Gday ALL,
Any experts on our syncro fuel pump specs care to take a look at and comment back here on this possible economical alternative ... much cheaper than Bosch.

A few years ago I was told by a T3 owner and subsequently agreed to by my local VW mechanic that a cheaper suitable replacement for our fuel pump was one used in a Commodore V8 EFI vehicle. This one below seems to do that.

Goto: http://cgi.ebay.com.au/Electric-Fuel-Pump-EFI-Commodore-VL-TURBO-V8-Bosch_W0QQitemZ280340936083QQcmdZViewItemQQptZAU_Car_Parts_Accessories?hash=item280340936083

I'd buy one if this forum gives it's blessing.

Cheers.

Gday ALL,

Just wondering if anyone took the plunge and bought one of these fuel
pumps on ebay?

First dayI looked and reported here, there were 4 available.

Yesterday they were all gone. Co-incidence perhaps?

Cheers.

Ken,

No doubt someone was just asleep at the wheel I see the seller you pointed out has another for sale today. There have been dozens of these flooding the US Ebay listings for just about any vehicle. I was considering getting one but like you wanted to wait until someone else reported on their experience.

Gday Ben,

You've no doubt heard the saying .... "you can lead a horse to water but you can't make it drink".

Here's my enquiry to the ebay seller ........

Dear na2t_performance,

Hi, do you have any knowledge whether or not this would be suited to a VW 1990 T3 Transporter van with a stock 2.1 litre WBX watercooled motor with Digifant EFI? The difference in your photo to the VW Bosch OEM fuel pump is the VW OEM has push-on spade connectors which yours doesn't. Obviously the correct specs would be more important. Or else maybe you have available the correct equivalent fuel pump for the VW. Cheers.

Here's the sellers reply .......

Hi, an 070 pump will be a direct replacement for your pump with the only change required is cutting off your electrical connectors and crimping on the ones supplied with the pump. 5 min job. The 070 pump will flow a little bit more fuel than your stock VW pump, however the fuel pressure regulator will keep a constant system pressure (regardless off pump flow capability) and will simply return excess fuel back to the tank. Your engine will run exactly the same with the same performance/economy. Any more questions, just let me know.

So Ben, any thoughts on his reply? Sounds like a goer at first blush, with one variation to his suggestion. I'd leave the wiring harness connectors as is and make up a short adaptor lead and mating connectors to suit ... no problem. That way I can reconnect my existing fuel pump (probably original 19 yo) should the need ever arise.

You may have missed noticing the relisting is now $10 dearer .... dammit Ben, I may have to offload my toxic assets to help pay for one now.

Cheers.

Ken

Sounds like it is the wrong pump to me.

It has a higher litres per minute flow rate.

These pumps are not like electric fuel pumps for carburettors. They do not cut in and out due to pressure, they just run continuously and the pressure regulator sends the excess back to the tank. The digifant system was designed for a certain flow rate and if the fow rate is too much, can the return system handle it on overun when the injectors are shut off?

I could understand using an alternative pump if the genuine article was no longer available, but why when they are not hard to get? These exact pumps have been on Kombis since arount 1974 so they should be available for a while.

Phill,
Thanks for the detail ... interesting. Yes I often see the genuine
article 2nd hand on ebay, always wondered the sense of buying one
especially when not knowing how much life might or might not be left in
them, by all reports they can fail suddenly, hence the interest in a new
one instead, like this one I uncovered on ebay.

I'm not sure but I had the idea the genuine article is something like
$250, maybe someone knows for sure. If so, makes this one look quite
reasonable if it were to do the job satisfactorily ... a mute point.

Essentially it would work then, your main concern is the difference in
flow rates between the genuine one and this? Meaning do you know the
correct flow rate for the genuine article and compare that with this
pump?

