these are good , i was looking at them a while ago but went another way this should work well , i dont thing holly would show case something like this if it was shit TBH. this would work well i both your cars , 2 intank pumps and off you go , from memory i think it will take e85 and other fuel if you wish to run other fuels, ( best look it up tho to be sure ) i would run 2 pumps and Y piece welded on the bulk head, Y piece should be 6an x2 and 8 an on the top 8 an fuel lines to engine and back and use a 1 to 1 to regulate simple so you dont need to run the 2 pumps side by side , you can sit them sort of like one on top of each other, doing this will be easy to fit and take out when you need to , but as i said this would be what i would do , this way you get good pressure all the way when running 2 pumps, you should also have a look at the current that the 2 pumps will draw at full load , this will be a problem so you need thicker wires at least to the bulk head and then use a relay to turn the on i wouldnt use the zed wiring i would use the zed wiring as a trigger thats all just my 2 cen random image from the net, this works really good , http://dsportmag.com/word/wp-content/uploads/tech-multi-pump-pumps-05-000.jpg
Quick update on this. I did promise to do a write up and took pics and all but just haven't got around to it. Anyway my setup works perfectly on the track. I'm just running the two hydramats, one either side, and just the single factory pump. I'm able to suck right down to the last litre in the tank, no issues on cornering, and no issues with the single factory pump on E85 up to 19psi boost and 480rwhp. I ran this setup at Bathurst last year and have run it at several track days since. The surge tank is officially dead lol!
Good to hear, I made it to wakie again this week and used less than 50l out of the tank before getting surge in the fish hook, might have to invest in some hydramats in the future.
Yeah they work well. The one other thing I did was split the return so it feeds both sides of the tank, if either side does go dry before the other you'll start sucking air with a single pump setup. I just used the existing barbs on the top that are normally joined for the factory scavenging, and blocked off the barb that the return usually feeds.
Which hydramats did you buy? Looking at doing something about surge issues. Any pics of installation? Total price?
Thanks! Looking forward to it. I would rather do this than jumping straight into a surge setup. If i ever need to get the car rego inspected again its one less thing to worry about.
Good to hear it worked as advertised. Just a little heads up that i have picked up from other users. Dirt of any kind clogs up the hydramat in no time. So be carefull about what you fill it up with.
