hey all
let me jump on board as well!
every cars fuel tanks collect crap - thats thanks to the shite
overpriced fuel we get plus crap inside filler necks and fuel caps,
fact of life,
almost every car ive worked on (on thats a few!) the insides of the
tanks are dirty. Thats why we have fuel filters, obviously to save
this crap going to places where it shouldnt.
Generally on most fuel injected cars a filter can be located before
the fuel pump if external, and that is the best idea by far.
Unfortunately we are blessed with an internal pump to collect the
crap, and next in line is mr accumulator before we see mrs filter.
Bad bad bad news
Mr accumulator is a innocent man walking along past a group of women
throwing crap out of a window
morale is i suppose clean yer tanks! look after mr accumulator and
give mrs filter the boot every year!
yeh baby!
