Hi everyone,
I have a T25 camper that has had a K-Jet 1.8 Gti Engine conversion. Under the van i found this abomination of a pump setup:
(http://i176.photobucket.com/albums/w182/bossman187uk/DSC_0022.jpg)
Now it looks old , especially what i think is the filter you can see just behind the sill. Can anyone tell me a bit about this pump? If i wanted to replace the whole thing, with housing etc what are the part numbers on GSF or somewhere i can get it?
Also any idea on prices?
I find it hard getting parts for Kjet engines as most places seem to give me the wrong stuff. Is this an easy replacement?
Thanks
-
idealy you want a K et pump assembly of a k jet audi, ( feed pipe from tank large like on t25 ) a mk1 or 2 golf k jet pump will work tho
-
and get shot of the hideous little filter - you only need the big cannister.
Thought the guy who did the conversion 'knew what he was doing'
It's f*cking hideous so far.
-
is the little thing a filter? I thought it was an accumulator ?
Anyone know where i can get all this? Once i have it ill get an auto sparky to wire it up properly.
Cheers

if it is accumalator leave it there buit get the proper vw fuel filter, big shiney can, really you want the pump acumalarot and filter all on it's bracket and fit the lot as it should be.
as for the wire's i'm not going to pretend i din't see them

lol me neither, as i said i bought the van a few weeks ago and the previous owner didn't know much about it either, so kinda learning about it as i go along, but as soon as i saw this i thought i need to get it sorted asap.
It works fine, so do you think a new filter, secure fitting and an auto sparky fixing wires should be ok? I have never seen a fuel pump like this before, i am assuming its one designed for a K jet system, but again I have no idea. Can anyone conform this is ok for my engine? if not ill change it.
Thanks for all help guys, life saver

That uber rusty cylinder just poking out the top of the photo looks like the accumulator to me.

its probably gonna cost you about 300 quid from GSF cos your gonna need the plastic housing, filter, accumulator, fuel pump that sits inside the plastic housing, and i couldnt see any return pipes there either, oh yeah you will need the mounting bracket that holds the whole thing to the bottom of the vehicle too, ha ha might wanna get a haynes manual mate its a bit of a ball ache to do properley!!
-
Not what i wanted to hear :(
The return lines are on the other side of the sill, and i know for sure there is a filter for it in the engine bay.
I have looked about but it seems most K-Jet fuel pumps being sold seem to go in tank, are there 2 types, internal and external or do they work together?
Could this be a completely bespoke pump as its in a T25 so to work with the current fuel tank?
I am stumped at replacing this as I cannot afford a fortune and this one works, so thought a rewire and secure fixing might do the job.

Ignore whoever the hell Nixon is. If the pump is working fine, leave it there. It looks very much like one from an old K-Jet Audi, possibly an 80 or 90.
These (as I think Danny's said) have a bottom feed tank, so don't need the lift pump, which is the in-tank pump fitted to the Golfs, which have a top-feed tank. The Audi pumps look just like what you have and have a simple metal bracket that bolts under the car, with space for an inline pump (just like yours) on one side and a filter/accumulator on the other. A scrapyard mission, or call to someone like All Audi in Bristol might yield the neat braket that will allow you to secure the pump and accumulator under your van.
I'm confident that you will have a return, as the 2WD T25 tank *as I recall* has feed one side, return the other. The only minor issue you might encounter is fuel starvation on low fuel level and hard cornering - there's no 'swirl pot', so the pick up might take the odd gasp of air, although the 'acculmulator' (big silver cannister) will help to eliminate sensitivity to this in your situation. Someone might correct me on this, but the only filter you should have is also the accumulator. remove any other filters fitted on the set up, as they might screw your fuel pressure under load, causing the motor to run lean and go into detonation.
Bear in mind that the injection pump on T25s was only held on with a single clamp, which regularly rusts out and is replaced with a ziptie by most.
Don't get bent out of shape over this. Make the wiring safe and at most get a fuel system pressure test run by a specialist to ensure you're not running low pressure, which WILL kill the engine.

As usual thanks for the sound advice diamond. :smiley:
I think the filter arrows pointed back to the tank so i assume it was on the return line.
Its very hard to see but behind the filter on the next sill is a bent aluminum plate in the shape of an L which i am guessing used to hold the pump prior to the cowboys installation.
Do accumulators need replacing over time? as mine looks rusty from the outside and i know has been sat for years.
If anyone has the ETKA diagram for the original Audi fuel pump that i have installed i would be forever indebted.
Sorry for so many questions guys, I have done a some DIY mechanics but this scares me a bit as its not T25 or K-Jet specific, and as i dont know who installed it I'm pretty much on my own :(

filter and accumalator are seperate units. VAG fuel injection filters are large metal canisters. also very inportantly the filter goes after the pump on the pressure side.
reason been is the high pressure pumps cannot suck very well and restriction to fuel feed will cause problems the filter is there to protect the injectors and metering head, the pump can deal with crud when there getting old they more than likely create crud.
it's not massivy urgent but i would get that crappy plstic filter from there it's not big enough and there brittel one good wack and it may breack
-
yep as above, the pump looks like a MK1 GTI tintop setup, and I can see the accumulator is there too. Just need to fit a filter along the line somewhere, MK1s have these in the engine bay on a bracket in front the front of the fuel metering head, this would probably be eaisest for you?
Accumulators do fail over time, generally all that happens is it makes the engine hard to warm start, as fuel pressure is lost and the fuel in the lines evapourate due to engine heat.
In addition if you do suffer from fuel starvation get a fuel reservoir from a late MK1 Cabby/scirocco, or a MK3 polo. this will give you a fair bit of fuel reserve.
