Can you clarify the problem a little more?

There are rubber/neoprene/flexible/black hoses that connect the tank-filter-Spicapump, yet you mention that they are "corroded", which sounds more like metal. Which is it that you feel is bad - the metal coupling or the rubber hose (or the hose clamp)?

If it's the hose, then Alfa generally use 8mm which is very close to 5/16" (a Spica expert should verify this). You should use hose designed for fuel injection pressure. Your local NAPA auto parts store will carry this stuff - bring in a sample of the old hose, or better yet, the fitting it needs to go onto.

If it's the banjo coupling, then the issue is likely to be the two brass washers that go on either side of the steel fitting. These become work hardened over time, or scratched, or just don't get seated properly upon re-installation. Again, a NAPA store will have an assortment of these brass washers - just bring in your old parts.

With all fuel leaks, finding the source of the leak is usually 90% of solving the problem. You might dry everything off, and then have a friend turn on the fuel pump while you watch the area of the leak for the first sign of gas to find the exact source of the problem.
