Thanks for the info. Much appreciated. Yes, I would love to see some pics. Doesn't sound too difficult.

So, we finally got a chance to really test our fuel transfer pump solution.

IT WORKED AWESOME!!! :mrgreen:

We were able to run at VIR, faster than ever, no starvation and could run as low on fuel as we wanted (dcazin came in from one session almost on fumes).

So, starvation solved! Will try and post photos and maybe parts list of what we did. It was actually quite easy.

Only challenge now is really understanding how to measure fuel level remaining. Running the transfer pump seems to have the level sensors report artificially low levels so no good real feedback on when you are almost out. Can show E with light on and computer showing low or no miles dte while still having a quarter tank or so remaining. So know your fuel level and typical consumption rate.

One major problem solved :)

Excellent to hear guys! I will definitely be doing this to my car. That will help me save a ton of weight too.

The first time the digital speedometer started flashing - it freaked me out. Totally forgot about all that - :roll:

So I am about to do this to my car. It needs it badly. So the line u ran from drivers side pump to AN fitting on passenger side pump; where did it connect to on the drivers side pump? Also I assume u had to drill holes in the covers that go over the fuel pumps to run the line?

I am also thinking of just splicing the wiring of the new pump in with the old one. Does it have to be on a switch? I'm can't think of a reason it wouldn't work just running all the time. Its not adding fuel, its just moving it around so the thought of over flowing is negated. Please correct me if I'm wrong.

Sorry for so many questions. I have three days to get this done before my first race and I want to make sure I get it done right.

So the line that dumps the fuel back into the main pump...you say it dumps it into the bucket. Is this in the bottom of the tank where the baffles are or inside the fuel pump casing itself?

Pics would help greatly :mrgreen:

I think I got it figured out. Everything makes more sense, now that I see everything. I tore into everything today and I think I have just about everything I need. I am trying to find a quick connect though for the drivers side. I might just slide the hose on there and clamp it.

Well, I ran the car yesterday in comp school at Mid Ohio and I still hit fuel cut. It took a lot longer before I hit it, but I still did. I am wondering if I did something wrong.

Where does the fuel pump actually pick up fuel from? Also, my tube that I installed on the 6AN fitting on the passenger side, I have it dumping into what I think is the bucket you guys referred to. Its the bottom casing of the fuel pump assembly that the screen sits in. Is that correct. Any pics or insight you guys have would be greatly appreciated.
