Gravity feeding diesels

[premmington]

Gravity feeding any diesel pump. To prove delivery of fuel to any diesel pump. By excluding, the vehicle tank & pipe work, filter, filter housing & non-return valves fitted to some systems. Over the years I've used anything from a funnel, to several specialised expensive service tools. But this is my current tool of choice, which I fabricated myself. It consists of: one litre camping water bottle with 20mm hole bored thru lid, 20mm electrical grommet to hold pipe in bottle, 1200mm of translucent pipe, one diesel prime-ing bulb with an internal one-way valve (sourced from a Citroen). One banjo fitting bent at 90 degrees (sourced from dead pump). One 20micron inline air filter (all thou a Merc inline fuel filter would do, they only cost £1.92). A few hose clips. The fittings on the banjo are only there, to plug it after use to save spillages, ingress of dirt. In use, you would use the fittings & copper washers from the pump being tested.
In use, it will make a good connection for a test drive. If you also plug the pump leak-off venturi/port, you can get a longish test drive from 1000ml of derv (round the block). The clear pipe & bulb allow you to bleed pump up, without having to invert the bottle, the filter & banjo plugs will stop contaminants reaching the pump. Angled banjo fitting allows connection to top entry and side entry pumps. The translucent bottle is soft in construction, so collapses under vacuum, no need for breather hole & thus associated spillages. Only use translucent PVC pipe so you can see where the air is.
