I have been reading the Aux tank threads and I haven't found this specific answer. I just ordered a RDS 72771 60 gallon tank and install kit. I would like to keep the install as simple as possible, but I do want to put an inline filter between the aux tank and the OEM tank. My question is; Does gravity feed have enough pressure to push the fuel through an inline filter? If anyone has this type of set up any input would be helpful, like what brand/part number filter you use etc...
My zero turn riding mower has a small fuel filter on each tank and has never starved from fuel starvation. My fuel storage tanks at the farm are gravity feed going threw large cartridge fuel filters and has never had a problem with fuel flow. I don't see where you would have any issues with an in the bed fuel tank

Thanks for the insight! My concern was the head pressure required to push the fuel through the filter. I guess 60 gallons worth of head pressure should do it.
I think I would look at using a high capacity filter in order to reduce the restriction in flow to something approaching nil...
Fram HPG1 would be the one I install when I add my secondary tank. http://www.summitracing.com/parts/frm-hpg1
The issue that bothers me is the restriction from the non vented factory tank and fuel cap. My aux fuel system is electric pump fed and when I pull over and release the factory fuel cap there is a fairly strong whoosh of air that pops out. So, I conclude that the truck tank is vented but not freely. Anyone know if my finding is true and if it can be freed up? Is the truck tank vented but restricted to vent slowly?
I would hazard a guess to say that no American cars and light trucks are built with atmospheric vented systems any longer...
If there is any atmospheric venting, it is likely being done through a charcoal canister...
The good side of a sealed system is that the fuel lasts longer without being poisoned by moisture / dust & dirt...
I am hoping to just leverage the existing venting system for my second tank.. IE - the second tank would not be vented.

I agree that no car of late is vent to atmosphere. I do know the aux tank I ordered is vented, though I do have to fit a vent filter to it in order to keep bugs and other stuff out.
Edit:
The adapter that comes with the installation kit is vented also.

I have the 90 gal RDS with gravity feed on my 2011 F-350 6.7 and an inline filter like I use on my old gas engine truck. I have had to replace it several times in the 5 years that i have had it. But it works great.

I installed one of these filters with a site bowl at the bottom to inspect for any water. I found that it would not allow the RDS tank to empty. Once the level got down to a 1/4 of a tank, there was not enough pressure to continue to flow. May have something to do with this filter not rated for Diesel Fuel. Haven't taken the time to find a better solution.
