DIY lift pump plans anyone?

Are you guys cooling the FICM with returning fuel so you can run the pumps at full pressure?

Can you not run the pumps at full pressure if the ficm is on the supply side? Plus you wouldn't get as much cooling affect if it were on the return side.

Not on the lb7 and LLY you can't, the FICM freaks out with anything over 11 or 12 psi...

No you cant if you turn it up over 12 you get a fuel presure to high code.

blk smoke lb7, I was wondering if you wouldn't mind emailing me some photos of your setup that your making. I cant get the pictures to load on here thanks to being in Afghanistan. Also if you had to compare it to an airdog or fass system which would you prefer?
