Completely unnecessary but knock yourself out.

It gives you three options, the easiest for you is to simply replace the fuel filter and pour the neat jizz straight into the filter bowl to refill it before refitting the lid and starting the engine.

I want to do it by sticking the pipes into the liqi moli but its very vague with just a " Disconnect the fuel line, put the end in the can of Diesel Purge and start the engine "

I know right, modern engines are like magnetic witchcraft, if only it were REALLY SIMPLE like one line into the filter from the tank lift pump and one line out of the filter to the tandem pump!

Are you trying to fix a problem with the engine?

Not really but i am trying to prevent a future problem My car that  i bought a few months ago is 12 years old and has only done 30K miles so obviously has only done short trips , i have finished the maintenance program i had set myself ( new oil,filters,fluids EGR clean etc etc ) apart from an injector clean, so i would like to do it once just for my piece of mind  to see if the engine runs smoother and i get more MPG. The way i figure it is it wont hurt and it just might do some good.

The vids i have seen how to do it have all had 4 hoses on the fuel filter and i have only 2 ,so what i am trying to find out is do i just pull the  feed and return fuel pipes off of my filter and put them in the Moly after connecting  a short piece of pipe to loop the feed to the return on the filter, or, with just my 2 pipes on the fuel filter is it a bit more involved ?

 

Sepulchrave did actually give you the best answer for this.

Just spotted your post. Why do people feel they have to try and belittle other people  with sarcasm ? Is it because you know more than me about diesels it makes you feel superior in some sort of weird way ? This is the 3rd month into the 1st diesel i have ever owned so i am learning just like you had to do once upon a time. If you cant or wont help with questions dont reply to them.

He gave me AN answer, but ( according to him, me being a thicko) it was a bit too  vague  for the way i wanted to do it

The way you want to do it isn't necessarily good.

The filter housing is just a bucket with a lid, isn't it, with two hose connections on that lid; no other connections anywhere else on it? So by doing it as suggested you get your gunk into the system, re-close the system, then run the engine.  You'll probably have to extract some diesel from the housing to make room for your potion.

 

I realise it may not be what you envisaged, but it does sound logical to me. 'Stroppy sep' does offer useful info if you can just bat away all the extraneous stuff.

Until Wino came along I was the ONLY person helping you, I thought I was being pretty patient but it was starting to get a bit silly.

So I stung you into waking, get over it.

This is the way i wanted to do it ,but filling the fuel filter up with Moly was always going to be my second option.

Helping !! its a good job i have a sense of humour . Just remember other people read these posts so your making yourself sound silly by trying to cover up that your a cantankerous old arse hole by saying you done it for my benefit.

If you post some decent pictures of the fuel pipes in the engine bay i'll tell you what to connect where

I'm not trying to cover anything up, I'm not the one trying to do something completely unnecessary without the first idea of how to do it.

I lost patience, big deal, there are some users here who's posts are basic exercises in futility, yours falls into that category.

Like I said, knock yourself out.

 

 

Take the pipe marked with the green from the filter where the red dot is and put it in your magic unicorn urine. (this is the supply to the tandem pump)

 

Take the pipe marked blue from the hard line on the engine and attach to red dot connection on filter (this will put the lift pump in recirc to the tank)

 

You will then need to find another piece of pipe to connect to where you have just removed the blue hose from and put it in to the uniorn urine as well.

 

DON'T attach anything to the top hard line as this is coolant.

Thanks for that

I will let your reply speak for itself

Yours already did, I can handle criticism without resorting to abuse.

There is a much easier way to clean injectors. Buy a good quality injector cleaner or combined injector cleaner/fuel additive and just dose it into your fuel tank when you refuel.

 

I highly recommend http://www.millersoils.co.uk/products/diesel-power-ecomax/185

 

It available for a little over a tenner. Treats 500 litres. Really works, adds lubricity to the fuel, protecting pumps and injectors, and boosts Cetane which makes your diesel run smoother, particularly noticeable at idle and slow speeds. Works well with your PD engine and gives a modest mpg boost through cleaning and restoring the injectors original spray pattern, reducing exhaust black smoke.

 

It takes 3 to 4 tanks to get best results but you can double dose it and along with a few "Italian tune ups" will get quicker results for those with heavy carbon loaded injectors, and combustion chambers.

 

 

 

Alternative.  a year or so ago, I did circa 4k a year . No hot trips etc. Then I got problems. Sticky EGR shut off valve. Now, I do a once a week Italian tune up, and at every opportunity.  One thing I've found in over ten years of owning a 1.4Tdi is that they do not like to be an old folks shopping trolley. They seek to be a close relative to big bro- the Vrs. Take it out and enjoy the handling and see how much pleasure you can get out of a 70bhp engine . Me- I'd love to map it up to 100 bhp, but that would need a brake improvement to VRS discs.
