I have a 79 series 2 esprit. I am close to done with the car, but have
2 bigh items coming up. I have weber 45 dcoe's that the previous owner
installed years ago. I rebuilt them with a kit, but there are no
velocity stacks. I know the engine was known as the torque less
wonder, But i dont know what Stacks i Shoudl run. My car has no
airbox, and i have a dreaded fear of the car catching fire due to
leaky carbs. So my question is what stacks should I run for the best
sound and least chance of leaks, or what air filters on the carbs for
the 907.
My 2nd question is I just installed 2 new fuel tanks for sps
sportscars. I have run the main line from both tanks from the fill
port to the tank and the bigger vent to the tanks as well as a new
style cross over pipe. I noticed on the drawings and on the filler
neck there is a very small port and it shows a hose going to an evap
tank. My car doesnt have this and I cannot find one on any vendor. DO
I need this or is there any other way to set something up with those
holes. As it is I am afraid gas will pour out that little port when I
do fill ups or put fumes into the engine bay.
My 3rd question is do they make a cover for the distributor so if gas
does leak it doesn't start a fire? I have seen rubber distributor
covers on other cars but cant find an option for our model of
distributor. If i went electronic distributor would it eliminate this
threat? I researched distributorless ignition and lotus pbc sells a
kit but its rather pricey but looks nice.

1. Sj Sportscars sells the trumpets for the S1/S2 with Dellorto carbs, for $18 each. These are also available for Dellorto suppliers as well, but price may vary greatly.
I am an Aeronautical Engineer, and did the calculations once on the effects of running without an airbox. The engine would be sucking in warm or hot air instead of the coolest air available. I wrote up my findings in a paper, which you can find on my web site:
www.holycows.net\Lotus
The airbox and back panel are available from SJ.
If you question my findings, please name all the cars that come from the factory without a cold air induction system. I'll wait. ?
3. I took a plastic container and sliced it vertically so that it slips over the distributor, which keeps fuel off of the distributor. Also make it a habit to turn the fuel pump on and check for leaks anytime that you work on anything back there, and on a regular basis
