I'm a bit late to this discussion but it is of interest to me. My small low wing two-seater (Gazail 2) has wing tanks forward of the spar and the original builder (I bought it as an unfinished project) was intending to run fuel lines straight from the tanks to the distributor pump (diesel engine). I see this as a recipe for disaster so I've installed a separate central 5 litre sump at the lowest point which the two tanks will gravity feed into. This sump has its own little sump protruding below the floor which will provide a scavenge point and test/drain valve. I'm thinking I will need to vent this tank so it doesn't trap air when first filled. I'm told the distributor pump, once primed, will have enough lift so I won't need an electric pump.
Can anyone see any problem with this system?
