars have drian plugs as well, but most american diesel pickups and passenger vehicles were never fitted with them. They just expected the junk to be sucked up and delt with by the filter system . THe old GM diesel cars used to have nightmares with this. as they had zero provision at the factory to deal with water and sediment in the fuel

If youve been running like that for a long time ,it would be a real good idea to drop the tank and clean it out . If you take it to a good radiator shop thay can have the thing like new ( its kind of hard to clean a sealed bottom tank with a lip)

Only straight number two here, since the day I bought it.. Nearly.. The month I bout the truck (3yrs ago now) I accidentally filled it up from empty with straight kerosene.. Ran fine actually, but I stopped at every single fuel station and topped off with diesel until I had bought a full tanks worth of diesel.

Diesel and kerosene are the same product. Its kerosene is dry.. No lube in it. Wont harm the pump if you lube it with oil or atf but add something to lube the pump. Kerosene comes off the fractionation tower a little higher up than diesel so its lighter and cleaner. Gasolene is higher up than kero and white gas is even higher up...
