Perfect timing. I am getting ready to upgrade from the original Arrington hat, and this is a good refresher. i have avoided the Fore unit as I would like to keep a basket. It looks like their new hat may be the ticket for me.

Nice write up and great pics sir. Im running a Fore with 3 aeromotives. What do you think about their longevity, especially since Im running E85. ( I have -10 E85 safe fuel lines ) With Fore out of business for the time being, parts may be an issue. The pumps should be off the shelf parts I would assume.

I'm running Areo Motive fuel pumps in my car. They pump the shit out of the fuel. Pump and return a tank of gas 8 times a hour. Thats good and bad. It looks like that is part of my issue of the car dieing on me. One pump should have been put on a switch so it would only pump when in boost. Still looking into it but so far looks like the problem.

great info right there. much appreciated.
was trying to figure out how our system worked.

[MOHEMI]

You learn something new every day. Thanks! If you were going to add a maggie, vortech or even a STS TT system to a otherwise stock 6.1 would you make some changes to the stock fuel system?

Mike I only have two pumps in my car. I could just pull a fuse when I'm on a road trip. That would cure the fuel heat issue but if some smart ass wants to get honky with me then I would be screwed.

Wiring in a boost switch would fix it also. I haven't got the parts yet Josh said he is working on it.

Good luck Rob,I've Ben waiting for my hobs switch from josh for months now.. all three of my pumps are allways running right now. I don't see any isssues yet except when I run her for awhile,especially when its hot out,I seem to loose about 5 to 8 psi.I'm guessing that's cause the fuels getting hot. Thoughts mikey?

I'm not a fuel expert so.... oil looses pressure when hot. But maybe fuel is different?

[ScapeGoat]

[J-Z]

Isn't there oxygen molocules in fuel? So as the fuel gets hotter,the oxygen expands not alowing the pumps to push as much fuel as when cold.make sence? Maby someone can give a bereft explanation. I'm no Mr wizard..

oil has whats called viscosity, not the same as gasoline. Two different types of petroleum

fuel in your tank is also not reaching 200*

Yea probably not 200* but dam hot when it's getting ran through the fuel rails at a tank full every 8 minutes. That heats the shit out of it.

All I know is I have ran out of fuel every time I have drove the car more than a hour at a time. Pumps are still running I can hear them. The gauge says 0 psi leave the key on and you can hear the pumps start pumping fuel again then you can start it and go.

Happened at over 3/4 of a tank 1/2 tank and 1/4 tank also. I checked the tank for pressure it's not that. Thought maybe it wasn't venting properly.

I don't road trip much so it's not a huge inconvenience for me.

I built my custon fuel system with dual pumps and a return line. Since that time, its been driven 6hrs each way to the beach. 8hrs each way to southern GA. No pumps shutting off.Sounds to me like your pumps are seizing. You said you have aero pumps right? Have you looked in your tank? Look for fine black shit floating in the tank. Your pumps not pumping and registering 0 psi has nothing to do with them not being able to pump hot fuel. Pumps are designed to be in fuel pumping. The fact that your pumps STOP pumping should tell you something is wrong with them. And I would suggest fixing the problem before you destroy your engine you just payed for.

You can hear the pumps spinning away open up the trunk or from the car. Pull the fuse they stop. If they were locked up I shouldn't be able to hear them??
I'm all for getting it fixed but to this point don't know what it is if you say it's not hot fuel.

If there is debris's in the tank the pump would not start pumping fuel. If something gets caught in it it don't just leave it stays there till it gets removed.

I know your trying to help and I do appreciate it so don't take this as me not thinking your trying to help
