Had a couple drops of oil on the DCT so decided to pull it out and refresh all the seals and replace the filters.

The oil looked great. But the pressure filter area had some black stuff and shiny specs to wipe out and the mech over had some black sediment to wipe clean.

That part list was great! Only thing different now is the aluminum bolt kit has been updated and has a new part number.

The new bolts are steel I think. I don't have them in hand just yet.

That big fuel line is hanging down because it seems the darn thing is weeping fuel through it.

Came from Fuel it a while back when I installed the E85 sensor.

Spent last summer getting a fuel smell when the garage was kept closed but never could find an actual drip or smell out the likely location. While doing this work, we got a strong whiff near the plastic panel that covers the fuel lines and battery cables. No evidence of a leak but the hose reeks of fuel.

I always hear push lock hose will always weep e85 smell. They say its rated for it, but i dont trust it. May be beneficial to switch to a ptfe hose and regular an fittings.

Thanks. This is solid advice
No problem. I've had good experience with the jegs hose and fittings. And the price isnt bad at all! It is a little more of a pain to assemble than push-lok, so wear gloves to not get poked by the braid, but they'll hold more pressure and wont weep being ptfe with a stainless braided outer. Flex isnt as great being braided, but doing a feed from the hat to the rail isnt bad at all, few bends. The nice thing is too, if its too long, you can always unscrew, trim off and put back on.

Koul-tools makes a "funnel style" tool to help hold the fitting, and prevent poking yourself with the braid when doing fittings.

Lines Definitely worth looking into! Use for oil coolers, fuel, i plan on using it for my a/c since i believe the pressure rating is 1,500psi!

I tried to get a few pics showing the clearance.

The front is about even and the rear is the lowest part but still seems to be about the same as the front jack point.

I'll lower it to the ground soon and see how it looks before I fill it with oil
