<VV> Electric Fuel Pump Install?

[frankcb at aol.com]

Harry,
     You're correct about the inertia switch.  Ford had them on some of it's recent cars.  In fact I had to show them to some of my friends who had NO idea they existed or where they were on their Ford cars.  But if their Fords refused to restart after hitting a deep pothole or a relatively minor bump into something, they had to "reset" the button by pushing it in so the electric pump would work again.  I installed one in my Corsa turbo "just in case".  I also installed an electric switch on the dash so I could activate the pump BEFORE I tried to start the engine if the engine had not been run for some weeks.  Since the fuel/air mix on the turboVair is HORIZONTAL rather than VERTICAL as in UNboosted Vairs,  the PRE-activation of the pump helps in starting.
     .Notice just how MANY new modern cars today are available from the factory with TURBOCHARGERS.

An inertia switch is for shutting off the electric pump in the event of a crash. -----Original Message----- From: VirtualVairs [mailto:virtualvairs-bounces at corvair.org] On Behalf Of Tom Berg via VirtualVairs Sent: Tuesday, March 13, 2018 1:26 PM To: Arlette Pat & Carl Kelsen; Arlette Pat & Carl Kelsen via VirtualVairs; Virtualvairs Virtualvairs Subject: Re: <VV> Electric Fuel Pump Install? G'day, Carl... Can't help you with those diagrams because I never installed an electric fuel pump. They don't agree probably because they were individually conjured by suppliers of the individual parts, without much consideration for each other. BTW, what's an inertia switch for -- to measure vehicle movement? I did own a Corvan that had an electric fuel pump and an oil pressure shut off switch, and it was more trouble than it was worth. When the engine was hot, oil thinned and pressure dropped, and if it was a quart down, pressure dropped more and the switch shut off fuel and the engine quit, even if it was not in danger. I did have a friend install a simple on-line electric pump on a Rampside whose stock mechanical pump could not draw enough fuel to wet the carbs after the truck had been sitting a while. A toggle switch in the engine compartment activated this pump when needed. Otherwise it remained off because the mechanical pump was sufficient. My advice is to get a good mechanical pump and abandon the electric pump project. The mechanical vs. electric pump issue was debated in the mid '90s and it started with a bunch of faulty mechanical pumps getting onto the market. The "fix" was installing an electric pump. IMO, you will have less grief by using a good mechanical pump. And you'll conserve some previous hair! This is the cue for advocates of electric pumps to wade in. Be not confused by them!

Hopefully someone can help, because I am pulling what little hair I have left from frustration? I am experiencing considerably difficulty drawing up an electrical wiring diagram, that will agree with the (3) three sets of individual instructions supplied with each of the following Clarks Corvair supplied parts: 1. Electric Fuel Pump (Part No. C10295) 2. Oil Pressure Safety Switch 3. Inertia Safety Switch I firmly believe that others must have also been confused by these quite vague instructions or alternatively have unknowingly installed the two ‘safety switches’ incorrectly to the point that the safety switches might not work if the need came about. By carefully following the electrical instructions provided for the Electric Fuel Pump and the Oil Pressure safety switch I have produced what I believe is a compliant wiring diagram that follows the pump and oil pressure switch instructions. However, this diagram does not agree with the instructions that came with the Inertia safety switch and if I attempt to comply with the instructions for the Inertia switch, then my diagram no longer agrees with the instructions for the pump and oil pressure switches? I really want to install both switches but can’t determine the correct wiring for them. I have asked Clarks Corvair but have not yet had a reply. I firmly believe that a CLEAR wiring diagram showing the correct position for each component, switch, fuse etc., in the electrical circuit would resolve my concerns and perhaps more importantly prevent these switches from being incorrectly installed and as consequence being ‘useless’. I have extensively searched the internet but have found nothing. Lots on Electric Fuel Pumps and the switches but nothing on the correct way to install all three together. A good friend of mine (a retired Auto Electrician) after studying the original instructions and my wiring diagram, agrees that the original Clarks Corvair provided instructions simply don’t agree with each other and are at best “vague”. I will try to scan / attach a copy of my wiring diagram on this email. Has anyone got any advice on this issue or can anyone tell me where I am going wrong?
