Mokes have a fuel line that runs up from the tank to above the engine-bay cross member then down to the mechanical fuel pump.

I have tried to replace the mechanical pump with an electric but there are two issues.

1) there is no suitable place to put the pump and,
2) the pump has to draw fuel up from the tank to prime.

My attempt ended in an engine-bay mounted Facet which couldn't prime itself and gets hot and suffers vaporisation when the trying to hot start. I sorted the vaporisation with insulation and foil heat shielding but that looks mega ugly. I sort of fixed the priming issue by changing the spring inside the Facet. The car is missing badly under load so fuel starvation is a possibility I'm trying to eliminate.

To fix this mess, I want to put an in-tank pump in the car. I already have a custom tank so the question is:

What is the best, sensible-cost in-tank fuel pump to get?

I expect there are many carby cars that have in-tank pumps that have only one fuel line and don't need a regulator. Can anyone suggest a suitable one? Has anyone been down this road before?

If I don't get any advice I'll go through the Pierburg catalogue and try to pick one from a common car or one that has a suitable rate & pressure. The only reason I hadn't done this already is that there are no prices in the catalogue so I haven't got a clue which is the best priced, nor which are available in Aus.

Advice anyone?? Any other location for the out-of tank pump that doesn't involve cutting the body up? Note that my car is an 82 and the tank takes up the whole side pannier, no room in there.

I have an electric pump in the sidebox in front of the fuel tank. It pokes through a hole in the dividing panel between the sidebox internal area through to the tank behind it.

No idea what brand/model it is - it's a BIAM mod. Works fine where/as is.

You can get low pressure intank pumps.
The 'tiker' pumps, as I call them, work better back at the tank. Move the one you have, put it on rubber mounts under the back near the outlet, they're water/muck proof so that won't matter

I have an elec pump (square boxy type) up near the radiator overflow tank,
no over heating or priming issues.
it's mounted on a couple of small rubber cotton real mounts to lessen the noise

A couple of options maybe, mount it in the bottom of side box so it should self prime
or get a one way valve to stop fuel syphoning back to the tank.

I've got the pump mounted on the firewall- LH side

Facet fuel pump, in the passenger side box on 2 cotton reel mounts no problems, quiet and works very well to fuel a 45 weber...

Check your tank for internal Rust and flaking. We had a problem of the sort with a friends Moke. Might have to take tank out and clean it out. A filter will also help. The pick up pipe in the tank might be clogged too. Give it a blow back with Compressed air and make sure tank cap is off.

Hey Mokesta,
I see a number of the replies suggest the side box, but your Moke is later model so no space at all in the left box right?
I have older Mokes so where does your fuel pipe exit the side box?
It may be excessive but what about getting steel (Bundy?) tubing and running it back to the rear subframe (common on Mini) and then forward again? This would remove the priming issue, heating problem and also reduce the 'cabin' noise. Just means a longer flow travel, hey an extra 50ml fuel in the line

Cheerio
Chris

Cool stuff!!

Yep, it's the last of the Aussie Mokes (very close to it being 1982 compliance) and had a cylindrical tank that took up the whole side pannier. No room in there for a pump. EDIT actually, it may fit a small one in the top corner...
See here: (fish oil not rust)



Now it has this tank, which in the photo has been fitted with the pipe from the old tank that coils around so that fuel vapours condense. That goes to the charcoal canister:



As you can see both tanks have their outlets at the top and the fuel line runs out the top corner of the compartment, into the passenger space behind a trim piece then into the engine bay right above the passenger side suspension tower. I have my fuel pump adjacent to the radiator expansion tank:

It and the fuel line are now covered in insulating foam and foil to stop the exhaust heat from cooking them.


Keen observers will note that the new tank has a huge hole in it. This is for fitting an in-tank EFI pump for my EFI project. Since that project was a fail due to my fabrication skills, I may use my cross-flow head on the moke and make it EFI. The 850's engine is a LONG way off anyway.
