I have an aeromotive a1000 external pump, and i've read that they get pretty hot and since it cycles fuel pretty fast that it can cause the fuel to heat up.

Is this something to worry about? When should i worry about it?

Does anyone monitor their fuel temps? Especially someone with an Aeromotive A1000.


I posted this in the single section because this is where most of the people with these setups usually are.

 

A lot of people just hang it off to the side, not even in the fuel rail when they upgrade from a stock FD secondary rail.
I personally made a small block that houses the FTS just because I didn’t like the idea of just flopping it out into the engine bay, and that it would be reading a higher temp than the fuel actually was. Not that it really matters because I think I remember hearing that it only has like 3 settings and they change it very insignificantly.

 

rotarypower- looks like you have some machining skills. Are those -6 o-ring boss ports you machined into the block? Looks good.

 

What kind of fuel temps are you seeing? and whats your setup?

I'm just wondering if its safe to run the car for 2+ hours with that big *** fuel pump?

 

Anyone?

 

side feed injectors would help cool the fuel but im sure you have 1600s

 

What is your logic behind that assumption?



I don’t have any logs of the temp, but I cant see that it would be a problem with the pump creating that much heat to affect anything, even on a detectable scale in performance or problems with detonation if that is what you are worried about. That pump would have to be horribly inefficient to transfer that much heat to the fuel for it to heat it up to any level that should be of concern.

And if you still feel like you want to do something about it, you can get a fuel cooling cell for like 20-30 bucks. Its just a finned extruded aluminum cell that you can mount anywhere.

 

Thanks rotarypower101, thats what i wanted to hear.

 

Got the same pump, so there is no need for worry? I am confused. Zinx are you going to be installing a fuel temp gauge or a fuel cooler?

 

If your worried about the sensor just sitting in there heat soaking from engine bay heat and changing your tuning all you need to do is set all your fuel temp correction factors to 0 and it wont change anything no matter what the temp is.

Actually i was orginally just worried about hot fuel in the tank and the pump overheating. Something along those lines. I may eventually install a fuel temp sensor, but i don't think theres much to worry about now.

 

What is the point of going through it all !!!! , if you install a sensor and gauge it would tell you that your fuel is hot and then what ?? , those guys with the power fc can see their temps , but what difference does it make to them when there isn't any way to controll your fuel temps . It"s a fact that the A 1000 heats up the fuel , I had one and I know , just feel the tank after a run.
I would concentrate more on getting the temps back down by simply installing a fuel cooler ( oil & trans . coolers work well) , somewhere in line , preferably on the pumps' dischsrge on the way to the injectors. That is a whole lot simpler and would actually make a bigger difference as cooler fuel makes a huge difference in performance.

 

You probably pick up alot of heat just from the rails being in the hot engine bay, with fuel constantly cycling. The gas tank vent valve on my FB was howling on a hot day recently (2 bosch pumps). I put a cooler in the return line - I don't want my gas evaporating that fast.
(Some Jaguars have a fuel cooler that uses the AC system to cool the fuel)
