I general I am happy with my system's ease of install, cost-to-value, and performance.
But it's not all been super-dooper.
1. The instructions were not nearly as specific as I would have liked. I was hoping they would include wiring diagrams and tell me exactly which wire to cut. Fortunately I had a friend and a shop manual who could help with that.
2. The electrical connects were the 'squeeze around the insulated wire and you splice in' type which seem like a bad idea.
3. they shorted me a relay ($5 and a trip to the store), no big deal.
4. Failed valve. This is the biggest problem, by far!!!
My supply valve which selects which tank to aspirate fuel from, got stuck in the open position. Typically with no power to the valve it suck diesel, and with power it sucks WVO. I guess it just malfunctioned and drained my WVO tank dry on a big trip. So I went under and manually switched the 2 hoses to backwards of how they should be so I could suck diesel to get where I was going.
5. Customer service. This is also a big problem. GFS doesn't answer the phone.
So I'm on vacation 700 miles away and can't drive home on WVO.
Eventually they sent me a new valve, but it was the wrong one
. So they overnighted me the right valve and I swapped out and drove home happy on WVO. It has been working fine ever since.
6. I know this is where a different brand of sytem would help, but my purge time is pretty long, about 1.5 minutes of "quick-purge." But short of doing things like adding a second fuel pump, bypassing the stock filter, or moving the location of the stock lift pump, it is what it is. My plan was to save on longer trips anyway, not just going around the corner.
1. I definately recommend not pouring oil. I was trying to avoid purchasing a transfer pump, but it's worth it. Mine was $179 and works great.
2. start collecting, settling, and filtering oil way before installing. I only had about 10 gal ready to use when I was done. It would have been nice to have more.
