Splitting fuel line for twin engines

Just fitting twin engines. I need to get a Twin lift fuel bowl. Where the fuel tank goes in one side then two hoses come out the other side. Any ideas where I get one from?

Why not use separate fuel tanks and two bowls?

Alternatively,you can get another take-off barb for a standard Quicksilver bowl if it'll flow enough fuel. They have the threads in them and a blanking plug yoiu just unscrew,

carefull if you run two engines of one fuel bowl, (it could make the engines run to lean)and cause damage, it would be better with two separate fuel systems as Nos4r2 suggests

Standard Racor bracket has provisions for dual inlets and outlets. I'd go with a separate filter for each engine (at the least. I would have to think about going to separate tanks; I seem to have enough trouble remembering to monitor level in one.)

I was thinking of taking the fuel hose to the transom form the tank then splitting it with a T connector with each one going into a separate water separator then into the engine. The engines have come with their own water separators. Will that work or do I need something else. Is a bowl a water separator ?

Do as you suggest above. Run a line to the transom and split to the two filters/water separators. Ensure the line is big enough diameter to supply enough fuel to both engines at WOT. Consider putting shut off valves in case you need to isolate an engine for any reason.

The order of parts should run - Tank - filter/separator - primer bulb - engine. Think about how you connect to the filter and engine etc in case you want to run either engine on an auxiliary tank for any reason. This can be done in many different ways to either connect straight to the engine or through the individual filters by using standard fuel line connectors in the desired places rather than hard connecting everything.

Mine has 2 lines coming from the sender unit in the console to 2 Racor filters that has 2 inlets so I am having 1 permanent main feed and then 2 quick connectors for auxiliary tanks.

Unless they're self sealing when unattached your gonna need several fuel taps!
