[alfa] RE: SPICA Fuel Pressure Problem

["Jack Smith" <roadtrip999@xxxxxxxxxxx>]

What kind of replacement pump did you install? If it was a Bosch supply pump 
from a L-Jetronic Alfa (inlet and outlets in-line on the ends of the pump 
body), you need to solder up the outlet fitting on the injection pump and 
redrill it with a 1/16" drill. That should give you a good 15-18 psi at the 
injection pump itself.

It's possible that it could be a heat related problem. 69's did not have the 
boost pump in the tank to ensure positive feed to the supply pump. If the 
fuel level was very low, the temp and pavement VERY hot it's possible that 
the fuel overheated and caused the pump to cavitate but I doubt it this time 
of year, and certainly not in Denver.

Do check the fuel vent system to be sure it's breathing.
