    ARB,
    How did you know those were the ones that needed replacement? And how did you know that those part numbers are for your specific application? I am presuming you have the old mechanical style in line injection pump where other shops have the habit of changing only certain parts to have a lower quote but do not know that other parts are vital to each other also.

    para bang man and wife........

    san province ka?

    its for a fuso 8dc81a engine, inline. OEM was zexel p49. replacement of Denso was 461-0. symptoms was, no idle, and if I adjust ang idle it would go wild. When we pulled out the plunger and barrel it was heavily worn out it had already streaks. had tried to have it adjusted first but ayaw talaga mag idle. did not change the delivery vavle as there was no stock here and it was ok pa naman. now one click na ang truck and idles well.

    Neg. occ.

    did you take out the injection pump while doing? who gave you the replacement of Denso as 461-0? so after replacing the plunger and barrel, did you calibrate the pump?

    yep we removed the pump from the truck, had it ride the calibration machine and it cannot hold idling pressure to the nozzle at 200 rpm. from a auto supply here, yep after replacing calibrated it again.

    also pwede pa discuss na rin which replacement parts to avoid and the cheaper but reliable alternative brands to buy

Medyo malakas siya sa diesel. Around 4 lng siya city driving lng. Have failed emmission tests na rin for last 2 years. 46,000 kms na siya. Am planning palang pero would more or less like to know costs. TY

    46K palang? 2000 model siya bago pa unit mo and super low milage. 2 years na bumagsak sa emission? akala ko pa naman very durable ang 4m40 natin
