Re: [doc] Misfire Under Accelaration???......

["Mike" <mike.bosworth@xxxxxxxxxxxxxx>]

Hiya All 

Fuel pump problem now resolved......pipe had kink in it at the elbow 
just below the pump connection , hence decreased suction / 
spluttering.... and just by twisting the pump out of the tank it 
shows how easy this is to do!... hose was a new item as part of a 
DDMCH kit... but overall not impressed with the baffle / pump 
arrangement..... especially with a tank full of fuel and my arms now 
covered in a nasty petrol rash!!......now wheres the baby's nappy 
rash creame!!

Thanks again for the advice guys!

Mike
