Just seeing if anyone has tried it and what regulator is being used. I don't plan on swapping this pump until I have lines to go with it but if my current pump is in fact dying its gonna have to go in.
 
I'm currently running it but not on E85. You can search and find others that have done some upgrades.
Jist of it off the top of my head

Swapped the return line to the vent from engine to hanger. Vent line is bigger than the factory return.

For return:
At engine bay for modded return Ran this fitting (http://www.discounthydraulichose.com/9069_JIC_x_Metric_90_p/9069.htm?1=1&CartID=0) into the reg and then hose over to factory vent line. Used compression fitting and barb on vent line.

At the tank I cut the necked down portion of the hanger vent line and then slid the hose up on the bigger part of the line that left over after the necked down part is gone and double clamped the hose.


For new vent
Then swapped the vent to the return from hanger to steel hard lines and form them to engine bay. I just disconnected the factory return line to the flex lines on drivers side of the engine bay down low by front of engine.

Pump wise I ordered from Amazon ...was the cheapest and I ordered the pump grommet from racetronix and it fit in min factory hanger pump mount. I spliced and drilled the hanger and epoxied the bigger wires in place and tied into the hotwire kit from caspers.

Of course use the proper size and type hoses for the new duty the new duty the lines are doing.

A year and no issues.

I will say if your vent line is rusty inside (mine wasn't) then of course you run the risk of have that rust scale go into the tank.
 
We run the 450 in our e85 car. We switched the lines around like turbo nasty stated
 
I tried but could not get pressure down it was up to like 70 lbs so I had to use 6an return from the regulator to tank and all is good now .
 
All my lines were replaced with classic tube reproductions so it should be clean but I can always run some solvent through it.

Which regulator are you guys using?
 
Ok. Got a 237 on the car now but I have an accufab also.

As far as using the vent for the return, can you guys tell me what I need for materials and maybe a pic for reference?
 
Do a search and study up on other posts. I went from the fitting put a link to to a barb fitting from Jegs IIRC and then I cut the lil bulge off the return line over where it 90s up by where the vapor canister was originally. Then I used a compression fitting to barb (got from local hard ware) and then used good fuel injection hose grade hose from the reg fitting to the vent line. Granted I dont run E 85 and if you do you need a hose that can handle it. I just bent the factory return line over slightly once I disconnected it from the regulator so its there just off to the side enough to clear and the same for the other end (flex line) of it just hanging there. I dont recall hose sizes and such.
 
I just got finished installing the new pump and hanger. Everything seems to be fine. I ended up just cutting a piece of hard return line off a junk car and had it bent and flared. The line was a bit short and I could only get one hose clamp on it but it should be fine since its the return. For the line I used Gates Barrier fuel injection hose. It's ran across the valve cover and loops through under the master cylinder, through the power steering reservoir bracket and down to the vent line with double clamps. I left the original return line in place and put a cap over it and plugged it at the tank. For the vent off the sending unit I just ran a hose out to the back end of the car and will put a filter on it whenever I get around to it.

Fired it up. DOnt see any leaks. Fuel pressure is fine and steady. Can't wait to get it out with a fresh tank of fuel and see what it does. Should be a big improvement over the reds xp pump.

With running the return line like I have, should heat be a factor? According to the website the hose is good to about 300*F. Thinking about getting some type of insulation over the hose until I get a stainless line for it.
