[Vwdiesel] diesel / veg strange problem

[Evans Antoniou]

hello all,

i live in montreal canada and drive a 96 jetta with
the AAZ engine that runs on veggie.

i have my veg tank in the engine bay where the battery
used to be.

i have an aux fuel pump that runs both on veg as well
as on diesel. when i first installed the pump i would
purge in 90 seconds but lately it has been taking
quite a bit longer. air has also been filling up in
the IP taking upto 10 minutes to purge.

i tried running w/o the pump, removed filters, added
transparent fuel lines, replaced overflow fuel lines
from injector to injector and nothing.

today i decided to remove each overflow end to see if
there would and should be a mess to my understanding
and this is what happened.

injector #1 and #3 return very little fuel or flow and
the other two function properly. does this mean they
need and cleaning and can using a bottle or two of
diese purge fix the problem?

this is the flow my veg to the IP. tank, filter, fphe,
vegtherm, injection line heaters; can switch from a
closed loop or return to tank. 

it takes the same amount of time to see diesel return
while on veg and vise versa.

the conversion has been working pretty good for the
past year or so.

thanks for reading.
