Have wondered about that think I will get two taps to be sure I haven't done it yet but could put a tap on and a quick connector on the tap.

you'll also need a tap on the line from the tank

I would be worried about a single fuel line being able to feed these babies at WOT - should be a great rig BTW

Mick - this is what you need - 2 x supply lines, 2 x filters, 2 x taps. Oddly, the bulbs were in different locations on either side, but it didn't seem to make any difference...

Would have to agree with the above. I would not under any circumstances run two engines from a single supply. Must be separate supplies to feed each engine. It is also much safer in the respect that if you get any contamination in a tank then you always have a backup. As uncle al mentioned it could cause fuel starvation problems in the engines and should the engines run lean then you will have no comeback with warranty on any engine. Also remember to pipe the engines correctly I.e. no fuel primer bulbs and use 10mm Id fuel hose all the way. Will be a machine when it's ready though those engines are absolutely incredible. Good luck. Peter

Use these if you want to be able to quickly disconnect the main fuel line and connect an auxiliary tank in place.

MERCURY FUEL LINE TANK END CONNECTOR QUICK RELEASE KIT BOAT OUTBOARD | eBay

I've seen a twin engine/twin tank set up use these to enable both engines to run off either tank by having a split pip with two connectors from each tank. Each filter had a brass connector for connecting which ever fuel line you like. Both engines could be connected to the same tank or run off their seperate tanks. Guess you could set up a similar system with various pipes and taps.

Can't you just have the primer bulb next to the engine

If you trace them out, you can see they were both ways! I guess with wee 90s on those big hoses, it didn't matter a whole lot?

Did you run your engines on 25 litre tanks then, no fitted tank?
