[alfa] Spica Fuel Pump alternatives?

["John S." <roadtrip999@xxxxxxxxxxx>]

Kevin - If I had to guess, I would say that your supply pump is slowly going 
bad since you ran it without the rear filter and still got an occassional 
light.

That said, I would:

1. Don't run the car routinely with an intermittent fuel low pressure light 
and don't run it at all with a constant one. FI pump damage can result.
2. Replace your rear filter and the rubber fuel line from the tank to the 
filter to the pump. Use 1/2" line, not a narrower line.
3. Replace your front fuel filter if it hasn't been changed recently.
4. Check the inside of your fuel tank for setiment and rust. A dirty tank 
will clog filter very quickly with the kind of recirculating fuel flow that 
the SPICA system relys on.
5. Check the electrical connections to the pump clean and tight. Check for 
full voltage at the pump terminals.
6. If after you've done those things, if you're still getting a low pressure 
light, even occassionally, replace the pump. I recommend the supply pump 
from the L-Jet Alfas. The only mods you'll have to make are: a. Use a little 
rubber spacer material for the present bracket to grip the slightly skinner 
L-Jet pump.  b. Change the elec terminals to ring-type.  c: Solder up the 
3/32" restrictor in the SPICA pump outlet fitting and redrill with a 1/16" 
drill. That setup should last the rest of the car's life. It will also give 
you a good solid 10 psi feed on battery only and 15 psi with the alternator 
running.
