Installing Fuel Tank - must dos

Hello,

I'm planning on ripping out my old (broken) fuel tank in the bow, and replacing it with a shiny new one.

There is no plumbing whatsoever from old fuel tank to outboard -- current outboard runs to tote tanks at the back.

I've got a semi good idea what plumbing I need to do, but wanted to double check... is it as simple as:

new fuel tank --> pipe --> fuel filter --> pipe --> outboard

I'm hoping to be able to have the tote tanks as optional, so might do this:

new fuel tank --> pipe --> two way switch --> fuel filter --> pipe --> outboard
tote tanks --> pipe --> two way switch....

nothings missing from that idea is it?!

Oh, and fuel filters:
http://www.smartmarine.co.nz/can-typ...ry-p-8283.html -- $80
http://www.smartmarine.co.nz/marine-...el-p-8286.html -- $180
http://www.smartmarine.co.nz/disposa...m-p-10579.html -- $10

Why the huge price difference, and what one?!

At present, I only have whatever inline filter is in the actual outboard....

The cheap plastic one woesn't separate water, the next one has an alloy head and disposable filters, the last and most expensive has a stainless head and clear bowel at the bottom so you can see any water/debris that have been caught.
I've buy the last one if it was me, saying that I have no filter fitted apart from whats on the engine and never had any problems.

If it's a metal tank, it should be grounded and anoded (I think.)


Go with the Racor filters (or the European equivalent, I suppose.) Easy to find and well proven track record. The plastic bowl, while it seems gimmicky, makes it pretty easy to see if there's a contamination problem should the need arise.

Yup, has a filler with built in vent already from the existing (broken) tank.

Anonded, very good point. Silly question, but grounding it - it's a fibreglass hull and deck... how does one ground to that?

If it's glass, I don't think you need to do anything. The grounding is more to prevent galvanic corrosion than to avoid static electricity.
