Returnless fuel system


Im looking for the fastest and best way to empty ALL the fuel out of the tank. Im moving over to E85 and I need to get my piss gas out of the tank. Some people are stating (pull the fuel line and run the tank dry.) But I pulled the fuel that runs from the fuel rail to right below the block and nothing would come out. I would need to put the key into the acc spot to get the fuel pump to prime and then I got a lil gas but them it stops. How should I go about getting the fuel out????

 

if all else fails pull the fuel filter and pump out (move to the side) and use a hose with a hand pump to syphon the fuel out that way. you can get a little pump and hose for 5-10 dollars at an auto part store.

 

What tuning system are you using? If you have AEM setup the fuel pump as a generic output and turn it on 100% of the time when ignition is on. Then pull your fuel line and drain.

 

I have Hondata flash pro. I'm trying not to pull the pump. Anyone know if I can run a + wire to the pump so it will run with the car off?

 

I just ran it to 0 bars and then used the fuel pump priming to pump it out. Took awhile and many key turns, but it worked...

 

wow...Im glad I know have a return type system it only takes ~10 mins total to swap from 93 to 104

 

I would do yourself a favor, and put your pump on a relay, many how-to's posted here.

Then, it's just a matter of jumping a wire from that relay to your battery, jumper cable, or whatever to pump it out once you disconnect your fuel feed line on the rail.
