Hi all,
I have a petrol engine in my recently bought boat and have noticed it doesn't have a water seperater on the fuel line. It has the fuel filter of course but no bowl to see or drain off any water.
Should I fit one? Where can I get one?
Many thanks in advance.
Syd

Yes without doubt fit one. Biggest cause of trouble is mucky fuel or water in fuel.
Suppose you get them from the chandlers like everything else boaty. Might try a good truck parts shop though and save £££££££

I fitted one to my petrol engined boat, it had a glass bowl which meant I could see any water.
The surveyor recommended that it should be changed for one with a metal bowl.
The insurance company latched onto this and insisted.
I couldn't find one with a metal bowl, so my choice was to remove it or have one made. A friend turned up an aluminium bowl and I tapped a thread into the bottom and fitted a drain screw, to check for water.
I still think the glass bowl was safer as I now have to open the drain and to see if I get water or petrol out. Which means I have to drain into a container with the risk of a spillage.

I was about to fit one to my petrol engine before it went pop so fitted it to my new diesel engine - made by Lucus it comes in three parts, top with 4 ports two entry two exit for flexability, middle section is the filter which is replaceable and the bottom is an ali bowl with drain off - really solid good piece of kit for about 35 quid.

regards

Re: Fuel/Water Seperater-cheapest

Go to a scrap yard for commercial vehicles buy one secondhand any cav or AC will do. Ex diesel ones sometimes have three connections extra one may be return flow from Diesel injectors. When connecting you usually have a choice of flow direction usually there are arrows on the top of the casting. Make sure you connect to flow so that incoming flow connects to centre of the filter that waycollected water will drop into the bowl. Fit a new element and make sure all the seals are fitted correctly and snug in their grooves.
If you fit the filter on the suction side of your pump expect to change it at least every 12 months as slight clogging of the filter will slow fuel flow.
