Just about to replace the female fuel hose on the boat with genuine Tohatsu part. This one connects to the engine. There's others on the boat as it has two 25 litre tanks on board that connect to a fuel filter.
At some point I must have ordered a Tohatsu part, but it was a pattern part, probably from Fleabay and has caused nothing but trouble, as the 'o' ring seal didn't seat properly and potentially caused fuel-related issues. It also didn't lock to the engine due to corrosion, and I know of one occasion when it detached. It's an innocuous little thing, but plays a big part in ensuring there's a proper fuel connection to the engine. I know genuine parts are expensive, but sometimes it's just not worth cutting corners.
