Run live wires off battery.

Run hose from tank out under car into drum.

Contact 12v + wire to prime pump - hold until tank drain's empty.

Wires from battery to boot.


Negative 'solid' on it's terminal, Positive not seen.


Line into tank

one spark and you could have been toast

lol, this'll sound bad, but i dont see whats wrong

[Nic_A31]

Sparks in fuel tank = not the brightest idea.

[lunjiaow]

lol. just connect the wires before you drop it into the fuel tank.

[Nic_A31]

^ No way. Not good for a fuel pump to try and suck up air, either kills them or makes them very very noisy.

[NA_Goodness]

Or connecting it solidly to to fuel pump and then touching the battery terminal with the wore so the sparks are up there! Lol.

Actually, sparks in a fuel tank aren't bad. The fuel pump does it all the time. It's when air is added to the mix you have a problem Like above...

[Nic_A31]

Yeahb ut the positive terminal on the pump has a rubber cover thing so sparks don't go flying off into the tank and they're never as big as the one in the video. There was a few bigger sparks last night when I was doing it too, could have gone hairy.

Wouldn't do it at the battery. Need to be at the tank when the pump primes up with exposed wires, so if it does catch on fire you know ASAP. Don't wanna have to walk 4.5 metres then realise "OH SHIT".

With all this said - I really should have just dropped the tank and drained it properly. But, I am still alive, so all good .

Tank all clean and good now? Hows it running?

[Nic_A31]

Yeah all clean now - gotta take it out and modify the bracket a bit for the pump but yeah running good.
Drove it for around and hour or two last night and only problem I had with car was fuse for pump blew, pulled over, a dude going for a run in Belmont stopped and helped me push my car off the main road and even ran back home and got me another fuse while I fixed up the terminal on the pump.

Alot of dirt in the tank and I think that "surge" area is a slow point. As you can see in the vid, the pump empties that area its inside of, in a matter of seconds, but takes considerably longer for fuel to refill that area via the plastic filter on the right side (in the pic) and vid. Would explain why the pump would run fine under no load but as soon as you give it stick it runs out of fuel. Under no load most fuel doesnt get burnt and gets returned into that area - under load it gets burnt up and the pump could quiet easily empty that area quicker than it fills up.

Lol, you´re a brave man. But good stuff dude.

What you think of "metro boy" people that exercise now?

[Nic_A31]

Eh? You referring to the dude that helped me ? he was too manly to be a metro boy.

And stfu - I got back into not being fat now. I ran a combined total of 20kms the other day. I'm fucking sore, but I did it, any everyone else was all like "zOMG that'd be tough man I couldn't do that".

That dude only went for a run cos he was being kept awake by some bunch of kids stuffing around at the park. Told em to fuck off, then they came back, so he told them again....stuck around to make sure he didn't get stabbed or anything.
