Fuel Sump on a street car.....
on the bottom rear of the tank in the middle and mount the pump and filter on the frame or somewhere on the body, i know a few people have pics up can't find them right now though
Is there a reason why everyone does sumps. I was thinking about running -10 from the original fuel pump. just take the factory pump out and drill a bigger hole to fit -10 fitting and weld a pipe the size of -10 hose to get the fuel out of tank. to my knowledge that when fuel start flowing then it shouldnt matter as long as the pump is lower than the fitting where its getting fuel from. let me know what other people think
heres some pics from my setup and a long thread with some questions answered.https://honda-tech.com/zerothread?id=744585&page=2

Makes sure fuel is always at the pickup. Under hard accel, fuel likes to slosh around. Kinda the same principal with a baffled oil pan.
I'm not very good at explaining things

Not trying to hijack your thread, but does anyone use a surge tank in their fuel system? I'd like to learn more about these types of setups. I had a good picture of one in a supra but now I can't find it to save my life... here's an unfinished setup in a bimmer:

I can appreciate the use of a rear-mounted sump in a drag car, but the addition of a surge tank seems like it could be beneficial for cars that see lateral g's as well. Anyone have any input? Here are a few of the sites I found with yahoo:

http://www.jcperformance.com/fuel_tanks.htm

I was thinking along the lines of using a walbro gss341 in-tank pump routed to a surge tank in the trunk, from which fuel to the engine is fed via a walbro gsl392 inline pump, with return lines from both the fpr and surge tank leading back to the fuel tank. Just shooting out an idea since it is too damn late to think about anything else right now....

I am all about the surge tank.
I put one in the engine area.
It is a much better idea than a sump for a number of reasons, but primarily because it truly fixes the problem and you'll never have a fuel starvation issue, an you never have to worry about ground clearance.
That setup shown is very nice (but not too compact!).
All that rubber hose is not the best idea though- use aluminum hard line or earl's/aeromotive push-lok hose whenever possible.
Let me know if you have any questions about it....

Hey thanks - sorry I missed your reply - did you happen to have any pics of your under-hood setup? I'm interested in your mounting location as well as return line setup from the surge tank to the fuel tank. Thanks Ben!
