The hose size is what I posted if that's your question.

well i called that guy but i need to know the thread size going into the pump.

 

[QUOTE=94 12valve;578699]All you will need is a T fitting that can be found anywhere fuel line is sold, 4ft of fuel line will be more than enough, some push lock fittings, metric allen wrench to remove the front plug, and another fuel fitting I used -8. I should have wrote the thread size down

here is my "T" fitting. the blue line is comming from my AD 150. The top black hose runs to where the fuel line normally feeds the ppump, the second line runs to the front plug that has been removed.

where did you get the front fitting for where the plug was.

 

I tried to post these last night but had a problem staying connected to the site.

Copied from CompD.

P-pump Fittings

M14 x 1.5 inlet and return

M18 x 1.5 front port


If you remove the helicoils from a P7100 case, you can use an M16x1.50 on the feed and return ports.
Be careful doing this.

 

We have done several trucks with this exact same dual feed setup. My 12 valve will have dual feed going to my 13mm pump also. It works fine so let the propaganda slide off your back and enjoy the constant steady unfaltering fuel pressure
