would you ever be interested in a one-tank solution? (or at least relocating the second tank under the vehicle somewhere).

as far as i've read, if you have heated fuel lines and allow for the pre-warm up this can be accomplished...

i value the ability to flip down the seats and haul larger items (i use a JL Vantage box for a subwoofer for example, my amps are under the rear seat). jack on the roof rack, etc... to maximize cargo space.

i would be really interested in ideas on a one tank system that could run biofuel or diesel at any given time...

i'll even be your guinea pig if you want to me to send a jeep your way...

my goal is a stealth "factory" look to the installation... that would pass for a normal vehicle....for the most part.

if it were me doing this, i would make it 3.5" and try to fit 33s. 6.5 is a little top heavy and that "24 mpg highway" from the diesel will be less than what you were hoping for if you're that high up.

but good luck!!

Yeah. The 6.5" kit is more than I needed considering I only want 33"s. I ended up going with a 4.5" AAL kit from rough country. I picked it up on craigslist brand new for half price (which is really cheap, considering RC is inexpensive to begin with). I'm runnin 32.5"s on 17"s. I get 11.5 mpg with a roof rack and toolbox on top with the stock 4.0.

Hopefully Koch will have his adapter finished by may, gas is killer at 11-13mpg. Lol.

Putting the tank underneath is not an option, due to there is no space and you want the tank inside to keep it warm. A custom tank could be made to replace were the spare tire would be and give you more floor space.

With WVO you have to start it on Diesel till it gets up to WVO temp (160) degrees and then switch it over. When you shut the car off it also has to be purged with Diesel to clean the lines and filters out so they do not plug up.

I guess the decision is Boom Box or WVO which is more important?

that's actually not a bad location, as long as there's no venting of gas into the cabin (maybe carpet it too to fit in better). btw the JL vantage box goes on the other side and is very small... so you can have the best of both worlds. pop the spare on the roof and your good to go.

mine isn't carpeted, but it looks like this (and produces big enough bass for most people).



.... would be sweet to be able to fill the secondary tank from outside the vehicle .... but that might be tough to do....
(i thought the secondary tank was for normal diesel just to start the engine, and you'd use the main tank for biodiesel??)

That would work, the tank could be the same shape as the panel and could be even have a carpeted panel over it. It could be filled from the outside with another filler neck to duplicate the factory one. It is not required but could be done that way. You want the WVO tank inside to keep it warm and use the stock tank for diesel. You don't want the diesel smell inside anyway.

Well guys, crapped on, yet again, by the EPA.

I finally got in contact with the guy who does inspections and whatnot. This is what he said:

1. The engine has to be offered for said vehicle as an option (in the states). If there was a diesel offered in the usdm XJ, then one could swap the engine in, and change the fuel type to diesel. He says this is pretty much how it goes nationwide, due to the EPA.

2. Another stipulation affecting swaps: even if I could swap in a diesel, said engine would have to be as new (same year as jeep) or newer, to swap in. The OM617 diesel wouldnt pass in my jeep (it's a 1999). I'd have to use a newer Bluetec or one of their newer CRD's.

3. He said you can retitle as a custom build, but it is very likely that the DOT would block your tag and try to screw you as soon as they saw the diesel box checked on your VIN. You could get away with farm use and trailering to OHV areas, but probably couldn't get it on the road.

4. Titling as a kit build isn't possible, at least in my district, as it's still clearly a XJ and did not sustain and significant body replacement or frame alteration.

So I guess that sums it up really, at least here in NC.

The only option I can see at this time is to buy a 1995 and down XJ and fly under the radar. Guess I'll start looking for one.

What happens if you buy the Jeep out of state and bring it in?

It still has to comply to state law before it can be tagged.

anyone know if using this exhaust would cause any problems with a future swap to that OM617 engine?

Borla Part # 140071 Cat back Exhaust
http://www.borla.com/products/produc...rod_sku=140071

my muffler is falling apart and i was looking to possibly upgrade to something like that, just want to make sure there wouldn't be any issues with the diesel conversion...

It shouldnt other than the CC.

What I mean by this is when you do the diesel swap, with any exhaust system designed for gasoline engines, you'll need to remove the CC (catalytic converter) from the exhaust system. If it isn't removed, it will quickly become stopped up with soot from the diesel exhaust.

In my opinion, if your going to be swapping in a diesel in the future, it would be a waste of money to invest money into that exhaust system. I say this because you will get the best performance and fuel economy by using a straight pipe exhaust setup with the diesel engine (no cat, muffler, etc, from the turbo back; just properly sized exhaust pipe, properly sized being not too big, but not to small).

If your intending to go diesel in the near future, and just need something to work until you do the swap, I suggest a cheap muffler from autozone or something.

If noise is not a problem a straight pipe would work, I think you will get tired of the noise after a while. One point to remember gasoline mufflers have smaller baffle holes then do diesel mufflers. If you use a gasoline muffler it will plug up from the diesel soot.

As far as I know, in PA it would require a full inspection and a reconstuction or special buld tag to get on the road.

Dont you love how the enviromental proitection idiots would stop you from doing something that would use less resources and be recycling old parts and another person's waste?
