CONSIDERING FUEL SUMP. THOUGHTS?

I have a fass on its way to my house now. I have been reading about the 1/4 tank problem, and solutions. I now drive a company truck so the wife drives the 6.0 every day, and she is bad about letting the tank get low before she will fill it up. I can't chance her being stuck on the side of the road. So i'm thinking of getting a hellmanns fuel sump (or somthing like it) to slove the problem. I have done a litlle searching on here and haven't really seen much talk about it. I did see where Matt talked about building one for sell as well. I have emailed them with question about this. What is everyones thoughts on putting in a fuel sump? Seems like a bunch of dodge guys, and chevy guys are doing this with no problems.

You may be trying to solve a non-existent problem.

I routinely run my tank to below the E line, and have had no problems.

If you are really freaked out about it -- install a fuel filter / accumulator after the pump but before the engine --- with a check valve and an air return line.

I think a sump is a "must have" w/ the FASS system.

gearloose,
Your truck is stock IIRC. You would not have the problem that i'm talking about. Yes with the stock fuel system you can run the tank almost completly dry, but when you install a FASS system and there pickup tube there are problems (from what I have been reading) of the pump cavating when the tank gets down to 1/4 tank or so. I have been reading about this all morning and the only solution I have really seen that makes since is to install a tank sump.

yeah I think the 95/90 does, but I have the 150/180 coming in. I haven't seen it yet, but from what I can tell it needs a larger pickup tube. I could be wrong that's just what I have been reading. I will know more next week I guess.

I would do it in a heartbeat Scotty. Joe Hellmann is a stand up guy. I've met him at a couple of diesel events. It's a quality piece.

Most people don't realize how much they cavitate their fuel pickup when the tank gets really low until they get a fuel pressure gauge. Some people never have a problem with it and some have it constantly (on a low tank).
