This is a shout out to all of you Spica Guru's. I have a good running Spica system that will rev up fine but the fuel pressure light is flickering.

1. Re built Spica
2. New TFA
3. All spica settings good.
4. New fuel filters
5. Revs fine but sputters under acceleration.

I am thinking poor connections to the fuel pump or possibly a weak or failing pump. The car is a 1979 and it is the original pump.

Any thoughts would be appreciated.

Flickering light

Have you replaced the Alternator with a higher Amp one from a late Spider/Milano/GTV6?? Makes a difference with the fuel pump, to have volts.

I'll second the fuel pump but check this first: pinch off the flex fuel lines on both sides of the rear filter, disconnect and remove the rear filter without inverting it (keep it level), invert the filter over a catch bowl (intake side down) tap firmly with a rubber mallet on the exit side of the filter (which should be pointing up) see what ends up in the catch bowl, if you find crap, you'll need to have the fuel tank serviced and replace the rear filter. Danger!since your working around gasoline, practice all safety precautions!

fuel tank ok

I pulled the tank, drained it and replaced all of the fuel lines and filters. I think it is the fuel pump.

go to www.wesingram.com/hp.htm and download the Fuel System Diagnostics Guide.

Sounds like a failing fuel pump, especially since it's still original. Check the in-tank pump as well since the internal hose connector could be failing. It's all in the Diagnostics Guide.

Pump or filter. When my light flickered, it was always the rear filter, due to rusty tank. The problem went away after the tank was refurbished.
