peterc Posted July 15 Report Share Posted July 15 Hi, I'm new here, so apologies if this question has been asked a zillion times before. I struggle to restart my newly aquired Vitesse from hot, after a run. I can see fuel boiling in the glass topped filter. There seems to plenty of air around the filter, so I'm guessing the filter is conduction heat from the block, to which it is bolted. I wonder if it is possible to fit an insulation spacer between the block and the filter of say 5 or 6mm thickness to lessen the heat transfer? If I did this, is the pump lever long enough to stil engage with the cam? Thanks for reading. peterc Link to comment Share on other sites More sharing options...
Steve P Posted July 15 Report Share Posted July 15 The more space between the pump and block, the less pressure. Is it standard as far as carbs and exhaust manifold?. Shouldn`t be boiling. S Link to comment Share on other sites More sharing options...
johny Posted July 15 Report Share Posted July 15 Are you sure air isnt being pulled in the fuel line somewhere and bubbling in the filter? Feel the temperature of the pump when it happens - just too hot to hold is about 60 degrees and that could start boiling.... Link to comment Share on other sites More sharing options...

Is it fresh air getting in, or just the bubbles on top being agitated by the pump action? You'll never get them all out, but if it's excessive bubbles then there may be a leak somewhere..

Pete Lewis Posted July 15 Report Share Posted July 15 first thing to check is the short fuel hose from the top of the tank/reserve outlet tomthe pipe work this little gem is hidden up in the boot its so common this goes hard /ignored and sucks air but wont leak fuel as its above the tank fuel level fuel in the pump is air bubbles its never boiling .... i feel that idea is bum steer Pete Link to comment Share on other sites More sharing options...
68vitesse Posted July 15 Report Share Posted July 15 Had one of the glass filters just after the tank in my MK1 2L Vitesse for years with no problem, when I fitted some gates barricade flexible hoses moved the filter to just before the carburetors and had hot restarting problems. Moved filter back to just after he tank and problem went away, find l do need quite a bit of throttle when hot restarting. Regards Paul. Link to comment Share on other sites More sharing options...
peterc Posted July 16 Author Report Share Posted July 16 Hi, thanks for the feedback. I'll check for air leaks, particularly the rubber pipe near the tank as mentioned. Link to comment Share on other sites More sharing options...
