Re: SU fuel pump mark 1
Hi, will this help?
The pump is held in a circular clamp which is then bolted to the top plate of the left pannier.
Cheers
Chris

The top? Could you show me a photo? Just doing this job now....no holes in top of pannier box, but the bracket seems to want there, except for sliding pants over bolts each time getting in.

Hi Peter,
This what you are after? Front of the Moke is to the left
Front fixing hole for the pump is approx. 95mm inboard of the fixings for the hand hold (and 65mm from the inner edge of the side pod) and is 65mm behind the front fixing for the hand hold.
Does this help?
Cheers

Re: SU fuel pump mark 1
Yes, Chris, that does help. However, mine is RHD, so there is no hand grab handle on that side.
I will just locate the mounting holes close to where it looks like they want to be. Actually, I was really looking for a photo similar to the workbook drawing, with the side cover off, looking in at that darn fuel pump, and all the fittings.
Are there two metal lines after the pump? I know there is a short petroflex line, then a twisty metal line, and perhaps then the long petroflex line, but I am not sure on that. ........
Now I have to refurbish the tank, a task I have been putting off, but I now don't think it will be too bad, just time consuming.

Re: SU fuel pump mark 1
Yes, you are very helpful! I do appreciate your efforts! Thanks again.
As a follow-up, the fuel lines forward of the pump - first, a short flex line, then a metal....does that metal line carry on through the pannier side and firewall? Then flex to carb?
Thanks again!

Hi Peter,
From the pump, the copper pipe goes uder the front wing,
Then into the Moke interior,
Then through the bulkhead into the engine bay, then flex to the carb.
Cheers

Chris, is that a fuel filter in the inlet side of the Pump?
While it may seem a good idea, it's actually not wise. When the filter blocks up, it will actually allow the pump to stall in an energised state and in doing so, will burn it out, it is also the common cause of the points burning out (in the non electronic models).
OK, sorry for that, resume topic

Hi Spider,
Thanks for the advice, I hadn't noticed it before Peter asked for a photo of the pump! If the filter is on the delivery side of the pump i.e. just before the carb where I have seen them on other Mokes, would it not have the same effect if it blocked up? Perhaps I ought to change mine to this location.
Cheers
Chris

No, it doesn't have the same effect. Think about how the float bowl / needle and seat works. The fuel flow is reduced and shut off at times. That's normal operation. Putting the filter in here, has the same effect from the pump's view. It just builds up pressure, which is what shuts off the pump and then waits for a pressure drop before starting to pump again.
If the inlet of the pump gets blocked up, when the pressure on the outlet drops, which could be because there's no fuel flowing through the pump, the pump will try to suck and push more fuel through. If it does get some but not a full load of fuel, the pump won't reach full stroke (hydraulic lock) and so won't trip the points to turn it off, leading to a burn out in fairly short order.
On mechanical pumps, this isn't an issue, there's nothing to burn out, but not so on SU electric ones (and I think most others).
