Club 80-90 Forums

Hello, during the hot weather when I go to start the van first thing it can take anything from 10- 30 seconds to fire up as though the petrol is slowly making its way up from the tank. Yesterday it felt more like a minute.
This is with the usual one press of the accelerator then not touching it again and it will fire a run on choke.
Once it has been started it will run, stop then start again as usual.
Fuel lines are new, filter new, pump about a year old, push rod ok so is it worth fitting a pierburg non return valve before the pump. Nothing to lose or complicating matters??
I know they say the pump is a non return valve but this only happens when it’s been stood for a day or two in the hot sun. In the Winter it fires up straight away.

Have you checked the small filter in the pierburgs petrol entry pipe ?

Yes, it’s all good.

Cooler and drizzly earlier this morning and fired up straight away after being left a day.
The valve can stay in my spares box.
I’ll probably fit a new pump/ rod if it continues and see what happens rather than introducing something else into the mix.
