ABS part number confusion
Hello,
I'm trying desparetly to find a replacement ABS 4wabs ecu/pump.
1997 E150 V6.
Everybody seems to have a different part number, and then the sites contradict themselves in whether the part will work or not in my vehicle.
I tried salvage yards, used parts stores, ebay, but I cant get a straight answer.
My "ecu" or "2C219" has these numbers:
on a sticker: F7UA-2234-CC
on a bar-code: F7US-2C346-AC
V1A0C76 E150
Here are numbers that sites say that work: F8UZ-2C219-AA, UZ-2C219-FA, 2C286, 2C219, F00804447
Please help.

Looking for hydraulic diagram too
I found this thread and I have a 98 E-150 and can't find a diagram for the hydraulic lines on the ABS unit. I tried clicking on the links in the posts but they aren't working for me. What I could use is a diagram of which ports go to which wheel. I know the connections for the master cylinder but that mess of brake lines is is impossible to follow.
Any help would be appreciated.

Hydraulic Control Unit (HCU)
The anti-lock brake electronic control module then looks at that wheel again. If it is still decelerating, the anti-lock brake electronic control module pulses the normally closed outlet valve which decreases the pressure trapped in the line.

Sorry to bring up a long dead thread but I am having trouble figuring out how the HCU can reduce built up pressure in a line. I can see how it can interrupt the pressure by closing a valve, but when that valve opens back up, the line pressure is still there, so it can't bleed the pressure back into the feed lines. Does it funnel it back to the master cylinder via a separate line, or is there some sort of accumalator chamber that the HCU bleeds the pressure into?
Working on my sister's 2003 F-150 with its second new master cylinder, new vacuum booster and about 6 bleed jobs, to no avail. Pedal still goes to floor very easily.
Thanks for any advice.
