Wow, what a pain that rear filter is! Long story short, I went with a NAPA 3299 which is 1/2" but the hard line to the fuel pump is much smaller, probably 3/8 so I basically just cranked the hose clamp until it sealed but I don't have confidence that it will last. I'm going to try and find a 1/2 to 3/8 reducer and then use the proper lines to make the step down. It's really amazing how difficult it is to find a simple reducer to use here; no one local has it and when looking online you have to deal with the NPT vs actual size issues and then who knows what you're going to get. Friggin' plumbers!
Then I replaced the front filter too. That thing really lets loose a whole lot of fuel and then the plastic fispa filter container is sketchy at best! Not sure what the alfa folks were thinking when they designed the fuel supply....
Anyway, it's running great, it actually seems to have more power or at least be a bit more peppy. And no fuel pressure light but I have to say that I think it may have been the combination of the rear filter with a bad fuse connection as the fuel pressure light stopped flashing after I messed around with the fuse a bit more. Also, the pump was making strange noises but now it seems better. I may have a fuel pump replacement in my future....And it has the 3 outlet pump so that should be fun.
Thanks for the help. What's the secret to maintaining a working fusebox? My headlights also come and go and the connections are clean, all the fuses are new or in good shape. They just don't maintain a connection. I've squeezed the fuse connectors tighter, I've roughened the fuses and connectors, I've cleaned everything, and still it just won't keep continuity.
