Does the fuel cell have a sump on the bottom to fit your fittings too? I'd just put the 044 straight onto that and get rid of the extra pump and surge tank as they are a pain in the ass. Or just put an internal pump in the fuel cell. The 044 can be used as an internal pump to.

304 requires 300 to 350 Kpa of fuel pressure to function correctly (3 to 3.5 bar), so a 5 bar pump will be more than ample, they can make a hell of a racket if it's a road car though.
If you use the Bosch as an in line pump under the bonnet that will deliver enough pressure and there will be no need for a surge tank.
You have overkill with the 044 and while I love overkill they are reportedly very loud. I would go for something with less pressure and flow (it will be physically smaller as well). I know the overkill temptation but it's not worth it for this job, imho just get one that has adequate specs.
If you can do a suitable gravity-fed setup (ie feed the pump from under the tank) then I agree with the above comment, just run your EFI pump inline without the other guff. You need that other stuff more when you are lifting fuel out of the tank.
My stock XJ-S (V12, definitely thirstier than a 304) had a gravity fed surge tank and the efi pump under that (the fuel tank sat quite high, under the parcel shelf).
In my experience as long as the main pressure pump is mounted lower than the bottom of the tank than no need for the pre pump and surge tank. The bosch 044 pump is way overkill. Could get away with a 070, which is a VL turbo pump.
Bosch pumps are very high quality, especially the motorsport pumps. If they die its generally from other issues.

We run 2 x 044 and a 15l swirl pot fed by a carter black on a Blown 383 , plenty of pressure and who cares about noise its a v8 fourby fuel pump noise is nothing .

If you check the fuel pressures for the EFI version of your car in the manual it may well be a suitable pump, then you just need to get one of those in your tank.
Alternatively just an EFI pump rated at 3.5 Bar and a suitable volume.

My ls1 commo intank pump is completely silent. They have a built in regulator aswell but that's only good for you if you need 60psi. Otherwise maybe try a vt 5L intank pump it'll be quiet and it may have a lower fuel pressure regulator which may be suitable? They are cheap as chips at the wreckers too and i haven't really heard of them failing.
