So, after installing my Duralift pump about two months ago, my truck ran and primed beautifully...for about a week. Then, I started running into starvation issues while driving, especially under heavy throttle. My pump I believe is turned up maybe one flat, so I didn't see that as the issue. I was prepared to just reconnect the old mechanical pump and use the Duralift as a primer when I went through and replumbed the fuel system under the bed.
Well, I took off the bed and ran SAE30R10 submersible hose in the tanks, with the brass t's on the bottom (I believe icanfixall recommended this? GREAT idea, whomever it was!). Then, noting that my truck still had the factoury fuel lines (the nylon coloured stuff with the little funky slip-on connectors) I decided while I had the bed off, I would replace it all with new hose just to make sure I had no air intrusion due to old seals.
The interesting part was when I took off one of the old slip connectors to attempt to reuse it for the elbow it had (didn't work, ran new brass). When I cut it off the old line, I noticed that it was full of little black plastic chunks. I assume they are from the showerheads (I removed the big pieces from the tanks). I believe that the new, constant high suction of the Duralift caused them to get sucked down the lines to the connectors at the solenoid tank switch, and clog the supply lines. This completely explains my starvation issue. I resealed it all with new hose, and added two little filter screens, one after each tank going to the valve. I've seen several more little chunks get sucked into my Duralift bowl, I assume the remnants that were in the switch, or other lines.
Happy to say, no more starvation issues. My Duralift keeps up with the injector pump just fine now!
Just figured I would share this experience with all of you, since I've noticed a few other people complaining of Duralift issues lately. You might want to check your lines for clogs.
EDIT: I have since switched to using screens on the sumps in the tanks themselves, that way nothing can even enter the lines. I didn't like the idea of replacing the elements on the inline filters I was using.
