[alfa] Re: GTV6 fuel pump/filter orientation

[Shures <shures@xxxxxxxxxxxx>]

Every GTV-6 I have seen has this set-up.  
1) Every fuel injected car I have worked on has a large filter after the 
pump.  
2) Someone from the digest offered one of the U shaped hoses for sale 
last year.  I thought about buying it just because my fuel pump seems to 
have a bad check valve and hoses might be part of any repair attempt. 
But I didn't.

I always thought I could work something out with Earl's or Aeroquip 
fittings; they have U shaped fittings.  There seems to be room to make 
some gentle turns under there without the use of any special hoses or 
fittings. Anyway, my pump still works so that project can wait for 
another day.

What are others doing when faced with a pump problem and old hoses?

By the way, the fellows at Centerline near you have been a good source 
of GTV-6 parts and advice.  I shop as close to home as possible but have 
sourced some things from them and gotten very good, sensible advice.
