Hi, my 1600 coupe has not been started for at least a 2 years i have got it running by putting fuel in the carb but the fuel is not getting there from the pump.i have manged to suck the fuel into the filter but will pump from there

Thanks Shaun

Hi Shaun,
Your pump internal diaphram may have perished,causing only a partial flow.
The could be a blockage between the tank and the pump.
A hose may have internal damage that you can't see.
The fuel tank sender unit has a gauze filter which may be blocked.

I would start at the tank. Remove the sender unit [the fuel comes up through this] and check for crud
in the tank and on the gauze. Then try blowing through the pipe to the front. If that all seems good,then reconnect everything
, but have the pump outlet drain into a suitable bottle [disconnect the coil lead right now] and try spinning the engine to fill the bottle.
You really need to do this so as to drain all the 2 year old fuel. Unless you've done that already of course! If the pump isn't
gushing lots of fuel,fit a new one.
Hope this helps a little bit.
Regards, Nigel

Thanks Nigel, i was thinking of putting a electric pump in any ideals?

Plenty of threads on electric pumps in the carb section of the Forum.

As Neil has suggested,read those columns.
I fitted my new pump today coincidentally. It's a Huko,together with an inertia switch [random,ebay]

Thanks guys, is this  wiring setup ok

That will work fine

Just about to swap out a (failed) mechanical fuel pump for electric and working through relays, wire colours, cut off valves as per above diagram. Big fan of simplicity so I came up with this

• still energised when coil is on (so ignition on)
• main feed from alternator and not starter (shorter cable length)
• no need to connect to oil pressure

I trust the earlier diagram from Shaun, but I'm struggling to see why a switched feed based on oil pressure adds value. So before I get the soldering iron out, what have I missed?

BTW yes, I have inertia switch so I can cut the pump in case of accident!

One last q. There is a natural position for the pump by the coil, but ever fearful of vapour / leaks next to the HT I aim to move it further away. Does the pump (huco suction under bonnet pump) need to be mounted vertically or can I introduce a 30 degree slop off the vertical?
