Hey guys!
Recently I bought a 2nd gen 4runner with the 1kz-t engine, so mechanical fuel pump. I will also post something to introsuce myself and show the car later on. For now, i have a small problem.
I noticed that it was leaking diesel, and when i took a closer look, i saw that it was leaking from the injector pump. Fuel was dripping out of a crack in the fuel cut solenoid cover, so i thought that it was leaking out of the solenoids seal. But when i took a closer look, i saw that it was dripping on the cover from above, it seems out of the "screw" that's above it. When i look at the exploded views of the pump, this "screw" happens to be the "dash pot". This dampens the fuel pressure right? My question is: did any of you guys run into the same problem with this pump? Tomorrow i'm gonna take out this dash pot. There's a gasket behind it which i want to inspect. Lookin forward to hear your opinions on it! Thx in advance guys! (See pics below for the exploded views and a pic of the leak)
