Fuel / power problem

Hi all , not sure if I updated you all on the problem I was having - intermittent power loss etc , after much trial n error & investigation it turned out there was some sort of blockage in the filter housing / hand primer . Long story short I bypassed the filter with a Ryco steel body inline filter & eliminated the problem for a month , plumbed it back to standard - with yet another new filter & the problem started again straight away , wanted to pull primer housing apart but it's pressed together . I just took it off & blew it out with the compressor, didn't notice anything come out but hasn't missed a beat in 2 months 👍🏼👍🏼
