Most likely the booster pump was added due to the main injector pump being
shot. Common leak point is the pump haft seal-bushing. This leak point also
causes the pump to loose prime often making starting difficult. The pump
probably needs a rebuild. The windshield washer pump may not be compatible
with diesel fuel so that may also become a leakage-fire source.

Subject: 82' Diesel 1.6 NA Injector leakage

Learning about Fuel Lines, Fires and Halon is Terrific.  THANKS for minding
the Newbies.
This is still my first year with my 82.

We were  ready to leave and go camp up at a beach front site  at Assateague
Island National Seashore, Maryland --- AND THEN

I see diesel fuel leakage at the base of the Injector.

The PO had installed fuel booster pump in the fuel line ahead of the
injector pump,  mounted on the rear engine well wall behind near the license
tag.  (Its actually a windshield fluid pump)
He said it was to improve cold winter starts.   It works.  The diesel
always starts easily anytime winter or summer.  Runs well.

But diesel fuel seeps onto the bracket below  the injector pump body.  None
of the fuel hoses or pressure tube connections is damp.

*1) Could seeping be from pushing fuel supply into the injector pump? *

Test one
If I  disconnect power to the booster pump, the engine starts, sputters and
cannot run. So the booster must impede fuel flow.

Test two
I disconnect the booster - reconnecting fuel supply line from the filter
cannister to the injector pump.
Seeping seems to have stopped.

2) *What do you all think of the booster pump? Just reconnect  in winter if
needed?*

*3)  Is there any concern need with the injector pump?  Did the booster pump
harm it?*
