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



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
