Anyone did this? to make the pump run at a constant 12v? any improvements if so?

I did.
http://www.6gc.net/forums/index.php?showto...777&hl=fuel Its a good idea to do and I saw more consistent voltage through the efi system and the fuel pump circuit. Just make sure you use a higher quality fuse holder than the one I have pictured, because the one in the photos (purchased from walmart) ended up catching fire! I replaced it with a good quality radioshack fuse holder and never had a problem since. -------------------- 15PSI - 30MPG - Megasquirt Tuned
