Fuel tank,pump query and emission delete etc.

[Nigel]

I'm going to clean out the tank with mercuric acid
as best as possible, blank off the
top 4 outlets,and remove all the extra pipes that go up to the red manifold. (emission system delete)
I will fit a new filter in the original position. The original measures about 74mm diameter by about 106mm long.
Is this a standard IE filter on my car?
I'm inclined to fit a new pump at the front,together with another filter.
This I've read should now be a pull type rather than push. Perhaps someone can confirm my thoughts and recommend
a pump.

Hi Nigel,

it looks like satisfying work. I've just done my fuel system and bought a ( Bosch fuel pump 0 580 464 070 ) its similar to the original one.
Some of the members might be able to recommend a better option.

Good luck, and please post a few more pic's of progress.

Best Andrew

Thanks for the comments Andrew. Yes,i'm enjoying the project so far!

One of my questions fell into the category "why did I ask that?"...... i.e. the fuel pump! I refered to a recent post for all the answers!

I've ordered a Huco 133010 for 45 quid,should arrive before the weekend I hope.
This new pump will go engine end.
I popped into a local factors this afternoon and found a Wix metal inline filter which will,
very convienently,fit into the ,now unused, old pump bracket at the rear, along with some new
8mm gates fuel hose.
As the outlet from the tank is 13mm I will probably make up a reducer in copper to bring it down to
the 8mm on the rest of the system.

I've now blanked off all the tank pipes,de-rusted the outside-top of the tank,and poured in a 3 to 1 mix
of brick acid [15 litres]which i'm expecting to take a while,with regular turning to get to each part of the inside.
Depending on the result, I may well do it again,either with the same stuff or something stronger.

So, with the metal filter at the back, I'll fit a 'normal-for-carb' plastic jobby at the front between pump and carb.

I'l also be installing an inertia switch,as it seems a really good and safe thing to do. Thanks Kevo and Eric for noting that.

To mangocrazy and betaveloce, did you guys retain the return-to-tank option?

Much regards
Nigel

Hi Nigel,

No, I blanked off the return line. I suspect electric fuel pumps are smart enough to stop pumping when sufficient resistance builds up, whereas mechanical pumps just pump away regardless.

Yes, I retained it, because at the time, I didn't really see why not

[Nigel]

Thanks for your replies chaps!

I'm now undecided but i'll figure one way or another when I get nearer
to fitting the pump. Space is an issue on my particular car as it has a black plastic tank thingy
mounted to the back of the power steering reservoir bracket. I'm not sure what this tank does yet,
it's either to do with air-con or emissions.
If emissions,it will be deleted, if air-com it may have to be relocated.

Cheers all,for now.Updates to follow.

Hi all,
An update to the above and 2 questions:

I fitted the Huco pump in the right side inner wing and all was good for a short while until it stopped working.
I removed and bench-tested it, still not working. So, having had success with a cube Facet in South Africa, I ordered and fitted
this replacement. It works fine but is very noisy,unlike my previous experience.

In the meantime, I got sent a replacement Huco which has been sitting on the shelf. I'm now inclined
to have another go with the Huco.......previously I installed it horizontally, but is a vertical position
considered better? if so,which way up?

2nd query: Is the tank meant to be open to atmospheric pressure,or is best not? At present,it builds a small
amount of pressure,relieved by releasing the fuel cap.

Thanks
Nigel

Hi Nigel

There should be some sort of vent to allow equalising pressures I would have thought. This varies according to countries, with Oz being one which from the parts book I have seen which has a different to normal one. The venting normally has an anti roll over spill protection.

Peter

[Nigel]

Peter, good advice,thanks. I seem to recall always a whoosh when removing the fuel cap on my previous HPE,
 [and was the whoosh positive or negative? I've no idea.]

I'm sure someone will advise on the pump orientation soon.

Best, Nigel

[mangocrazy]

My Huco pump (as best I can remember) is mounted vertically - i.e. the mounting bracket is horizontal. But the car is in France, I'm in Sheffield and due to Covid I haven't seen it since last October...

[Nigel]

Thanks Graham.
I was supposed to be in France round about now...ho hum! Car missing you?

As best you recall, i'm guessing the fuel connections are at the bottom,not top?

Unless someone pops along saying otherwise,i'll probably try this at the weekend.

Cheers
Nigel

[JohnFol]

Any reason for fuel connectors at bottom?

[mangocrazy]

My fuel connections were on the top, for ease of fitting. I doubt the car will recognise me when I return...  We're planning to return mid-September, even if it does mean we have to quarantine for 14 days on the way out and the way back.

[Nigel]

Any reason for fuel connectors at bottom?

John, after mulling over it I don't think it matters. In my case, the fuel lines feeding the Facet
are already down low. Plumbing will be slightly easier if I do it this way.
I'll like making another bracket. [a bad obsession? sorry,poor ref to Project Binky]

Graham, thanks as well.

[mangocrazy]

Hi Nigel, with reports of Huco pumps failing and Chinese copies in circulation, I thought it wise to buy a spare as insurance. I bought it (as I did the first one, and also my DCOE 45s many year ago) from Fast Road Cars. It arrived this morning and with it came a handwritten note - 'Mount upright with fuel unions on top'. This does sound like the voice of experience...

[Nigel]

Ah ok. That info I trust!

So,it shall be as note says.

Many thanks Graham.

[Nigel]

Update:
After hearing about chinese copies, I realised that that is probably what I mistakenly bought, it's branded Osias.
Going back to the original ebay ad, it became fairly obvious by the wording.

So I ordered a genuine Huco from Fast Road Cars and it arrived today.
And, inside a handwritten note from Anthony......exactly what yours said Graham!!

I've now got 2 spare fuel pumps, I like that. Unless of course someone would like a genuine Facet cube pump,with 8mm hose fittings
and an inline filter,make me an offer.

I'll fit the new pump over this coming weekend and post a pic or two of the installation.

Cheers.

[mangocrazy]

Excellent stuff. It did cross my mind that you might have bought a Chinese copy.All my dealings with Anthony have been first class - very helpful and knowledgeable, and very quick on despatch. I will (at long last) be seeing my Beta for the first time in nearly a year in September, so will need to verify that I've mounted the pump as recommended. I'm pretty sure I have, but memory can play tricks. I also need to wire in a relay and inertia cut-out for the pump.

[Nigel]

It's now mounted! Along with a relay and inertia switch. Power
comes from the 12v side of the ballast resistor.
I've connected the return fuel line for now,that can remain an option to plug later
if there's any issues.

[mangocrazy]

Nice work, Nigel! I'm intending to use the 12V side of the ballast resistor as the switched power source, as well. I found out through personal experience that using the coil take off doesn't work well, as it only puts out about 7 or 8V, which is not really enough to persuade the pump to get out of bed. Have you given it a spin yet?
