Diesel low pressure problems in Accent Crdi

I have an Accent Prime Diesel 2005, something similar happened to me .. in reaity it happens to me ... and I asked in a workshop and wanted to extort myself ... I know some mechanics and it was not necessary The tip carries a microfilter .. take out that piece and torch with precion or mandela air to clean with ultrasound where they repair pumps ... with that the problem will be solved ..
