Neil Clark Posted March 19, 2020 Report Share Posted March 19, 2020 I'm re-assembling the car and between the copper fuel pipe to the carb and the rubber pipe is a curious black connector. It screws onto the base part. I don't see what the function is unless it is a filter of some sort? Does anyone recognise it? Link to comment Share on other sites More sharing options...
68vitesse Posted March 19, 2020 Report Share Posted March 19, 2020 Is it a one way valve, usually has an arrow on it to show direction of flow. Regards Paul Link to comment Share on other sites More sharing options...

NonMember Posted March 19, 2020 Report Share Posted March 19, 2020 A one way valve there shouldn't be needed (and was never a factory fit) because the fuel pump has one-way valves internally - that's how it works. It may have been fitted to mask a problem with the pump, or it may just be one of those unnecessary "must haves" that Pete started a thread about.

Peter Truman Posted March 19, 2020 Report Share Posted March 19, 2020 next t the relay on the chassis is another item in the fuel line indicated by the 2 sets of pipe clips, "What is This" Not an electric pump as there's a mech in place.

Neil Clark Posted March 19, 2020 Author Report Share Posted March 19, 2020 So I can replace it with a simple filter? Link to comment Share on other sites More sharing options...
DanMi Posted March 19, 2020 Report Share Posted March 19, 2020 what is the 3 way joint in the brake pipe on the bulkhead for that is not standard Link to comment Share on other sites More sharing options...

This being a very early car, the hydraulic switch is probably correct, although I suspect that specific fitting isn't. Link to comment Share on other sites More sharing options...

That appears to be it, Rob, and you're correct about the location - it should sit on the main chassis rail just in front of the bulkhead, not on top of it. As long as it works, that's the important thing. Link to comment Share on other sites More sharing options...
dougbgt6 Posted March 20, 2020 Report Share Posted March 20, 2020 Ah! Confused me for a moment as a 3 way coupler is correct for a late GT6, which this isn't of course. I've had a couple of mechanical fuel pumps and repair kits, but I still get drain back. OK for a couple of days but, noticeable after a week and after winter lay off hand primer pumping required. I've often thought a one way valve would be good. Doug Link to comment Share on other sites More sharing options...
Neil Clark Posted March 20, 2020 Author Report Share Posted March 20, 2020 Working in very slow brain mode, thinking about it on the MG side, those with Weber's (mines got SU's) often complain about finding them often slow to get going, needing priming. Could it be that this is the non-return valve mentioned above, to keep more of a head of fuel for the Weber? Link to comment Share on other sites More sharing options...
Neil Clark Posted March 20, 2020 Author Report Share Posted March 20, 2020 I dare not fire it up yet so may have to wait a while to dig further. Meantime I'll fit a filter just before this mystery object since I suspect that post the accident, insurance storage, dusty warehouses, dismantling etc who knows what has got where.

Pete Lewis Posted March 20, 2020 Report Share Posted March 20, 2020 thats why the pump has a NR valve inside ,how many do you really want Pete Link to comment Share on other sites More sharing options...
DanMi Posted March 20, 2020 Report Share Posted March 20, 2020 there is no mention of a hydraulic brake light switch in the mk1 spit parts manual, though I agree that's what it looks like and where that brake connector is located is where the starter solenoid would normally be. So long as it works Link to comment Share on other sites More sharing options...

So long as it works Early Heralds, to about 1962, had them; there's no bracket at the pedal for a stop light switch so have a look at your brake pedal; if there's a bracket you have the option of either switch but if not, you'll have to stick with the hydraulic switch or fit a later pedal. There should be a connector on the chassis, just to the left of where I can see your yellow stand, and that's the mounting point on the Herald.
