what engine?
D15b3 carburetor engine
blow out the feed and return lines with compressed air, change the fuel filter and check the fuel return flow from the pump, it should be constant and not foam up when the engine gets hot.
in my case(charade) used(kabli) mechanic pump works alot better then new chines toys...
other option is to repair your original mechanical pump by getting new fuel pump repairing kit from market..
one thing return pipe was changed because old pipe was hard and brokentoday i will blow out air in pipes where is fuel filter located as i don't see any filter type thing in bonnet .
the filter is mounted outside the fuel tank, its reached from under the car.

raise the car and replace it yourself, it requires a 10mm thin socket and a small screwdriver.
