Did a Google search on “VW = Jetta fuel system”.  Here is a cut-n-paste from the very first hit. 

1985 Volkswagen Jetta NHTSA = Recall ID Number: 87V053000

Recall = Date: APR 14, 1987
Component: FUEL = SYSTEM, GASOLINE:DELIVERY:FUEL PUMP
Potential Units = Affected: 278520
Summary: = FUEL PUMP, LOCATED INSIDE FUEL TANK, COULD SEIZE = DURING HIGH AMBIENT TEMPERATURES BECAUSE OF AN EXTREME FINE MESH FUEL = FILTER RESTRICTING THE FUEL FLOW.
Consequence: FUEL = SUPPLY TO ENGINE WOULD BE PARTIALLY INTERRUPTED,RESULTING IN = STALLING.
Remedy: INSTALL A = MODIFIED FUEL PUMP AND FILTER.
Notes: VOLKSWAGEN OF AMERICA,INC,
