after getting my injection a bit more sorted i now have a problem that when i turn right at some speed i get fuel surge,the tank (ally) has a baffle in it but seems to be more holes than plate also when draining the tank i noted fuel stopped running while there was still 1" of fuel in the tank,pick up is right on the bottom.
i thought about putting a banjo fitting in the middle of said tank,obviously its difficult to get a nut on banjo bolt so i found this. https://secure1.actinicexpress.co.uk/shops/partsforaircraft/index.php?section=64
one from the bottom,a push in 90 deg outlet,its sposed to be for aircraft use,any thoughts?

Ideal for adding to the top of a tank as a return.

There will still be an amount of fuel That you can not pick up, its only 6mm and is the tank thick enough to hold it?

I had the same problem with the stock tank (MG Midget) and just made my own in Ali, I put 2 baffle plates with no holes in either side of the intank pump. They go almost to the top and have a very small gap at the bottom, It seems to work fine.

Have you thought about adding foam to the tank?

there is no access to the insides other than the filler neck,i dont have acces to tig,foam is a maybe,ill give the aircraft mob a bell and see it they do one in 8mm.cheers peeps
