I just finished up this setup on my LT1 powered '63 Avanti.

Fortunately it wasn't a total nightmare. Avanti's already come equipped with a factory return line routed to the top of the fuel tank. They also have a big advantage over many makes in that their tanks are mounted behind the seat above the rear axle with the outlet at the bottom. This means gravity does most of the work -eliminating the need to fit an expensive in-tank fuel pump to suck the fuel out.

I mounted it all behind the drivers rear wheel so all I have to do is pull the wheel off for access. I also installed all new stainless lines -3/8" main and 5/16" return. Last thing to do is install an enertia/fuel shut off switch, but I can't find one for the life of me at my local auto parts store.

Anyone got a supplier?

Will,

you might want to take a look at the F/U I just posted to an old thread about using a VW fuel pump relay. I would think that you'd need to ask for an inertia switch by application, but a junkyard may be your best bet if you want an inertia switch, I just looked up one for my F*rd pickup on rockauto and it was almost $80!

Thanks Nate.

The Ford version with the reset button would do just fine.

I can order one for $100+ from my local guys, but thought that was kinda high.

I guess all the Street/Hot Rod guys are just using the OEM stuff and not some aftermarket switch.

All I know is Avanti's are already plenty flammable WITHOUT 90PSI of fuel spraying all over the place[:0]

I think the typical street rodder is likely just using a Bosch ice cube relay with an oil pressure switch. That's a perfectly valid way to do it but the VW thing to my mind is more elegant and takes the same amount of work to install. Also I don't like the oil pressure switch thing because if the switch fails, you're walking (until you pop the hood and manually ground the wire) - or, say, you lose your oil pressure in the fast lane of a crowded freeway - you may make the choice that you'd as soon blow your engine to get to a safe place to stop rather than have the car save itself only to be rear-ended!

How about an airbag under the tank to blow it clear of the crash scene? lol The oil pressure deal works pretty good and you can use the ballast resistor bypass on the ignition as a pump power supply to power up the pump during cranking. If the engine wants to start before the oil pressure is up, just use a timed relay triggered by the resistor bypass and set it for 5 seconds or so.

Well duh, finding one wouldn't have been so hard if I had only learned how to spell inertia properly [:I]

Had searched Ebay using improper spelling resulting in zero results. Re-searched with proper spelling and Bingo!!

Just hit the BIN on an OEM take off from a 2001 Mustang w/reset button for $20 shipping included.

Problem solved.

Thanks :)

That's a good tip- any time you do a search, eBay, Google, or elsewhere, double check the spelling of the search term.

Sometimes, in addition to my usual searches, I search Studebacker, Studbaker, Studabaker, etc. Most of the variations will get at least a few hits
