RGTorque Posted June 8, 2009 Share Posted June 8, 2009 Im having a lot of slosh in my 12+ gallon tank and im looking to fuel foam for the solution. Any recommendations or brand preferences? Link to comment Share on other sites More sharing options...
powderbrake Posted June 8, 2009 Share Posted June 8, 2009 (edited) One source is http://www.Speedwaymotors.com item # 6007050A My set-up is older, before Brian started using in-the-tank pumps. I have my fuel pump mounted externally, at the bottom rear of the drivers seat, with a large fuel filter in the pump pressure outlet line. I have a small transparent filter in the suction line after it exits the top of the tank. I occasionally find small pieces of the plastic foam and junk in that pre filter, which I have changed once in 4 years. From this experience, I would suggest a sock filter on the pump inlet if you are using an in-the-tank pump.

RGTorque Posted June 8, 2009 Author Share Posted June 8, 2009 hello, i have the same tank pump setup as you. i am thinking about using fuel foam on the sides of my tank and weld in some baffles closer to center for a quicker pickup in the center. im trying to avoid buying a second tank and pump. id love to see what others have dont to resolve this issue.

powderbrake Posted June 8, 2009 Share Posted June 8, 2009 I suppose you have the original 13-14 gallon tank, sort of a triangle shape. That is what I have. I thought that my tank has a box around the fuel pickup point in the center-front of the tank, but I forgot what it looked like in there when I installed the foam through the gas cap opening. If you are going to weld in a baffle, then you will have to open up the tank. If you do that, you could construct an intake box around the pickup tube with flapper valves that let fuel into the box, and seal it (or slow it down) going out Link to comment Share on other sites More sharing options...
powerbookguy Posted June 8, 2009 Share Posted June 8, 2009 aside from potential clogging issues noted above does the foam work well? does it use much of the tank capacity if as many foam cubes as possible are fitted? i have the earlier tank design as well and a surge tank had been installed by a prior owner with a second fuel pump, filter and a myriad of fuel lines. it works fine but the secondary pump is very noisy and i am considering taking it out to simplify the setup and eliminate the noise. thoughts?

slngsht Posted June 8, 2009 Share Posted June 8, 2009 If you decide to use it, I have some Summit Racing foam that's still new in its plastic wrap. I'll sell it half price if you're interested as I am using a different tank design and don't plan on using it anymore. Link to comment Share on other sites More sharing options...

It is an "open cell" foam, meaning there is nothing there except the connecting walls of each little cell or bubble. These walls are open to each other, more like a spider web, which means the foam essentially doesn't take up any gasoline space. My fuel pump is a little noisy too, but it is a reassuring sound, as long as it's working the car is running. If your system works, remember "if it ain't broke, don't fix it" Link to comment Share on other sites More sharing options...
powderbrake Posted June 9, 2009 Share Posted June 9, 2009 (edited) Here is some info from another thread where WestTexasS2k told of his experience, and his solution. http://www.usa7s.com/vb/showthread.php?t=3770 Originally Posted by slngsht here is more specifics about the pickups I'm talking about http://www.autoperformanceengineering.com/html/pickups.html I used these screens on my first car when it was supercharged. I ran it for the first time at Run & Gun and only made it about 5 laps before I leaned out the engine and broke the spark plugs off that rapidly destroyed the aluminum cylinder walls on my engine. I am not sure I can trust these on a FI car. We built a two tank system for Kevins car that has really worked well. We used a high volume low pressure pump to feed a 1 gallon tank that is connected to the fuel injection pump. This works very good as long as the fuel filter for the low volume pump doesnt clog.

RGTorque Posted June 9, 2009 Author Share Posted June 9, 2009 powderbrake, i seem to have the same tank but mounted differently. id love to see the inside of a tank with baffles and/or those valves/flaps/foam http://img269.imageshack.us/img269/9207/cimg2595resize.jpg Link to comment Share on other sites More sharing options...
powderbrake Posted June 10, 2009 Share Posted June 10, 2009 powderbrake, i seem to have the same tank but mounted differently. id love to see the inside of a tank with baffles and/or those valves/flaps/foam There seems to be no end to the variations on Ultralites, as to components and mountings. My tank is mounted on top of the crossbar that supports the diff, and the front of the tank rests on the diff housing as it exits the tunnel, with appropriate rubber cushioning. This gives me a deep "trunk" where I store my tonneau which I only use if I park it outside overnight or when it's going to rain. Link to comment Share on other sites More sharing options...
