Thanks Craig, your advice seems to match similar that I have heard but which is probably not confirmed to this point.

I need to get a stock pump with its own surge tank as my fuel tank is unbaffled yet I have seen a number of commodore pumps on ebay that have no surge tank around the pump at the end of the pick-up.

I can only presume that these car's tanks had inbuild surge protection of some kind.

Looked at the XD pump tonight and it is actually more like 220mm tall and the sealing lid is 130mm in diameter. So the pump's 20 mm taller than the tank and as my tank is ribbed for strength and only offers a 110mm wide flat entry width on top, the pump is also 20mm too large in diameter.

I have toyed with the idea of a side mount pump, as a lot of the holden pumps were designed to be fitted, but have yet to see a pump in its own surge tank. Side mounting may offer me greater flexibility in getting a pump to fit and be capable of scavenging of the bottom of the tank.

Can anybody suggest any other pump option?
