JR Posted August 23, 2015 Author Share Posted August 23, 2015 Cheers Yeah it came with the whole loom wich is kind of half the problem, lots and lots of wires that arnt required. I'm almost there, there are a shit load of sensors and wires that are required for such a wee engine. I just need to tidy it up now really. I had another play around with the pump and it seems it's not self priming without the initial gravity feed... I'll have a think about it.

Truenotch Posted August 24, 2015 Share Posted August 24, 2015 You could add a relay that will prime the pump when you flick the ignition on? 1 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 24, 2015 Share Posted August 24, 2015 sounds like the best option. but do they shut the pumps of at all during engine running? the power supplied by the relay could stop this happening if so.  my suggestion would be to add the relay, but have it switched on by a momentary switch/button. so you can press it for a couple seconds before hitting the ignition and have the ECU take over fuel pump control again. Quote Link to comment Share on other sites More sharing options...
Rookie Posted August 24, 2015 Share Posted August 24, 2015 If the pump inlet is below the fuel level then there will be sufficient head to allow it to prime, I would suggest that your issue is somewhere else. Is it negative switched from the ECU and you have the relay wired up all wrong? Also the fuel pump will run while the engine is, but will stop if it does.

Rookie Posted August 24, 2015 Share Posted August 24, 2015 Just to clear things up, can you describe/ take photos of the setup? Also can you make it run at all? Quote Link to comment Share on other sites More sharing options...

I was trying it with a temporary set up regarding the fuel. And by temporary I mean really shit. I just had the fuel pump trying to suck fuel out of a bottle. The bottle was below the pump and it wouldn't suck the fuel through, the pump runs fine but I think it needs that gravity feed to get going. I haven't sorced a fuel tank yet so I don't know how low it will sit in the tail, but I suspect the lowest point of the tank will be lower than the pump... I'll add a picture in a couple of days, I'm away from home at the moment. Skinner, now everyone knows even my baby can grow more facial hair than me. 1 Quote Link to comment Share on other sites More sharing options...
downtrail Posted August 25, 2015 Share Posted August 25, 2015 Pump should have a check valve in it if not put one after it once its primed it should keep primed. 2 Quote Link to comment Share on other sites More sharing options...

JR Posted October 20, 2015 Author Share Posted October 20, 2015 For the last while I have been trying to sort out the clutch and throttle. I want it to be really simple for the wee fella to drive while he is little, just a go pedal and a stop pedal in one gear only. Then when he is older he can have all five gears and a clutch to play with.... In hind sight I should have gone with a smaller simpler engine.  So I have been playing around making a throttle pedal that controls the clutch and the throttle.. I am up to the 4th version, the first three used springs and levers but I just couldnt get it to work with out my son needing Arnold Schwarzeneggers legs.  Here it is, I bought a chinese hydraulic clutch set up and made this abomination.   I need to tidy it up and strengthen it. It probably belongs in the design disasters and fabrication foibles thread, but eh, it seems to work. 9 Quote Link to comment Share on other sites More sharing options...

NickJ Posted October 25, 2015 Share Posted October 25, 2015 Awesome! is it possible to put the spring onto the clutch lever directly as a fail safe? if it all goes west the clutch is depressed and the car stops rather than drives on 2 Quote Link to comment Share on other sites More sharing options...
