I don't know, however I do know that the Shoguns always stuck with the mechanical pumps. Where as the Pajero's only had the on the earlier ones.

From the research I did a month or two back, it would seem the EDC pump seems to be upset by the fuel being too viscous, but is perfectly happy with SVO/WVO and diesel mix as long as it's suitably heated to ensure it's thin and runny. Hence it's probably much better to run a twin tank setup on an EDC pump 2.8, in order to get the engine up to temperature so a FPHE can thin the veg oil sufficiently.

The problems appear most obviously at idle if the pump is struggling with fuel that's too thick, so at least it should be fairly easy to just chuck in a load of diesel if it seem unhappy.

There certainly seemed to be plenty of people not scared off by the uncertainty running SVO (or at the least a 50/50 diesel/SVO mix) on EDC pump 2.8s, but information is very hard to come by as I think a lot of people just regard it as a 'don't do it' thing rather than trying it. I think 100% SVO/WVO will almost certainly require twin tank and FPHE, but I couldn't find much in the way of reports of people running that.

First of all I second everything Rich has just said ; its all down to the viscosity of the oil but there's not a lot of info on the EDC equipped models ; but hopefully that'll change!

I've got an EDC pump equipped 2.8 SWB and it quite happily starts, drives and runs on a 70% diesel / 30 % svo mix with no mods Cool

The only thing I need to do is raise the idle as it can be a little lumpy on tickover.

I've just got all the equipment together to rig up a twin tank system (FPHE, 2 x 3way valves etc, metres of hose etc!) - hoping to do that in the next couple of weeks (weather dependent!) and then I'll be upping my mix to 50/50 and then beyond. Will report back with pics and more info.

But for the moment, you should be good to run upto 70/30 fine ; best test is run your tank as empty as you can then mix a 7 litres of diesel with 3 litres of svo and pour in. Start it up and go out for a couple of miles drive to get it through the engine, filter etc ; if it works then awesome - if it struggled like crazy then add some more diesel and save up for the bits for a twin tank setup Smile

Can you run Shogun DiD engines on a SVO / diesel mix?

Advancing the pump 4 degree's can cure this it also helps when using blends up to 100 % oil.

I am also looking for a new to me pajero.
2.8 automatic long or short body for the wife.
Still keeping the old one for my work horse.
Would swap my rover 75 auto estate or cash,

Ta rich...

Thought I'd ask just in case a DiD is worth a look at etc...

What pajeros have the EDC pumps?

do any mk2 shoguns have EDC pumps???

Think the switch-over for Pajero's was 96 but someone best confirm. The MK2 Shoguns are all mechanical.

Pajero 2.8s from round about mid-1996 and the 2.5 in the L200 and Sport from around 1999 onwards have the electronically controlled pumps. When they're working properly they are a good thing, getting a noticeable amount more power and slightly better economy. But if they fail, they're a lot more expensive to repair than the old fashioned all mechanical ones.

Thanks for the info - does anyone know how easy this is to do on an EDC pump and whats involved?

Cheers!

I would expect the body of the pump to be similar anf fit the same as a mechanical pump. There are bracket bolts underneath at teh rear to secure it to the blcok and a nut either side at the front to lock it to the front casing. The pump body front holes are slotted to allow it to be twisted in the front casing so advancing / retarding the point (in relation to the crank/cam timing) that it squirts. Twisting it in the opposite direction to what the injection pump sprocket turns will advance the pump timing.
I bought a LazerTools diesel injection pump timing tool off ebay for £70. Takes a bit of sussing out to understand the destructioins though.
Fit securely in rear hole Shocked

Set dial, turn crank 30 degrees so needle stops moving, re-set dial, turn crank till dial reaches specification figure, check where the crank tdc pointer is at to get atdc pump timing figure in degrees.
