Sure that's not just the float chamber bowl for the carb ? Is it part of the carb ? This is an SU carb - the part on the left is the float chamber (although it can be on either side) - with the top held on by 3 screws.

Any chance you can post up a picture of the fuel pump - seems a waste to spend all that cash on a fuel pump if it's not needed.

Sounds like the float chamber to me too. The air filter housing and backplate needs to be removed to get to the screw that is obscured. You will find two bolts with I think a half inch af head on them once you remove the air filter top piece. Check that the float chamber is clean and that the hole in the bottom is clear as this is the delivery to the carb for fuel. After 6 years it could well be blocked up with gunge.... Check the pump with a meter to see if you are getting power to the live terminal. If not, check the fuses and feeds from the fuse box and check for any breaks in the wiring forst. No point buying a new pump if it just needs a new fuse !!!!!

Hi, couldn't get a picture because I left my camera at a mate's house after football on Sunday but should get it back tonight and take pictures tomorrow and post up.
It is the float bowl as it's the item you mentioned and is shown in the picture.
As said I'll try the power to the pump this afternoon/evening and see if that's the problem. I did find one small red wire from the positive terminal with an in line fuse on it and as no obvious accessories such as stereo or spot lights I tried the fuse to see if it was u/s but it looked ok and may well have been for something else anyway.
I'll whizz the float bowl off (probably at weekend) and see what state it's in, meanwhile can someone tell me where the fuse is likely to be found please?
Also tempted to buy a small in-line filter as I will be replacing the fuel lines around carb anyhow and thought fitting one might be a good idea.
Looks like I have found a s/h rad for it incidentally so (time permitting) I'll collect at weekend and fit if the mew small piece of hose in front of wtare pump has arrived.
Tempted to get a new water pump, gasket for same plus thermostat and gasket and replace whilst rad out, do you think it would be worth it?

To be honest I'd get it started first before replacing anything that's likely to cost hard earned cash. They may not need replacing and like mine once the heat from the engine penetrates the gaskets they may all reseal again.

Thanks Dean. Phoned round a few places today to check availability of fuel pumps and seems order in only and there's no universal type ones available. That doesn't help me unless I can either find a suitable/similar one from another car or order an original one in.
Still plan to test the electrics first but I'll also try and take a picture of the unit currently fitted on my mobile phone and post up on here.

You might find that your pump has a different fitting for the fuel input from the SU pump. My Minor came with an aftermarket pump which had flexible pipes onto it (input & output) but the replacement SU required a screw-in solid pipe. Fortunately the supplier found me a 2nd hand fitting with a stub of solid pipe.

I'd never seen an original SU pump before that so had no idea that a previous owner had sawn off the end of the solid pipe to fit the aftermarket pump.

New SU pumps are very expensive - so dealy any purchase until you are SURE you need it. The car can quickly become a money pit - if you spend spend spend! You may well need to remove the water pump to fit the new by-pass hose - I hope you got the solid type and NOT the ghastly 'convoluted' type which is no more than a get-you-home botch up. The straight pipe is just a bit of 1/2" thick wall hose. DO NOT take the float bowl off - but you can take the top off (3 screws) - but go no further.

Thanks BMC.
Ok, removed fuel pump which says 'Fuelflo' on the bottom and certainly appears to be a solid unit. It IS getting power to it and some distinctly old and smelly looking petrol came out. Hoping thatw as the problem we tapped it a few times and tried refitting it to see what happened. Unsurprisingly naff all I'm afraid. Anyhow here is the pump...



Apologies for picture quality, taken on my old mobile and sent via bluetooth to pc.
Have decided not to meddle with the float bowl for now and the item I got from eBay is a solid rubber pipe, two inches long c/w two clips and is sort of concertina shaped in the middle if that makes sense?

Surely rubber pipe is rubber pipe BM, my gasket kit came with a corrugated effect bypass hose....cant see the problem with it??

Someone out there must be able to point Mogster at a cheap(er) solid state pump if he's not fussy about originality? "Facet" is a make I've used before on other things. Probably loads on Ebay!!

The concertina/corrugated by-pass pipes are hopeless - use it at your peril. Useful for squeezing in to place at the roadside without taking the water pump off, but definitely not 'long-lasting'.
That pump certainly not an SU - so start looking for a good second-hand one !

I wonder what that pump came from?
It looks quite modern and was probably meant to be fitted close to the petrol tank on a car with fuel injection .
Aha!

Plenty of details there.
I'm not sure how the pressure figueres compare to an SU pump but I'm sure an SU won't pump 1.5 litres in a minute more like .5
Big filter in there, might be worth soaking and rinsing with clean fresh fuel.

Can someone please post a link and/or photograph of the 'proper' piece of pipe that I need.
The one I have looks exactly the same as the one currently on the car (not that that means anything I know) but I'm sure when I looked at a MM spares place the ones they offered looked exactly the same?

Marky: I'll try cleaning it later, thanks. I wonder what pump Halfords would supply, they quoted £65 (I think), is that likely to be the same as the original?
Thanks and regards.


*Edit I'm sure the pipe I bought looks the same as item number ten on this link...

Edit edit!: This is the one I purchased...

The best pipe is simply a short length of 1/2" thick wall rubber pipe - straight with no concertina. They 'never' burst! If I can find a link I will post it up - but most just cut from a length of pipe!

Ah, thanks. Hopefully I can get some of that when I find somewhere local who supplies petrol pipe.

It's exactly the same as the heater hose.

Here tis - from ESM - this IS the one to have !!

And - here's a suitable fuel pump.

http://cgi.ebay.co.uk/SU-Fuel-pump-Morr ... 286.c0.m14

And if you look closely at the picture you'll see it has 'HEATER HOSE' printed on it...

Which is exactly what it is !!

Thanks gents. Shame about that pump bmc, spotted it a little earlier on eBay but it's a private listing and I never bid on those.
