I'm putting in an extra filter, as the tank ma still have a little residue in after years of standing, even after flushing. Is it ok to mount this between the fuel pump and the carb, or does it need to be the tank-side of the pump?? ... or doesnt it matter?

Any advice gratefully received Smile

Mine is between the tank and pump. I don't suppose it really matters where you put it.

If it is an electric pump put it after as if it blocks the pump will stop pumping. A mechanical pump will keep going so put it before.

Ok, mine's a mechanical pump, so that should be alright.

There was a discussion about fuel tank filters on the Morris Register forum a couple of months ago; In the 30í and 40ís Morris apparently fitted filters on the tank pick up pipe as standard, (these filters look very similar to modern conical mesh filters found in spray gun pick ups). They appear to do their job ok for the first 40 years and then clog up (probably more to do with tank corroding! Very Happy )

The trouble is people didnít realise they were fitted and then had fuel supply problems, the consensus was to remove them and if reqyuired fit an external filter before the electric pump.

If dirt or rust scale etc. get in any pump they can cause the pump valves to leak. Surely the obvious place is between tank and pump which will protect both pump and carb.? Also obvious is to fit one with a visible filter so that dirt accumulation can be seen without dismantling.
I see no point for discussion here!

I agree Jim. I knew my A35 had one fitted under the passenger's floor when I bought it. But it was on a trip southwards that it failed and the car broke down with blocked carb jets. I fitted a new one when I got back, £1.75 from a motor factor and 5 minutes to change, and I haven't had any problems with it since. Hopefully it should be up to the next long journey!
