Routing my Return Lines

Postby rabiddan1 » Sat Jul 11, 2009 4:53 pm

I'm planning the routing for the Return lines on my system, but I've got a couple questions. First of all, I need to know where the return line on the IP starts. I've attempted to post a pic of the IP from Napa:

I'm guessing that the little port at the top of the Pump is the Return line

If I'm barking up the wrong tree from here, just let me know- and the rest of this isn't worth reading...

So, I've traced this line back to where it attaches to the Injectors, and it looks like this (existing return lines), and the proposed changes that I want to make:

Basically I want to take out the "T" which goes back to the tank, and un-plug one of the injector drains and use that as the "main" fuel return. This will save me a couple feet of hosing and some connectors & fittings, and will keep my engine compartment from looking like a bird's nest...

So is this a good idea?

for the SVO mode, the loop will tie into the vacuum side of the Lift Pump. I plan on switching to the SVO tank when I'm purging, and then when diesel starts flowing into the SVO tank, I'll know the fuel is out of the lines.

The IP in the picture appears to be a Stanadyne DB2 that is used for the Ford 6.9/ 7.3 IDI or Chevy 6.2 . Your proposed configuration is similar to the setup for my 1994 F240 7.3 IDI . However , I use a looped return for WVO .
