Lift pump HELP!!

[madmaxdmax]

I am in the market for adding a lift pump to my Lb7. I know of the benefits of adding one, however I was told that it is highly recc. especially since I will be running bio once I get my set-up working. What type of inexpensive/reliable unit should I consider (if there is such an option)? I have been looking into the ppe single unit since it seems economically priced, but any other input is appreciated.

I like this setup that neversatisfied has. I think it is a super diesel brand. Only runs when you hit a preset boost IIRC. Not sure about capatabilty with bio.

[madmaxdmax]

Rick,

I saw his set-up but I am looking for one that run continuously, in order to eliminate the air bubbles and inconsistent fuel flow issues I may face when running an aux tank with bio-diesel. I know that everyone has their own opinions on the differnt mfg. of lift pumps. Just trying to get an idea of what works best for the price as well as what set-up is recc. as well.

How does an aux tank with bio relate?

[RickDLance]

I've got a Fass and I've never had any problems. It's gotten a little noisy lately though.

I also run an auxiliary tank, but I simply pump from it to the OEM tank while driving. Keeps all the BS in check. ;)

I know that it isn't the cheapest, but we use DPP Fass pumps. They get rid of all the air, run all the time, and are almost silent. Some of the older pumps were noisy, but the new ones are really hard to hear. I have heard of people running holley pumps, but have been told that they do not get rid of the air, and may not be suitable with Bio...

I don't run a lift pump, but I do run bio and an aux tank... Where is the air coming from? I have my aux tank gravity feed into the OEM via the filler neck, and the standard fuel system takes over from there...

I plan on installing an aux. tank for more fill capacity. I hate having to stop so frequently for diesel on long road trips. I figured that I would try a B20 mix in both the oem tank AND the aux tank. The aux tank (if I can find one that will fit under the roll top cover - 18" total height from bed to top of side rail) would connect to the oem fuel lines and have a cab mounted gauge and switch so that I could travel longer distances between filling.

HMMM.... I was told by another bio user that I needed to add a lift pump in order to run bio. If I don't even better ! I saw the fuel neck connection in a Norther Tool catalog I have. How well does that work? Do you have some type of in cab controller or does the gravity feed NOT over-fill your oem tank ? Pics would be great reference for me :thumb:

[blksmok]

I'll get you some pics. I have the filler neck "T" from Northern and it works perfectly. It never overfills and I have the valve open all the time. I can even remove my OEM cap and it won't flow out. I don't know why you would need a lift pump for running bio... I don't and neither does my friend who has been running it in his medium duty for about 2 years now... Now if you were running SVO or WVO, I could see a need....

I just t'd into the vent line. I run a Holley pump with a check valve on a five minute timer. When my lower tank get down to 1/2 I turn the timer on and it shuts off the transfer just over 3/4 tank. Really has worked good for several hundred thousand miles on several truck now.

Okay...now I gotcha ! My guess is Dan (the bio guy) was thinking that I wanted to run SVO instead of Bio.

I seem to be having a streak of bad luck (usually) second or third in line) to getting the magical "wvo" from local eateries. What's the deal...are people starting to get it finally?

[RickDLance]

Here's my setup.

[h2oskibumz]

HMMM.... I was told by another bio user that I needed to add a lift pump in order to run bio.

Don't believe everything you hear... I have run 250 gallons of homebrewed bio through my truck this year, 3 tankfuls at B100 level, the rest in 40-70% blends. No lift pump.

I should qualify that and say that I am considering adding one, but it has nothing to do w/ the bio. In addition to the factory filter I've recently added a 16 micron with h2o drain (3244) AND a 2 micron (3674) in the usual frame rail position and I feel that it CAN'T POSSIBLY be good for the CP3 to pull fuel through all 3 of them!!!

Hmm. Probably going to be asked for pics of that, huh? Basically its what everyone does, and looks just about like the one Saratoga did in the DIY pages.

Cripes I'm a slow typer!! While I was posting that there were FOUR other posts in thread...

[madmaxdmax]

Okay....back to the drawing board ! It seems that the general opinion is that no lift pump is needed to run the b20 from the aux tank. I forgot to add that I have an in-line 2 mic. pre-oem fuel filter as well. Will this cause enough strain to justify the lift pump, or am I still okay to not add one ?


Does anyone know of a good resource to obtain a aux fuel tank with a max. height of 18"? I would like to install the tank between the fender wells.

Sounds like you "peck" the keyboard like me !

Fuel is heavy. You really want to keep any tank install right against the headgate. I know that sucks w/ a rolltop cover and will really limit your options (THE primary reason I have a fold a cover, though if I have it off the truck now because my 100 gallon farm tank and pump are too tall!!)

Northern tool has a 37 gallon or so that is really low profile and may go under your rolltop's box... search "RDS" on the northertool web site. As soon as I can fund it I'm going go get the 60 with toolbox. At 19" tall it should fit perfectly under my cover.

Actually I typed 1/2 that, and then had to stop and get my 6 year old back to bed... "daddy, my leg itches, can I have some lotion??"

Finished it up and posted and viola... you guys made me look silly! Its OK though, I can handle silly...

[blksmok]

Like said above. The 37 Gallon RDS tank is only 9" tall. Where were you a couple months ago... I just sold one.

I now have the 60 gallon with toolbox. :thumb:

As for the additional filters, I don't know. I have a 2 micron water blocking filter on my bio processor that all the fuel goes through before I even put it in my truck... It's easier to change that way too. :thumb:

[h2oskibumz]

Oh yeah, I remember that... it was "The Tank That Would Not Sell" I watched it and watched it thinking SOMEONE CLOSE WILL SURELY BUY THAT! I guess eventually someone did. And now you have the one I want.

Here is a link to the 37 gallon:

Looks like I will have to move my on-board air compressor and storage tanks as they are currently mounted up against the headgate. The clearance under the roll top at the head gate is even less - more like 12 ". This is due to the roll top being stored in the "box" when retracted. Hopefully I can find a low profile tank not only for the clearance, but to keep the tank stable in case of a sudden stop-:t

skibum,


Thanks for the link. Maybe avail. in poly by someone else ?

[BudTX]

FASS here too, with no problems. I put a rocker switch in to manually shut it off when I want to (like when changing tunes on the programmer).

I'm not sure if a poly aux tank would be DOT legal... I've only ever seen metal. I could be wrong, but I'd check into it.

Thanks. I just want to be sure that I am legal, and at the same time bio compatible

Make sure you are legal especially going to the dunes. The Ca. police are serious about all that stuff.

yeah steve if the Ca po po wont let you dump water in your camp site...im sure they wont let you cross with bio in a plastic tank.. but then again we all strore gasoline in plastic containers. chemical makeup also has a role in it too.

I talked to a engineer at a tank company last year about making storage tanks and larger tanks for our trucks last year...

He told me that the research, testing, DOT compliance and costs for the molds prohibited his company form making tanks for our trucks.. That's why almost all the tanks are made out of welded steel or aluminum, lower manufacturing costs..

Good to know...now my search for a plastic tank has ended. Looks like I will invest in an aluminum tank. Currently looking at the RDS one from Northern Tool. Guess I better start doing nice things for my sugarmomma - I have already gone over budget for this birthday :lol:

[swatkins]

I like my 60 gal RDS tank... I would make sure I inspected it before I purchased it though. The first one I looked at had really rough welds around the filler neck area...

[madmaxdmax]

I guess I could always refuse shipment when the ltl truck gets here. Truck shippers can get a little rough and I WILL definately inspect the shipment before accepting it ! Time to place an order....):h
