Fuel blanket?

Anyone besides me need an interpreter to figure out what bgd73 goes on about?

My plastic tank is also far in the back, snugged between the passenger area and the spare tire. Only the bottom hangs down a bit. I also have something, which looks like a radiator hooked into the fuel line. It is under the passenger side. (It looks like it took a hit - ask the previous owner.)

It has two fuel lines coming out - one goes to the fuel tank, the other towards the engine.

My brother-in-law is a car mechanic, but didn't know what to think of it. This is the first time he's seen a tubodiesel this new. The only thing we could come up with is that fuel goes from the tank to the engine, where it gets heated. Some of it is used while the rest goes back to the tank, slightly heating the rest of the fuel. On its way back it goes through the radiator so it's not too hot when it goes into the tank.

Does anyone have better idea?

If your car has a coolant heater already fitted near the engine, dont worry about how cold the tank is.

If you need to convert the family car into a drag racer and supply more than 1 gallon a minute, I'd heat the fuel for sure

Else a small puff of white smoke would just be the condensation.

That's what I was guessing. Its just a small puff and is only there when I'm stopped.

Does the ZJ have a metal tank of some sort? it sure seems like it.

You need a set of beer goggles, Frank

after 4-5 beers it reads perfectly! LOL

Far as I know they are plastic. I think its just the stock gas tank skid

As for bgd73, I think he is saying carbs are the greatest, and we only have FI to please someone

^ thats what I got out of it. wasn't hard for me to understand what he was saying.

Check the volume of fluid in your brake reservoir.
Sometime the brake booster can allow a small volume of brake fluid to enter the engine via the inlet manifold with white smoke being the end result.
The amount needed is truly miniscule and the problem is often difficult to trace.
This is most noticeable after stopping since that is when the booster is used.

If your brake booster is letting fluid from your master cylinder, (in any amount) into your engine, you have much more serious problems than a little white smoke..

Especially considering that this would mean that your master cylinder's main cylinder seals are leaking, and blowing fluid back into the brake booster (a separate component), which is then being sucked through the vacuum booster line into the engine.

What this means, is that eventually, you're going to run short on brake fluid, and die. So yeah, you might wanna check on that.

By the way, there was a discussion about this in another thread, but I can't remember which one it was...

I said there, and now here:

Simple way to heat your manual car's fuel would be:
Add radiator from automatic version of your car. Plumb fuel through radiator at auto-fluid line openings.

This would at least heat the fuel to whatever the coolant was. Problem with this, is pressure differential and vapor lock. Might be a problem, might not.

Also, pre-vaporized fuel can cause your engine to run lean, as your injectors are tuned for a certain fuel density.. they can only compensate so far. Just like with carbs, you'd have to jet them down if you were using pre-vaporized fuel.
