I have 93 Maxima SE.. I am getting 5mpg less now a days. I checked Oxygen sensor. I got CEL blinking if go over 2000RPM in diangostic mode 1. I guess Oxygen sensor is OK. Mileage on car 69K miles.

I would like to check the fuel pressure. I have the FSM which says pressure should be 35-45 psi depending on or off. Now I want to buy the pressure gague and check pressure my self. Now I found one on sears.com site..

But it is not same as one in FSM.. I mean the connections are kind of different..

Can some body tell me whether this is good enough..or you bought some thing different..?
Please let me know where you bought your fuel pressure gauge ?


Thanks:
