1HZ IP fuel leak...

[erics]

Just noticed a drip coming off the right rear of my 1HZ injection pump while running... coming off the large bolt that secures plate on rear of pump to mounting bracket attached to block. I can't see or feel any leaks from the connections between injector lines and the nozzle/valves they attach to, or from around fuel screw, or from top, bottom, or R/L sides... almost seems as if it is coming from behind that plate... the pump was completely rebuilt by Portland folks within a year or so. No ACSD or other extras, and they blocked off the stock speedo port on the right side. I remember it has always been maybe moist/weepy in this area, but now dripping.

Any thoughts on what could be leaking? Could I have inadvertantly loosened where one of the nozzle/valves is screwed into the rear or the pump body when working on lines at some point? Can remove that plate with everything else in place to temporarily get a better look at where leak is coming from?

Appreciate your advice...

have you checked if it is leaking out of the fuel cutoff solenoid? Took me a while to realise my leak was coming from there as it was dripping elsewhere...

thanks for your post - I didn't see it there but will look again with extra focus there...

if its the big bolt in the center of all the delivery valves there is an o-ring where that bolt is. need a special socket to take it off should be pretty easy.
