Mk2 8v on Bike Carbs, annoying problem.

Potentially stupid question: Do you mean physically bypass with some fuel hose, or just pull the plug on it?

i didnt spot you still have the main pump there, if so no wonder its playing up! that baby pumps out 5bar of pressure and 128litres an hour!

if it was me i would remove the main pump and fit your bike pump where it used to be. to do this i would find a mk3 golf fuel filter bracket, strap the bike pump to that on 1 side, and use a mk1 fuel reservoir on the other side to help prevent fuel starvation.

edit: like this, but with a bike pump rather than a k-jet inline pump:

I'd also change the plastic fuel lines for mk3 golf ones so you can use all push fit pipework rather than messing with threaded fittings

OK, I tried pulling the plug on the main pump and still exactly the same thing. I then pulled the plug on the lift pump too, and still no joy.....

Anyway, just as I was about to start raging my Dizzy cap and HT leads arrived. Threw them on, reconnected the pump plugs and she fired straight up. 5 minutes later it's still running, so I decide to venture up the road, still running and driving sweet as a nut 

Looks like it was the dizzy cap or HT leads all along. I'll still eliminate the main pump but for now it's running, and running nicely.

Thanks for all the help people

just goes to show, try the cheap and easy things before you get too in depth
