Westech fuel pressure guage help...

[Devildog]

I Just installed Ray's bango bolts and did the electric fuel pressure sender at the same time, when I went to hook up the guage the instructions seem to be missing, can anyone PM or e-mail or post the fuel guage wiring instructions, Thanks in advance.

Green Wire goes direct between Pin # 2 on the gauge and 1 post on the sender. Black Wire goes direct between pin # 5 on the gauge and the remaining post on the sender. Red wire on the gauge goes to ignition switched 12V source. One of the wires for the liittle light can be grounded to pin # 5 on the gauge, the other goes to the dash light circut.



I also chose to ground the Black wire going between the sender & gauge to the chassis. Everything works fine.

I have the dual combo Westach fuel pressure gauge, so I'll probably have an extra pin, but here goes:



Gauge Pin 1: - To either post on Right Scale FP sender

Gauge Pin 3: - To either post on Left Scale FP sender

Gauge Pin 4: - to switched +12VDC

Gauge Pin 5: - to ground

Unused Post(s) on FP sender(s) - to ground



You can run a wire between Gauge Pin 5 and the Ground Post(s) on the FP sender(s), but if they both are well grounded, it's not an absolute requirement.



Light wire (either): - to switched +12VDC or instrument light tap (fuse in fuse box at left end of instrument panel), depending on whether or not you want to dim the gauge lights with the instrument panel lights



Remaining Light Wire: - to ground

Thanks for the help guys, the installation went well. At WOT the PSI drops to 5-6 ( marginable) at idle it at 14 PSI.
