OBS / First Gen 7.3 PowerStroke fuel schematics
Hi friends,
I'm in the middle of installing a GreaseCar system on my 1997 F-350, which has the 7.3L PowerStroke.
I created some schematics for the stock fuel system and a two-valve GreaseCar setup, and thought I would share in the hope that they'll help someone.

I have 135,000 miles on a greasecar system. If you are not in South Florida, South Texas or Arizona, you will want to add a 20 plate flat plate heat exchanger after your greasecar filter.
There are tons of posts by me over the last 10 years on this forum about greasecar systems. My system has been modified many times. The only thing left that is original greasecar is the veggie filter heat exchanger and the copper in tank heat exchanger.

Is that because the Greasecar kit just doesn't get it hot enough before it hits the injectors? I've been getting a lot of black goop from my exhaust, and I was wondering if maybe that's because it's just not hot enough.

So one would think that it is unburnt fuel coming out of the tailpipe, but I have never seen that as "goo." Usually you would see white or black smoke.

Oh, I do see lots of white smoke when running WVO. A lot less when I'm running diesel.
I don't know a thing about FPHEs, so please forgive my ignorance -- I'm about to start learning all I can.
Two questions:
- Do you have any recommendations for brand of FPHE? There don't seem to be a lot of people selling them these days. Are the ones sold as beer chillers suitable for WVO, or does it need to be specifically designed for alternative fuels? And is more plates better? I see I can get 40, 50, or even 60 plate models.
- I was thinking of plumbing the FPHE *after* the fuel supply valve. In other words, whether I'm running on diesel fuel or WVO, the fuel is being heated by the FPHE right before it is sent to the lift pump and the injectors. Is there any reason not to heat the diesel fuel?

They are all the same. 20 plate is good enough.

Good to see anutha greaser keeping this section alive..Kirk is the man! I ran 4yrs/150k on my l99 with my own creation. Like Kirk, only thing left of greasecar/what i used was the tank, copper heat tube in the tank and their fpr..wish i still had that!...
As for the 203* tstat, i wouldnt. Using the stocker tstat, tapping into the coolant line from p/s heater hose, off the block, i see 235-250* from there..gauge temp pic to prove..your oil will get plenty warm with heat exchanger and tube in hose assy...
