joakim, There's a few of ways to see if you are getting fuel to the engine. My preffered trick is to crank the engine for a minute or so and then crack loose the banjo bolt fitting on the end of the fuel rail and see if fuel sprays out. If your pumps are working it will, so no smoking. You'll need a 17 mm box end and a 19 mm open end wrench and as soon as it cracks loose the fuel will spray, then just tighten it back down (carefully, that is a hollow bolt). There are a pair of fancy little seals at those fittings but just cracking the fitting ussually doesn't damage them or cause them to leak. Losing fuel with a low tank and while going around left hand curves is the classic evidence of a bad pre-pump. Pre-pumps are cheap and main pumps aren't. If it was me, I'd guess I'd bench test them, but first keep in mind that the fuel pump electrical circuit is pretty elaborate and you should be sure that the problem isn't 'good pumps, no electricity'. You could always jump 12 volts straight to the pumps for that test. Always be careful with sparks and such when working around the gas tank or pumps dude. Cheers
