Subject: Megasquirt EFI conversion

This will probably take a year to complete, depends on if I meet & marry that rich super model, then I might write a check & have someone finish all my projects :-?

I'm still in the aquiring parts stage, have all physical car parts (318 intake manifold, bypass pipe & water neck) except the trigger wheel & sensor, GM weatherpak connectors, PVC wire,& megasquirt & stim board. I'm still undecided on ignition, seems the megasquirt gods are about to release hardware that would make coil on plug & sequential injection a much simpler task than it is now, & I have some crazy desire to do both. For now, I'll at least do EDIS, if nothing else, I can't see taking the time to install a megasquirt system & not take advantage of crank triggered ignition & ditching the distributor. The cam choice is still up in the air too, I have a nice close to 300 degree regrind cam, & some stock 264 cams too. I'm thinking turbo later after the megasquirt system is running good for 6 months. I may start with the 290 something regrind cam as N/A motor, then if I go turbo, I may go back to stock cam. With fuel at 4.09 for premium, I might use a 320i 1.8 ltr block I have. So a few options yet to be decided on.

Today I got my fuel sock extender made, PVC electrical conduit, cost 1.09 at hdwe store, cut the end off that's expanded to mate with another stick of conduit, walked next door to my neighbors guitar repair shop, borrowed the lathe & cut out just enough on the small end to make a tight fit. It is about 1" long. Now the gas guage will read empty when there is about 2 gallons in the tank, but I can draw gas all the way till empty. I will use MS 2, v 3.0 board, unless they release something newer before I buy.

Will PVC hold up to gasoline?

I'd say it will not last long. Design is nice but I'd consider some other material.

PVC I haven't tested it yet, but a quick google search found some positive results, some solvents do make PVC soft, but gasoline does not, check this out:

I'll throw a small chunk in a glass of gas at home tonite & measure it before & after
a few days soaking & do my own tests.
