[Mgs] Intermittent Fuel Starvation

Sat Apr 29 11:54:26 MDT 2017

I researched this subject on the MG Experience site.  Found a couple of 
posts wherein the problem was cured by replacing the fuel hoses from the 
under-hood inline fuel filter to the carbs. Diagnosis was that the 
needles were glued to the seats by fine rubber particles.  I sent a PM 
to one guy asking him if he'd had a recurrence of the problem after he 
changed the fuel hoses.  He replied, said no recurrences.

So I replaced the fuel hoses with new bulk 1/4" hoses.   I have some 
OEM-type braid-covered hoses coming from LB Car Co.  So now the fuel 
filter & hoses are new.  We shall see ......
