dan1120 0 Posted April 15, 2008 Got r1 carbs on my car took it to the rolling road today,and at the top end was running out of fuel,ive got my facet fuel pump bolted to the inner wing,but the bloke said i should put it in the back near the fuel tank as the facet pushes fuel better than drawing it??is this right if so can i use the ign fed live from the excisting fuel pump??and do i have to run a new fuel pipe in from pump to my filter king or can i use the old fuel pipe some how??

It shouldn't be running out of fuel ! My 16v is running over 200bhp and using a facet red top with no issues of running out of fuel. And thats mounted on the inner wing. Maybe you have a restriction somewhere ? Did you know the Facet Red top has a fuel filter built into the end so you don't necessarily need a filter king imo. Check the pump is getting the right voltage (s*itty connectors etc) as they are very sensitive to a voltage drop I have found. Share this post Link to post Share on other sites
swordfish210 20 Posted April 16, 2008 Hi, funnly enough i had my bike carb'd XT on the rollers the other day and it was running out of fuel at high rpm. The problem was that i didnt have the carbs angled down enough and it was draining the fuel out of the floats just enough for the main jet to stop picking up the fuel. How much mave you got your carbs angled at? Share this post Link to post Share on other sites

This is only my experience on the Webber carbs I've had running my 8v and 16v for near on 7 years with no issues in that area. Share this post Link to post Share on other sites

bensonmi 4 2 Cars Posted November 25, 2008 had that problem before on an old xr3i (shame) on twin 40's when the facet was up front, so moved it back closer to tank in the original position and it worked a treat. also never used a regulator with them.
