Fuel filter housing Nissan Patrol - manual prime - Fault

Greetings guys -- ran a few keywords in the find -- nothing comes up - though i remember maybe 1 year ago this may have been discussed .... anyway


My nissan has been playing up --- 1 st gear - runs through the revs fine past turbo kick in point --- upto to 3k rpm easy --- 2nd 2 k rpm struggles at Turbo

3rd -- does not make turbo easy -- has to wind up slowly without putting foot to much into it .... fuel starvation ......

I check the little inline filter i have after the main z332 fuel filter ( its a sight glass type ) and can see fuel intermittently going in and through -- not even filling the glass when running .... push the Prime button a number of times - can hear a air sucking sound ..... - take fuel inlet to filter block off -- pump primer -- hardly no suction at all ( to none ) so its leaking air / sucking air

put inlet fuel line direct to my inline filter - ( bypass main filter ) took for a run -- fully loaded each gear -- runs perfect ......

Now that i have worked out the process of elimination ( may help others in the future ) My question is - is this an after market part - can i get from repco/arb or other such places or is this nissan specific ?

thanks
