Thankyou for turning up for class lol, Drewdog, Deano and Mark .
Mark, your buying a Link ecu or have done so, glad you've made your choice. I don't know much about standalone ecu units except a lot are easy overpriced for what they are and do. Keeping the tech backup in Aust is prolly a good plan for future.
I'm still going with speeduino as I'm not after anything fancy or pub ammo , having a ecu for $300-500 rather than $2000+ allows the saved money's to be spent on other needed stuff, firmware might be from UK? But they are very knowledged and helpful. I was going to use AEM from USA which actually is designed for a motorbike ! Anyways I'm still a long way from doing the ecu in my project .
Here is the tank inlet position after some head scratching I used a piece of scrap sheet metal and punched a hole in it so the elbow tube and making a strip with a fold to get the correct angle the inlet needs to be at, once worked out I transferred the template to the tank and proceed to holesaw the tank. I only had a 45mm so I bent up the hole edge to make the hole bigger and have something to weld to

Here is a test rig using a length of plumbing pipe to get the angle and length right

This is the rubber fuel safe pipe I'll be using, it has a 50mm I'd to match the elbow pipes

There was some slight snip action to allow the tank be placed in it's position on the boot hinge support panel, nothing that'll compromise it's strength

The original inlet pipe on the tank was plugged up using braze wire

I also Tig brazed the the elbow in place as the elbow is stainless steel and the tank is mild steel, braze is the only way to join them together
