fuel slosh control

[knudsonm]

I think I might need to control the fuel in my carb a little better now that I started to get some OK 60' times(1.58). My final run last night really picked the front tires hard and I know I had my foot to the floor, but it sounded like I was in and out of the gas and the front end bounced much more than usual. I had plenty of fuel in the sumped fuel cell, so I don't think it was starving the carb.



I think I might need jet extensions and a vent tube baffle along with a improvised vent tube.



What have you guys done to help with fuel slosh?



I hope to have video soon...

The only problems I've had was slosh out the vents. Some years back, when I started launching in the 1.7 bracket, I was dumping out the primary vent on launch. A big puff of black smoke is a tip-off. A vent whistle fixed that. I also used to run a rubber sparkplug boot over the vent just in case.

............... Then for a while, I was doing burnouts beyond the box, then standing on the brakes before staging, and dumping out the secondary vent, flooding the engine. I just quit doing those burnouts. http://www.s10v8.com/images/smilies/icon_wink.gif

................. I've got secondary jet extensions, Can't say that I've ever needed them. http://www.s10v8.com/images/smilies/icon_razz.gif

K- are you sure your float level is set correctly

You MAY need to raise it on the secondary side. I'm sure Grim , Ray , Zoomora might have something to say. Send me that pic from the rear showing your 28x10.5's on 10" wheel.

Later! James-

This pass is from much earlier in the day and it didn't have the problem. No video on the pass with the issue yet.

what kinda fuel pump?? jet extensions and something on the vents is something you need to do.

[knudsonm]

My fuel system consists of a Summit sumped fuel cell, -10 line to a large BG filter, Holley Blue pump, more -10 to a Summit(Aeromotive) regulator, -8 to each bowl. It built the system a little big for future growth.

All I have is jet extensions. I don't have any trouble (yet) with the vents though.
