We haven't had one leak yet!

The larger line pump is commanded on and only runs when needed too, so you're not constantly running and returning fuel with big tank pumps, which heats it up. If you ever want to remove it, take it out, leave the tank fitting in place and screw a couple of -10 and -8 caps on it and you're done.
It's posts like this that has me seriously considering driving from Texas to Ohio. I am very pleased to see that there is no longer a need to use methanol to offset fuel deficiencies!!

I'm eager to see a no methanol, 100% E85 Whipple dyno post. I'd also like to see the same test with a TVS2650, but that will have to wait a few more months.
