Got the 80 MOT'd yesterday morning, ran round in it all day enjoying the sunshine Only hicup was pulling up a steep hill in 4th overdrive - as it got steeper the 80 started to cough a bit like its running out of fuel or the igntion is cutting out. Ease off the throttle and change down to 4th and it pulls up the hill. Try and use full throttle it starts coughing. Once on the flat I can put my foot down and it goes like a train. Just not in a high gear under a heavy load like on a hill.
Went out in it today and along a flat bit of road it started to cough like it was running out of fuel. Sure enough it cut out and I coasted to a halt. Looked in the tank and it was low. Rang my wife and she brought be a jerry can of fuel which I put in. It won't start and the fuel pump isn't ticking. Pull the fuel lines off and suck fuel through to the carb but the pump won't go. Resigned to being towed home when the pump bursts into life. Still won't start, so I wonder if there's rubbish in the carb. Eventualy I nearly give up when one last press of the starter button and it fires up!
Drive home no problem. Park on the drive turn it off. Then try and start it and ... nothing, no pump. Decide to watch the gand prix and have a look later. Turn the ignition on and tada! Pump work and it starts. I'm wondering if the pump is getting hot and breaking down?
For those who don't know its a 2.5 petrol with a Weber 32 34 dmtl and the pump is a normal SU
This is a long way of saying that I guess the pump is on its way out Could this explain the coughing under load (not getting enough fuel?) Would an SU deliver enough fuel for a Weber 32 34? If not does anyone recommend one? and, I've not serviced the carb (prefered to run it and see first), can you service them and is it worth it?
I'm thinking of getting a facet pump. Should the carb have a return feed to the tank? At the moment there's only what looks like a overflow pipe.
At least I got home under my own steam and didn't turn up being towed in front of the neighbours
