My Reading of this :- Everyone - any organised canalside gathering of more than 25 people, so all of the boat gatherings big (at more cost) or small, all of the societies gatherings, just about anyone they can get money from. Thinking locally - bumble hole, stourbridge, tipton, brownhills, titford, gatherings. Maybe even "organised cruises" such as BCNS Explorer or even the Challenge. Edited to add Cropredy, and that would definitely class as large scale and commercial ! springy

As Tony already said, they also look like 1/4" to me, but they look like Wade nuts, they are usually marked with the size on the machined ring of the nut, sods law says it will be underneath where its difficult to see. I would expect most chandlers would have them "on the shelf" rather than having to get one made. https://www.midlandchandlers.co.uk/products/ag-hose-fuel-1-4-od-x-18-long-ah-069 also available 36" and 24" springy

Browsing the RCHS images recently - I hadn't seen these before - 6 hand drawn sketches showing BCN Old main line water supplies and a couple of pages of information re pumps. https://www.rchsimagearchive.org.uk/index.php?album=Canals-Inland-Waterways/BCN/BCN-Old-Main-Line https://www.rchsimagearchive.org.uk/zp-core/full-image.php?a=Canals-Inland-Waterways/BCN/BCN-Old-Main-Line&i=045001E.jpg&q=75&wmk=RCHS transparent&dsp=protected&check=8ff3972802cbd31e8b31420dd4df5f9f42a9f4d3 springy

The S.U. electric fuel pump is a relatively simple device, as MtB said a solenoid, diaphragm, spring and NRVs. The (crude) pulse generator (contact points) also doubles as the pressure switch. Initially the spring holds the diaphragm in the "out" position, the solenoid operating rod is attached and passes through the core of the solenoid, the other end being attached to the contact breakers holding them closed. When power is applied the solenoid is energised and the rod drawn in against the spring, when it reaches the end of its stroke (Suction) the contacts open and the magnetic field collapses. Spring pressure now pushes the diaphragm out delivering the fuel, when the end of the stroke is reached the contacts close and the cycle is repeated. When the fuel lines (and carburettor) are full, back pressure holds the diaphragm against the spring - holding the contacts in the open position. As fuel is drawn from the pipes the pressure will fall allowing the contacts to close for another stroke. Note there is a clever double lever device in the contacts which means that they only open or close at the stroke limits. They were notoriously unreliable particularly when installed underneath the vehicle! Probably mostly down the damp air being drawn in around the contact points each time the pump cycled. Full instructions here:- https://www.mg-cars.org.uk/imgytr/sufuelpump.shtml I would be wary of trying to control the pulse width - it would make no difference until you got it under the "pull stroke duration" , at which point, yes you reduce the solenoid stroke and thus the fuel delivered, however the contacts would not open thus the full connect/disconnect load would be on your control circuit - its quite a chunky solenoid, I'd be curious to know what the current draw is when running continuously. Your "Drip Feeder" is clearly doing the regulation and the pump responding "on demand". springy

Hi YSA do you mean the buzzer is sounding and the warning lights if any come on but the engine does not turn over OR that the engine turns over but fails to start ? I don't know these engines but If it doesn't turn over then its not anything to do with trapped air, more likely to be a large multi-pin plug usually found somewhere on the engine, they are notorious for causing all sorts of electrical problems. Might just need cleaning sometimes just pushing the two halves back together or disconnecting and re-connecting may do the trick though it might be temporary. If it is turning over, it could still be the multi plug - if the engine stop is on the key rather than a separate "pull to stop" handle then there must be some sort of electrical stop control which could be affected by the multi pin plug. If it turns over does any smoke or obvious fumes come out of the exhaust ? springy

There's a couple of photos in the article I linked earlier (also same ones on twitter) - comparing those with google maps sat view I would guess somewhere near Richmond Road Bridge, (But that's only a guess) Possibly came in from the car park adjacent to the towpath next to the bridge, though it was obviously recovered from the non-towpath side. https://www.google.com/maps/@52.4409072,-1.8049236,81m/data=!3m1!1e3 springy

IIRC you can remove the diaphragm in situ without disturbing the gas side, drain the paloma and there are 4 screws holding the aluminium casting to the brass part, the two at the back can be a bit awkward to get a good line, try not to damage the screw heads. It is just possible that the diaphragm could only be weeping when the unit is in use as the diaphragm moves to allow the gas valve to operate, and seals itself when in the "static" position. springy

The obvious leak across the Brass housing is IIRC the vent from the back of the pressure diaphragm which operates the gas valve. It may be the rubber diaphragm has a slight weep. Though I would certainly check MTBs suggestion above. springy

Have you tried adjusting it - you can usually just hear the click as it opens and closes, then see what works or stops working. springy

Comparison with a horse is misleading, its 500w (or however much it can provide) is being put into the solid ground of the towpath and transferred through the towline, More realistic would be to compare an appropriate number of humans (500w worth) with oars attempting to row the boat, a couple of humans with long shafts punting would probably be more effective even in the soft bed of the canal. I remember some years ago being amazed at how quickly a horse drawn boat accelerates out of a lock compared with a motor boat. springy

I did some work assembling modules for the oil and gas industry (less than 5 years ago) and all the structural steelwork had metric dimensions and metric bolting, all of the pipework and stud bolts for joining it were specified in inches, however the stud bolt lengths were metric so I used hundreds of 5/8" UNC x 90mm long stud bolts for connecting 2" pipe flanges ! springy

Ensure you have a spanner which fits the bleed screws on the injector pump "Perfectly" (1/4" A/F if memory serves me correctly) - very easy to round the corners off with a spanner that's a bit sloppy, preferably a Hexagon ring as opposed to the more common Bi-Hex. springy

Might be worth having a good look around the ring on the nut which retains the copper pipe - if its "wade" brand they are often marked with the size of the compression fitting. springy

Where is the control valve - if it is also inside the reservoir then unfortunately then the PRV will most likely be inside as well, if the control valve is external then as BEngo said it could be part of the control valve but my guess would be on the pump itself so that when the PRV opens oil is just returned to the reservoir. If you remove the filler cap you might, with the aid of a torch (or even an endoscope), be able to see some movement in the oil when the engine is running (it might need some oil removing temporarily to make movement more obvious) which might give a clue. springy
