Funky Fuel Filter Setup '04 Terrano

[Banshee]

Since having the new motor I've ran a few tanks of Bio and Veg through it on a previously Diesel only motor and the filter is becoming clogged. You can feel it, it's not pulling as well as it should and is becoming rather lumpy and hesitant.

My plan was to remove the current filter solution entirely and replace with new pipe, a priming bulb with one way valve and a glass filter however instead of the conventional setup that I was hoping to expect as per how my Maverick one was from standard, it appears the filter is being fed into some kind of exchanger and then being fed back up into the filter from that. I just wondered if this was standard on the later ones or if this is an add-on that someone has fitted

There are two more attachment points that currently have nothing attached to them which if it is a heat exchanger I presume would be an inlet and outlet for water from the Rad?

I'll post a picture in a few mins

Hey..
I am good at finding stuff,


see ebay item 261580527208

It's a bio fuel heat exchanger as you thought.
But look at the price...

So could it be a factory fitted option, but then not used, now that's unusual for Nissan they normally remove things like grease nipples off front prop shafts to save a few pence.


I can see a few members now disconnecting the interior heater pipe, and going through this first...:doh

Where would this be connected to and what, I'm going to rig it up

Theres no real point in rigging it up unless you run a twin tank.

As by the time it starts working the engine is got hot anyway and burns veg mix easy enough as is.

Whats the confusion here?

Considering I am running NEAT VEG only at the moment my truck does not cough or stutter the tiniest bit atall in mornings since my glow plugs have been changed.

really, there is no diesel in there :thumb2

Never seen one like that before & mine doesn't have this set up

I had something similar on my old Toyota hilux. I wonder if it's what used to be called part of a winter kit. Like 2nd battery and engine heaters etc :nenau

here is my set up

Looks like small plate heat exchanger as found on combi boilers. Hot water goes round and warms up the fuel...

The item in the pic is a small brazed plate heat exchanger, one side must be plumbed into the water system the two open pipes would be for heating the fuel, but as said only any good if you run two tanks as engine will need to be hot for this item to work, Rick

So of a veggie user you would have to start up in diesel whilst heater heats veggie, once veggie is warm you swap over to it? :nenau

 

[AlexD333]

Oh crap sorry banshee, I didn't see the finned bit underneath, thought you were taking a bad pic of the fuel filter setup :doh

Apologies...

Yep :thumb2 4 way switch over do das on fleabay :thumbs

What I do not understand is my LPG/petrol motor also has an engine heated LPG regulator but I can start on LPG no problem, true to say I have yet to experience it at sub zero temperatures, maybe it is then that I will need to start on petrol and switch to LPG, but may never find out as will be scrapping that one well before winter sets in, Rick

 

[makeitfit]

It's not so much a regulator but an evaporator . Even when cold the relative difference between the gas liquid in the tank and the intake air temp will still get the LPG to evaporate just not as well in very cold conditions. Then you have a spark to ignite it. The cold veggie stuff will congeal in the system in very cold conditions, so the problem then becomes squeezing the toothpaste like fuel into the cylinders. Then you get to compress it enough to go bang

A quick thought that occurred to me, if you have a second alternator setup, you could surely set up the following

A second battery running off second alternator
A heating kit for veggie pipes ect
The second battery would be solely responsible for heating the pipes before you even crank the engine
It would not matter if the voltage drops right off as the second alternator would charge it back up anyway.
This way you would only need 1 tank
Whatcha reckon :nenau

Trouble with heating veggie oil is

You need the heat all of it, from tank to engine, every thing.


Mine runs better when engine is warm so oil has been warmed.

Boot floor is nice and warm too..
