Using the EDT additive has not stopped the pump being a bit of a leaker on the 1993 Delica. We have done about 1500 km's since the end of January 06 and now when we park on the concrete a definite wet patch is there. So Trademe to the rescue ( I hope ) I have got a injector pump from a 4D56T being sent to me from a 1997 model, I will fit and see if it leaks, if no will sell my injector pump so someone else can rebuild and swap into there own leaker, if yes will get rebuilt and fitted and sell other pump. Browsing through the Pajeros etc for sale on Trademe there seem to be some 4M40 engines with leaking pumps and other vehicles leaking too. The NZ government dont seem to be getting much flack about the introduction of the LSD, I suppose leaking diesel was not a flammable as leaking petrol when the lead was removed and aromatics increased and under bonnet fires were common for a while.

Personally, I preferred to ring our "Ministry of Economic Development" - to discover (to my dismay) that no one there actually knew the difference between "Nitrile" & "EPDM" as a gasket/seal material (let alone had ever heard of such), Shades of what happened to the space shuttle Challenger there..................

The timetable below shows when sulphur levels will have to be lowered. In practice, diesel with reduced sulphur levels may be supplied several months in advance to ensure all diesel is compliant by the required date.

August 2004 500ppm
January 2006 50ppm
By 2009-2010 10-15ppm

so what's the ppm in other countries? - Are we attempting to lead the way by having 10-15 ppm while everyone else is still happy with their 500ppm? :?

Or are we way behind the 8 ball?

NZ is heading for 50 ppm. See following extract from Ministry of Economic Development (MED for short)
Cant wait for the 10-15 PPM diesel to arrive to really make the diesel pump repairs hit the big time.

50ppm Sulphur Diesel

The second phase in lowering sulphur levels in diesel occurs in January 2006, when sulphur levels are dropped further to 50ppm. This drop will necessitate chemical processing, using a new hydrocracker (which goes online 2005), that will also further drop the amount of aromatics in diesel and so may be accompanied by further seal failures. It is also important to note that for the first 2-3 months of the new refinery equipment's use the catalysts will be especially effective in breaking down aromatics (i.e. reducing levels of aromatics).

Coincidentally, at around the same time the diesel supply will be switching to its autumn/winter diesel composition. As explained above, this transition often causes an increase in seal failures especially if the transition coincides with hot weather, which is likely, given the time of year.

The consequence of these aromatic reducing influences all working at roughly the same time could result in higher rates of seal failure, when compared to the 2004 transition to 500ppm sulphur diesel. Alternatively seal replacements in 2004 might reduce the number of "at risk" vehicles thereby reducing the seal failure risk in 2006.

1Sulphur in crude does not appear free but rather is chemically bonded to larger molecules such as aromatics.

2Interestingly this blip in seal failures was not observed during the last transition.

The short answer is no as 1997 the seals in your injector pump would have been manufactured with the nitrle seals, BUT ( we all have a butt ) you cant help but notice the number of advocates of putting in an additive ( me included ). I put in some Wynns diesel fuel treatment every tank full. Others put in 1 to 2 litres of canola oil. I was sceptical that diesel oil and canola oil would mix so I tried mixing in one of the wifes glass measuring beakers and sure enough they mix perfectly well. Depending on how much maintenace you have already done on fuel filter replacement, I would leave old filter in put 1 litre of canola oil through with a tank, and then replace the filter. The canola seems clean out dirt and sediment in lines and hoses.
So the answer is no but its fun and prudent to put in an additive.

Thanks Healme, yip sure wont hurt to run a bit of additive! I must have gone past your doorstep on the weekend, went and did a bit of skiing!

just thought i'd let you know, my 94 fuel pump just let go, comming up the bombays after an eppic trip round the NI.. never mind, now the job of finding a trusted, non rip off, realistic repair?

Cool

Hi jonben

Sorry to hear about your pump! I always get worried when i plant it all the way up the bombays, especially when the boats on!

There is a guy who wreck's deli's who would probably sell you a 2nd hand pump for about $400, he advertises 4m40's on trademe, I might be able to find his details if you cant. Think his name is John( could be you) and he's in Hunua, east of drury, south auckland like!

jonben: oh...that really sux Crying or Very sad

One thing about the second hand pumps though....is that if the pump let go due to low-sulphur diesel...then getting a second hand pump will probably have the same effect.

Best have the seals replaced....expensive one off process.

All the best!

PS. Definatly worth keeping in mind what dougsgh said about where to get one from...as it may be the case that your pump is cactus (and not just the seals).
