Thank you for the reply..... That sounds good as I live in Durban South Africa and the temp is around 30C+ at the moment.

I have a W124 230E and it runs fine except when I start after stopping for say an hour. It takes about 3 or 4 attempts to start - which causes anxiety to all including me!

I will check the fuel line in case its too close to the engine. Should I get the fuel pump serviced? I have also heard that a filler cap that is not breathing properly can cause a problem.
