I'm around 90% complete with the EFI conversion. I think I've got all the details worked out (famous last words). I used a piece of steel brake line as a fuel line and now I'm thinking that it might be a problem. I'm afraid that it might rust. Any thoughts?
Why? I don't see anything particularly corrosive about gasoline. Stainless would have perhaps been better (but harder to fabricate). It could be okay for many years.
I've done a couple of Subaru engines for aircraft. The OEM fuel lines on those (the cross-over between the two banks among other things) are in steel. So yes, I agree, you'll be fine.... BTW: what kind of ECU are you using? Very interested in your project!! I've got this wild project forming in my head... a 400 with TWO EFI's. One for gas and one for Propane (which costs $ 3.50 per gallon up here, as opposed to $8.75 per gallon for gas). Propane burns hotter, so you really don't want to run the engine hard on propane (or risk burning the valves). So a exhaust gas temperature probe will sit in one of the headers and will trigger a switch-over from propane to gas EFI when exhaust temps get too high.... I can switch seamlessly between my two Electromotive ECU's on my aircraft, so why not on a 400?? Too many projects, too little time... sigh.... Hans
I'm using a MegaSquirt II. I mounted the fuel rails today. All looks good for a test start this week. As soon as I get some time I'll post pics.
All the fuel lines I have dealt with are steel not stainless... no worries, brake lines carry alot more pressure than the fuel lines. Rick
