Competition Fuel Dump Valve?

[RyanB]

Now that I have figured out my twin setup I am going to start working out my fuel system. One item that is required it my class (equivelent to Super Street) is a Fuel Dump Valve. I have talked to a few people about them but havn't found a place to buy one! What I am looking for is a valve with an inlet atatched to my Haisley Aux pump and mechanical lift pump and then the standard outlet going to the injection pump but then has a mechanical dump valve that re-routes the fuel back into the return line to the tank.



I have heard that summit has these but the only thing I can find is a fuel shutoff valve!



I have heard that all of the pro-drag cars have to run a valve like this!



Can anyone tell me where to look!

Columbus diesel has them or you can try plumbing/hardware dealers.

Thanks guys!!!! don't know why but I didn't even bother looking at Jegs for them! Jegs doesn't give me the fitting size and I went on the Bary Grant site and can't find them. The other side Goodvibes Racing has ALOT of different valves and I think I will look into those.



Does anyone know what size of AN lines I should go with? I am thinking either 8 or 10-AN. Still have to get some fuel blocks also but thats another storry!

This is why you want to make sure you have a working air kill and a fuel dump. Teds pump screwed up (all the missing and popping) right at the beginning and started to run away, truck pulling is great!
