Hey guys, I'm about to go buy some parts to fix this thing and would rather save the $25-40 on a repair manual. Any one have links to particular diagrams, pictures, manuals online that I could use to repair this car?

I've got a 1991 240 and am trying to find the fuel pressure regulator, but only using this picture Ive found, I still can't locate it. This is only one example.

 

the FPR is on the intake manifold attached to the fuel rail.

 

Wow, that's one CLEAN engine bay!

Sweet thanks, ya I feel like a dope. It was right in front of me when I was looking down underneath all that stuff for something near the transmission haha.

Thanks for the greenbooks link, though I did go ahead and buy a chiltons as a just in case. Figured better to be safer than sorrier.

Well, thus far I've replaced the Fuel Pump Relay, the 25amp, 16amp, and 8amp fuses associated with the fuel system and cleaned the contacts, and I've replaced the Fuel Pressure Regulator.

Turns out the main issue is actually the Mass Air Sensor which I have pulled completely out of the system and its running/idling way better but still not smooth. The relay improved the idle a bit, and the regulator was bad as I did smell fuel in the vacuum hose. After I replace the MAS I'm thinking the oxygen sensor.

This car is probably close to, if not 300k and has been partially underwater. I runs reliably with the MAS removed, or replaced, though it still idles and runs a bit rough. Can anyone suggest anything else to be changed aside from the oxygen sensor?
