My "Special" 1999 Chevy Express 3500 Cutaway Mini Shuttle

Just picked up this 99 Chevy Express 3500 Mini Shuttle. Not sure what the final plans will be yet, but some sort of moto hauler/weekend RV'er.



72,000 miles
5.7L Chevy 350
15 passenger
New tires about 1000 miles ago, but at least 2 or 3 years ago so hoping they aren't cracking or anything from sitting.



Previous owner bought it from the Atlanta airport I believe and they had it converted to propane with a PoliAuto (?)(i.e. "Flux Capacitor") system of some sort, but it doesn't run like it's supposed to. He spent a bunch of money throwing parts at it to make it run better, but it still hesitates and sputters if you step on the gas too hard. If you baby it, she'll drive around town all day no problem. I think I'll look into converting it back to gas and ditch the propane altogether if I can't figure out what's wrong with it. Gas or propane it gets horrendous mileage anyway so I don't foresee it being a real cross country tourer or anything.


Will update as it moves along but there are a couple of other projects around the house that need attention before I dive into this thing headfirst. Cheers!

Poliauto

If there happens to be any "Poliauto" experts on here, any wisdom about that propane conversion system would be very much appreciated. In all my years of different Forums and searches, I've never found something so obscure that no one in the world seems to have used. Or I'm not looking in the right places.

And for the record, my wife hates it. (So far) She knows me well enough to expect it to sit in the driveway taking up space and pissing the neighbors off until I get time to work on it. What's even worse is that my in laws loved it when they came for our 2nd oldest's graduation earlier this summer.

What I was thinking might be cool is to kind of copy this design with 6 captains chairs, 3 on each side, facing forward, then bike/gear storage across the back.



Just not sure yet if I want to go more "people" seating for now, or go with less "seating", and more "RV", with bed, sink, fridge, shower, etc.

Curious if there's a better place to search for what all is involved with converting this back to gas? What(if anything) is different about an Express 3500 Cutaway vs. an Express 3500 standard van? (As far as fuel system goes).


Would "ideally" love a list of parts that I'll need to source to make sure I can round up any obscure parts that might have been removed as part of the propane conversion.



I'm assuming I'll need:
Fuel tank
Straps to secure it to bus

fuel pump
sending unit
filler neck
fuel filter

gas cap
Fuel lines if they happen to have been removed


What other little bits could potentially be missing? Pressure regulators, sensors? I've been searching for a nice parts diagram/microfiche online, but haven't found one yet for the exact set up I've got. Thanks.
