The Alfa Romeo GTV6 fuel pump is fed with gasoline that passes through a fuel strainer at the bottom of the fuel tank. It can be unscrewed from the tank with a large 32mm socket after you remove the banjo fitting for the hose on the bottom. The banjo fitting bolt is 13mm. When you remove the banjo bolt, you should hold the base of the filter with a 32mm open wrench.
The base of the filter is a soft metal and has likely been screwed into the tank for decades. Make sure you clean and around the threads and use a good penetrating fluid to give yourself every chance of getting this filter to unscrew. Hopefully, yours will come free.
Before you do all this, you must figure out how to drain the fuel from the tank. Don't cut the feed hose unless you have a replacement, as it is not the easiest to find. The size of this hose was originally 12 mm and could have been replaced with the easier-to-find 1/2 inch size. Ensure you get a fuel hose and not the more common heater hose. The hose should also be ethanol-compatible if that's what is used in our area.

Alfa Romeo GTV6 Fuel Tank Strainer and sealing washer and Oring. The GTV6 fuel tank strainer has long been discontinued. The Alfa Romeo part number for this was 0060523420. The filter was made by FISPA*, and the part number is 3160.02.
Hopefully, yours is still serviceable, but if not, the only way I have seen to get one is to scour eBay or other "for sale" sites.
Alfa Romeo GTV6 Fuel Strainer Specs
The outside thread size of the Alfa GTV6 Fuel Tank Strainer is 40x1.5mm. The inner thread where the banjo bolt is screwed into is 22mm.
Other car companies like Porsche and Mercedes-Benz use similar in-tank fuel strainers. However, I have not found a substitute filter with the same thread size.
Alfa 6 Fuel Tank Strainer
The Alfa Romeo Alfa6 sedan uses a similar 40mm outside thread filter. However, the inner thread size is only 18mm, not the larger 22mm used on the GTV6. Using that filter will limit fuel flow going to your fuel pump.
The Alfa Romeo Alfa 6 Fuel Filter part number that is not recommended is FISPA 316003 or Alfa Romeo part number 119203202600. This old part number was superseded by the new Alfa Romeo part number 60737161.
Alfa Romeo GTV6 Fuel Tank Strainer Sealing Washer
The Alfa Romeo GTV6 Fuel Strainer sealing washer is a copper washer with an inner diameter of 41.95mm. The outer diameter measures 48.77mm. The thickness of the used washer was 1.51mm. Unsurprising, this M42 washer is not the easiest thing to find.
After much searching, The closest I found was this 42mm inner and 49mm outer, 2mm thick, DIN 7603 Copper Sealing Washer at the Misumi USA. Misumi is the world's largest supplier of fixed and configurable components for the manufacturing industry.
Alfa GTV6 Fuel Strainer Washer Outside Diameter is 48.77mm
The Alfa GTV6 fuel strainer washer thickness measured 1.51mm.
Alfa Romeo GTV6 Fuel Tanks Strainer Oring
A replacement for the Alfa Romeo GTV6 fuel tank strainer Oring is no longer available. And even if you did find one, it may not be ethanol-fuel compatible. One of the more significant hurdles is finding one that is compatible, and measuring a used shriveled-up Oring is difficult. After much research, I decided on Buna-N 70 Duro Orings, which are ethanol-fuel-rated.
I'll confess that I ordered dozens of Orings trying to find a size that would fit like the original. These Orings were often only available in bulk, and I spent over $100 never to come up with a definitive size.
I settled for a 34 x2.5 mm Oring that seems to fit well. This is a decision you'll have to make for yourself. To ensure no leaks, I used an ethanol-fuel-safe thread sealant. This would normally not be necessary if all these parts were available from Alfa. Again, it is up to you.
Fuel Thread Sealant For Ethanol Applications
Because I had a hard time finding the exact size of the ring for the fuel strainer and to make sure I didn't have an issue, I used this thread sealant made specifically for sealing gas fittings for ethanol applications. This sealant is also compatible with Buna-N Nitrile O-Rings (NBR) . I would not use this on the banjo fittings. The copper washers will be fine.
Alfa Romeo GTV6 Fuel Tanks Banjo Fittings
The Alfa GTV6 uses banjo fittings to connect the fuel hoses to the fuel tank. The larger banjo fitting is the fuel feed from the fuel strainer. The smaller fitting is for the fuel return hose coming from the fuel pressure regulator on the engine. You need to change the sealing washers whenever you remove these fittings. Here are the sizes for your convenience.
