Drove it home tonight after servicing it and it puffed (now a solid stream, just a few puffs) when on boost around 2300rpm. Seemed more than normal, but then it hasn't been driven in nearly 2 weeks.
My question is what could this seemingly random puffs be? Is it more likely to be pump or injectors? how can you check if there is a problem with the pump or the injectors? Any sort of troubleshooting possible? Am hoping the lines fix the leak as I don't want to have to get the pump reconditioned.
Motor was rebuild 2yrs ago and pump was bench tested at the same time apparently (previous owner's receipts) and a dial guage was thrown on it only recently to check it was dialled in.
