about Electric fuel pumps this is why I really enjoy ACVWSA !
Been doing research on this topic for my engine build and want to go with an electric
fuel pump setup on a 1600TP type 1 motor with twin 36idf Webers, also going to be using
a G Tech electronic ignition system.
I spoke to the guys at Huco in Boksburg and was told the Huco 133010 has been discontinued
and the two options are the 443000 (Tank placement) and 443010 (Engine bay placement)
But reading here believe these are no good !
I see the other option is the Facet 40163 .... where can I get one of these ? Considering all
the drama at the moment don't want to try import anything and would prefer to walk into a
shop and get one ... ( not sure if this is wishful thinking )
Beside the above options are there any other options ....? what solution does Volkspares in Jet
Park offer ... ?
I use and sell a pump that works perfectly for the weber IDFs without a pressure regulator. I've been using them for years on my own rides and selling them to others. It is also pretty damn quiet.
I also have the Gtech and new Bosch coils in stock.

I'll only use a fuel pressure regulator as a last resort. More plumbing in the engine bay introduces more connections and clamps that could fail, increasing the risk of fire.

There are many , many Huco pumps, the only way you will know if you have the right one is the part number.

Know the local agent carry Huco pumps, but has never carried the correct one for VW in the past,

Will be nice to know which one he sold to you.

I purchased two of the 44 3010's...tested the output pressure and it was just over 2 PSI on our guage. It also has an auto cut-off so that - when it feels back-pressure from a full float chamber / closed needle and seat - it automatically switches off. Used them in my 1275 GTS Mini, now on my Kombi too. My facet pump was pushing out over 4 PSI and was just no good.

Interestingly enough, when I check Diesel-Electric's website they give the spec as 0.3 bar (4 PSI) for the 443010 (same as the 443020 so why have different models, and the 443020 is supposedly high pressure whereas the 443010 is not marked as such).

However we have tested the 443010 and it definitely gives out just over 2PSI... an eBAY advert for the 443010 also specs it at 2.2PSI so I trust eBay :)

Hope that helps...

The Huco pumps have 2 same pressure pumps with near the same model numbers,

The pump is the same pressure but the one will be near tank mounted and the other near motor mounted,

In other words, the one is suck pump and the other is a push pump.

The Huco 44 3010 is the near to motor pump, and the 44 3020 is the near tank pump

Both are rated by Huco as 0.3 bar pumps. Have a look at the spec sheet that came with the pump it will state all the info.

Hope that clears up the Huco number system.

Thanks Herman; so I checked out the specs online (the pump doesn't come with a spec sheet just an installation guide unfortunately) and you are correct in your statement. The diesel-electric website spec sheet says 0.3 BAR (4.3PSI) for both including my 443010 which should be way too much. I've installed the 443010 pump closest to the carb and just tested the pump pressure again...it is 2.2 PSI according to my trusty and (relatively) accurate gauge...so I don't know whether my pump is under pressurising or the spec sheet is wrong.

However the fuel path is clear, and I removed the filter before I tested...so go figure...my gut feel tells me the diesel-electric website is wrong and that the in-engine-bay pump is 2.1PSI (European model HUCOPUMPFP02) and the tank-located pump is 4PSI (European model HUCOPUMPFP03)...this is what the European websites show to be the case. However the irritating thing is that the carb model numbers differ in Europe from ours here in SA, and to top it all different European websites show the same model with different output pressures!!!

Maybe your buddy can shed light...

2.1PSI - engine bay end https://classiccarbs.co.uk/product/huco ... in-germany
3.9PSI - tank end https://classiccarbs.co.uk/product/huco ... de-germany
2.1PSI - tank end same model different type number https://www.dellortoshop.com/contents/e ... _Type.html
Article on eBAY which says the 443010 and 133010 are the same spec https://www.ebay.com/itm/GENUINE-HUCO-1 ... 4658960028

TOTALLY CONFUSING!!!

Evan,
Based on your experience with the HUCO 44 3010, it seems like a proper pump for our air-cooleds is available locally in South Africa.

Evan , I too looked around and got confused so i did the right thing.

The only reliable specifications would come from the manufacturer and that is what I see as gospel.

They say that the only under 2.1 psi pump is the 133010

Now Maybe the pump gives different pressures on tank height, or sea level, or pipe size, I do not know

But what I know is that Mark from KZN fitted that pump and it keeps flooding and or pushing his fuel usage through the roof.

Have tested mine and it runs anything from 1.8 PSI to 2.0 PSI but has never gone over the max given by the spec.

If the spec said the pump should be below 2.1 PSI why is your pump giving 2.2 PSI ?

The manufacturer will not have the same pump under 20 different numbers, this makes no sense.

OMO

Ok...thanks Herman...that all makes sense...I'll email Diesel-Electric and see what they have to say...

As for the pump pressure, my gauge is about 65 years old...so it is very possible that it overreads a bit...it was my uncles for years and I got it when he passed on...my carb mechanic buddy also has an old PSI gauge and his showed just under 2.1PSI so that seems the issue.

But that is a far cry from 3.9 PSI...

AS for my carb, it's working like a dream...no flooding at all...

Sounds promising. I'd still like to know why MARK had such a bad experience with this pump.

I just need one more person to buy the HUCO 4433010 pump from Diesel Electric and confirm the 2.1 max pressure reading, then I'll bite the bullet and get one.