Hi Phill and all the guys and girs I do'nt know yet
now about the pump--excess simply flows back to the tank?? He, do we have a return line to the tank? I hav'nt got one on mine(than again I could be wrong here). What's meant ,I think, is ,that the pump is holding the pressure not unlike the common rail system in a diesel engine. I will check tomorrow what sort of pump the fixer guys installed into mine, when it needed one, but I'm sure it was'nt the original, however it seems to work ok (O tto K aiser was an Inspector at GM who used to mark the crankcases with OK when they were ok) Hope to meet many of you at the weekend

Fuelflow is important but can be worked out .On my VW powered little aircraft I have to demonstrate the max fuelflow which gets recorded into the logbook. My engine delivers 8o hp max. and it uses for arguments sake 180g of fuel per hr /per hp = 14.4 kg of fuel per hr going for take off (full bore).Now 14.4kg : 0.7 = 20.5 liters of fuel .In aviatian we double that and thats what the pump has to deliver max. If it delivers slighly more , who cares, if it delivers too much, it just uses too much electrical power, thats all.
these are my thougts on this topic anyway Hartmut

The standard setup is that the pump supplies fuel to the fuel rail at a constant pressure. The injectors supply fuel to the cylinders as required, from idle to full throttle. The rail must carry enough capacity and pressure for the full bore condition, plus a bit. At idle, it need only a tiny fraction of that. The surplus fuel is returned to the tank. This detail can probably be seen in Bentleys.

When you get a new pump, it is full of some sort of liquid to stop corosion. Does anyone know what this is? If you get a s/h pump and let it dry for too long it will fail. I have a spare that was taken from a '76 Kombi and filled it with WD40 (or similar) and plugged the ends. Hopefully this will preserve it.

Any ideas on what to run through the pump to test it as in service it requires petrol for lubrication and cooling. I do not like the idea of running it with a bucket of petrol in the open air.

Phill and ALL,

I like the way this topic has developed .... not sure if fuel pumps have
had all that much of an airing here in the past.

So yes, what's been said about the need to preserve the spare 2nd hand
pump in operating condition .... not allowing it to degrade in storage
seems to have validity. I'd certainly like to know the best method in
that circumstance as well.

Also again ... whether that ebay pump ... on balance ... would still be
worth a try. What could be the worst scenario as a consequence of its
use as an economical and new alternative?

Cheers.

Just to put this in perspective, what is the price difference?

Is it for an emergency spare?

I am guessing that you are talking about new pumps.

I have my 19 year, almost 200k old fuel pump still working on the van
(assuming it's never been replaced by a previous owner, I have no idea)
and so I'd like an emergency spare, which one ends up as the spare
doesn't really matter, particularly if I can mothball the spare
correctly so it still works if I need it.

I mean it would be better to trial the new ebay one now, establish its
working ok rather than fit it later for the first time and untested in
the middle of Nowhereville.

As I said previously, I thought a new genuine pump was around $250. This
new ebay pump is around $100.

Can pumps be pulled apart and serviced? I don't mean a fried electric
motor scenario.

That's the problem, how do you mothball it?

When pumps are new, they are filled and sealed. If you use it????

These pumps should be OK to get you home and would be a good idea for a spare as long as the fit and the connections are replaced.

They are crimp sealed.

Ken,

Sorry for the later reply. These same pumps are posted on US Ebay between $49-$125. Some seller's advertise "lifetime" warranties on these puppies. That sort of sale's pitch usually makes me run as fast as I can the other direction. As far emergency use, I would guess this is a viable alternative but only after testing it first. And as others have pointed out, how do you store it then? Leaving gasoline/petrol in there will likely cause deposits which may cause the moving parts to get stuck together. You could be out in the middle of nowhere with the expectation that you have a spare pump only to discover it's locked solid.

A friend of mine has an unorthodox solution to that. He uses his 'spare pump' at least once a month for transferring fuel from a spare can to this main tank. He is essentially testing the pump ever month.

Ben,

So with what you say, all the 2nd hand vanagon fuel pumps on US ebay
that crop up fairly regularly for around $US50 or so, you reckon they
should all be avoided?

No, Ken. I meant the NEW aftermarket fuel pumps are on Ebay all the time.

Used ones are typically about the same price as new aftermarket.
