Re: [alfa] GTV6 fuel pump/filter orientation

[Steve A <gtv2000@xxxxxxx>]

Wanted to thank all that replied off digest.  To summarize for anyone using 
search -

 All agreed that my described configuration was original.  The explanation 
for the filter following the pump is that the pump internals are immersed 
in the gasoline for cooling, therefore any wear products from the pump 
brushes need to be filtered.  It was explained that molded hoses were 
original equipment, so that kinking wasn't a problem.  These are no longer 
available.  It was suggested that an after-market filter could be added 
between the tank and the pump to save the pump if the sock filter in the 
pump has rotted away, which is likely after these years.

No one could explain why the parts are not oriented differently as to make 
hose routing simpler, other than it's Italian.

Thanks to all,

Steve
