'Evening, Gents.

Bought a '94 non-turbo 945 last week, flat-bedding it Home tomorrow afternoon.

Been parked indoors for four years, so I'm sure the fuel system is pretty nasty.

I'd like to disconnect the fuel line at the rail and extend a line off it into the storm drain which leads right into the Hudson River, but I live an hour from it so I'll have to use a drum instead and dispose of it at the town garage where they take all oils fuels and coolants. :)

Question I have is, how do I jump the circuit so I can power both pumps and empty the tank?
 
Not sure if you can jumper terminals 30 and 87/2 on the relay board for a 94? (the terminals are identified on the relay module pins. The 2 terminals are the nearest left and middle right pins on the relay board). I know that the 94s have a single intank pump. I know for older 7/9 cars this would work.
 
Jumper wire from 30 to 87/2 of the fuel pump relay socket to power up the pumps. Centason posted this at the same time I did. According to the wiring diagram this circuit is the same for 94 940.
 
Didya look and see if there was a drain? There was in my good friend Kevin Hawkinsons 740 wag-goon.

And you boys should note that everybody is Your-up uses the DIN numbers--and in that system 30 is direct to battery--always hot.
87 is "load' or consumer light horn, pump, wiper what-ever
15 is switched power--hot with key on.
86 is ground and 85 is "switch" (or those may be reversed--long day) and "switch" may be the wiper stalk or the cooling thermo-switch, or the hi/lo stalk

Ford BMW VW Saab All the Eye-ties and froggies, even loadsa merikun cars use those relays and it applies even on other things'''like coils and starters.
 
Just do what Lummert and Centason told you to do. That is exactly how it is done. The 94 940 has 2 pumps. It was 1995 when the 940 went to a single pump in the tank. There is no drain on a 940 gas tank, nor is there one on any of the later 740 gas tanks. Perhaps, real early 740s. All the later 7-9 series cars have plastic gas tanks.

Roger that. Thanks fellas. I'm sure I'll have an additional question or two when I'm able to get to this just to make sure I won't fry anything.
