You're not allowed to build your own kit.

 

Please ignore my previous post. I noticed David Kelley changed on how the tank is vented now. Caps the original vent hose and moves it to the back of the tank with a bulkhead fitting. Still 3/4" ID hose.
Still drawing up the plans for a vent without dropping the tank. Going to add a second vent on the hump and T into the current vent line located near the top of the filler neck.

Here's a pic of Dave's vent-kit mod installed on my truck. Great bomb IMO. If it does not appear there's a pic in my gallery.

Just got my kit. Going to install this weekend and filler up.

 

After filling, I fill a 5 gallon fuelcan, drive 2 miles home and dump it all in.

 

i have been tempted to build my own, as i found what could be a perfect fitting for the tank [90° bulkhead fitting to 3/4" hose barb], and now found a place that sells [although, it is a good 2 hour drive from me to the place that sells it, and the distributor is 30min from me, but can't sell to public ] i was going to do it this year, but didn't have time... gonna be a spring project i think..

NEVER do this on a high pressure common rail system! if you were dumb enough to do so, and you got sprayed by a stream of HP fuel, it could cut your fingers off and/or give you blood poisoning and/or you could die...

yeah, hurts eh...? at least my last tank at least the fuel was less than $1 a liter... [and if i would have filled up a few days later, i could have gotten it at $0.899 instead of $0.979 ]

 

I haven't looked at my fuel tank, but if you leave the current vent uncapped will it not spill fuel out when you fill the tank all the way up inside the "hump"??

 

Hey...speaking of...would your Ram Air III work with my homemade torque tube??

 

Spool Up new vent kit plugs the original vent on the tank.

I'm planning to leave the original vent intact and just T into the line with the new vent line.

For the guys that have had this mod for a while now, how is it holding up? My worry is that I'll be putting a hole in the top of my tank, only to have it start to leak 2 years from now and have to buy a whole new tank. Thats something that I don't want to have happen! But the prospects of not having to spend forever at the pump would be nice.

Right. I understood that. I was under the impression that there is a "hump" at the rear of the tank and that the current vent is at a lower elevation than the top of that "hump". So, if you put a new vent in the top of that hump and then fill the tank so full with diesel that even the hump is full of fuel, it seems to me that the lower original vent would start flowing out fuel if you didn't cap it because it is at a lower elevation than the new fuel level.

Maybe I just need to crawl under my truck and look at it.

 

Well, being a vent, isn't it SUPPOSED to leak?? It shouldn't really get any "wear and tear" so I can't imagine that you'd ever have any trouble with it.

 

Ah I'm still pretty green on these (only owned for 2 weeks) but i now understand the difference in the old and new injection systems. Pardon my ignorance.

 

The current vent is tied to the filler neck, which is positioned higher than the hump on the tank. As long as the old vent is sealed off or a T fitting added I don't see an issue with leaks. Our tanks are not vented to the atmosphere unless you're refueling.
