Is the fuel tank pickup screen accessed from beneath the car or is it
on top of the tank? My 300D is sucking air into the fuel line from a
pinhole, and it seems like there is an awful lot of vacuum on that
line - what is normal vacuum for feed line?
'82 300D Turbo 196K
The filters are new and the connections are tight, and I know that
there is a hole in the supply line since there is a little pool of
diesel under the car when I let it sit from where it leaks down. I
can see bubbles in the fuel if I open the throttle at all...
In my Haynes manual it shows the pick-up screen as coming in from the
bottom; this is OK though since I have to empty the tank in order to
repair the fuel line anyway.
Has anyone measured vacuum at a tee before the lift pump for an
un-restricted fuel system? I am at 5~10 in. Hg at highway speeds,
which seems like an awful lot for a 6mm supply line.
