Looking into multi-ports for feeds for my injection pump. Just read about 6 pages of this topic looking and from what I can come up with most people use the stock locations for 2 ports, OR use the stock feed, return as a feed, and the front port as their return. What do most people do in this position? Trying to get as much fuel as possible to it right now.

Thanks

I use the stock feed as a feed, the return as a return, and the front port as the secondary feed.
Works well with my 13mm pump.
 
If I'm not mistaken we used the same AN power steering fittings on both inlets.
 
Feed the stock feed port, feed the stock return, move the return to the front M18 x 1.50 port. Who's idea was it to feed the front port in the first place?

GunRacer1.. Mike Shannon I believe.

Trick question.......................................................


When and if i ever get my fuel system finished i will feed the front stock feed, the over flow, and front port. I may bump the over flow feed to the stock return feed looking at the scavenging system. But im not close to redoing my fuel system yet.
 
So how do the AN fittings seal? O-ring? Vs. the banjo fitting with the 2 washers?
 
I didnt use a banjo in the front or side, just for the return. For the front I have a 90° -8 fitting going into a -8 to 18X1.5, And for the side a straight -8 fitting going into a -8 to 14X1.5mm. Thats good for more fuel to the pump that i will ever be able to use I figure.
 
Is the 10mm allen plug on the front always so bloody tight? I'm not sure I'm going top be able to get it out without drilling it out(what a mess).
 
I used -6 AN 14mmx1.5 for my stuff as it was what I had from my Powerstroke system.

It took a 2' breaker bar on mine. IIRC, there was some kind of threadlock or sealer on the threads.
 
Yea it is that tight!

I use the front for feed along with the stock port and return out of the stock location.......seems to work for me. I did have a guy nicely argue with me at Denton the other day that I had air trapped in my pump doing it like this, I just figured it was no big deal with over 50psi of fuel pressure.......I might be costing myself power :bang

Lets go over everything that is inefficent on our trucks: Fuel system, air system(intercooler) and intake, cyl heads, heavy ass bottom ends, weights too much, too much drag and mass to move, power robbing inj pumps.......ok I'm done.
