I have a couple questions. One if you do have one pump die, will the pressure backfeed through the other pump? As long as there is some flow I would think it should keep the engine running but not anywhere near the pressure needed. And two if you don't just have an extra stock pump laying around how much is the cost of buying another stock pump and all the associated Y fittings and extra hose vs just buying a better single aftermarket pump and just having to run one line?

DIY Fuel System...now with pics
OKay, trying to gather up parts to build my fuel system to support the new injectors. Would this set-up work?
ITP in tank set-up then into a water seperator filter with a dual inlet/outlet head. Run two lines out of that pre filter, one to two seperate stock oem fuel pumps, then run the lines off those two pumps into a dual inlet/outlet filter head with a 2 mic filter. One line coming off each outlet feeding directly to each head.
So i would be running one pickup into the pre filter, then dualing everything thereafter to each head... Would that work, or would dumping both pumps back inot one post filter cause a rerstriction?
Any suggestions? Or ideas? Just trying to figure out the best way to do this

I have a question as well: Why do the OEM pump and all the Bosch inline pumps come with a check valve on the outlet side? I can guess that when you opened the filter housing to the atmosphere when draining the fuel system, it might siphon back into the tank rather than drain to the ground. Perhaps it is just to maintain prime in the system. Just curious?
I didn't run two lines clear to the motor. The dual pumps go back into a post filter, and from that post filter there is one line to the motor where it y's in ITP Diesel's fuel bowl delete to the heads.
As for the cost, the second pump cost me $160, the filter heads and filters cost another $70, and with all the fittings and hoses, 5/8" in tank pick-up, and bowl delete, I'm in the complete fuel system about $400.
Compared to a Fass system it is quite a bit less expensive. And the Fass set-up doesn't replace any of the pick-up or feed lines. When you consider the cost of one big aftermarket pump, such as the Aeromotive, this set-up is pretty cost efficient, and seems to work well.

actually i am pretty sure the 150/180 comes with a new pick up and lines. if not, the 1/2" pick up is an option. my 150/150 came with all new push-lok lines.I didn't run two lines clear to the motor.
