I saw one advertised as standard equipment and wondered where mine might be. It could have saved me a lot of money and worry over the years. Is this some kind of aftermarket ?
Thanks,

Not offered on a 2001, or any If i can remember correctly.

Geno's Garage has them.

 

If you could post the link as to where you saw that I could possibly help understand what its for but SIX is correct in that there was no OEM factory fuel pressure light. There are aftermarket low pressure lights which you can install but the problem with them is they're set too low at only 5 psi. Meaning.....by the time the fuel pressure gets that low, there's problems. The only time this would be an acceptable warning device is to alert you to a fuel pump which quit altogether.
