I'd like to datalog fuel pressure (0 - 75psi), and I'm looking at using an oil pressure sender, based solely on price.
The autometer fuel pressure senders run around 100 bones and look pretty solidly constructed :
Your average 0 - 100 psi oil pressure sender looks a little less sturdy, but sell for around $30.:
I've never had an oil pressure sender fail, but I don't want to die a fiery death either. Would you go cheap, or what?
Me, I'd spend the extra 70 bucks, but if you didn't at least it would be a cheap fiery death.
Hay try it and let us all know how things work out. 
Seriously though, I would call / ask Bosch about this first The oil pressure sender may not be rated for ethanol/methanol that is in the fuel.
I'd be concerned that the guts of the $30 sender aren't compatible with gasoline and the gas will eventually eat through it causing a high pressure leak. 
Looking at the instructions for an Auto Meter 100 PSI fuel gauge, I'd lean toward one of them mounted to the firewall with a braided line going from the fuel rail to the sender. Plus I'd think the Auto Meter sender would be more accurate than the parts store piece. Give their tech line a call and see what they say. It's been a while since I've talked with them, but they were very helpful in the past.
We have used the cheaper sending units for sending units on diesel powered trucks for awhile but they never hold up because of some of the additives we use and gasoline will be much worse.
