What would it take to get a MM in the 9's?

I modded a Division X 03/04 Cobra hat for my fuel system its a very nice piece , and makes the return setup very simple , i hate the idea of clamping two hot fuel pumps together to make a big heat pump.

What did you mod? It wasn't a drop- in piece?

Waste of money. Clamp pump 1 to pump 2. Unibit three holes for 2nd pump, return, and new racetronix harness if going return

If just adding a second pump and staying return less. Two clamps and a 5/16" wye fitting. Done. Although I still recommend a wiring and FPDM upgrade.

What harness is required? I already have dual GT pumps.
The plan is to do dual 340's, and return line. What exactly is needed to accomplish this? (Parts list)

Things I know I would need Pumps and a Regulator.

What fuel line/ fittings/ did you use?

OMG.. I already answered this for you in post 28, 30, & 32 in this same thread.

You sure ask a lot of questions for having a built car. LOL

Well I just went back and answered my own question, I didn't read well enough to see you gave me a whole list already. I just don't want to take any chances by changing a setup that already works, engines are expensive.

Just add bigger injectors. If I were you being that the car is built already I'd buy some ID1300 (pricey but last set of injectors you'll ever buy) and either dual 340s or the 13/14 GT500 (which also are dual and happen to be in the 2011+ 5.0) pumps and BAP. The larger injectors will allow you to keep base fuel pressure low this ends up helping out your pumps a lot and because of how large your injectors are they are still going to flow a crazy amount of fuel. If you want to keep your engine safe it should really be mandatory that you look into these I think at least http://www.jandssafeguard.com/VampirePage/Vampire.html

This would NEVER work in a returnless style setup , ID1300s are too big!

I didn't have the return style in mind when I wrote that. But am now also curious to why that wouldn't work with a return style Motown, is it simply because of what you said the injectors are too big?

I meant to say returnless setup , but ID1300s are too big of an injector unless you go E85
 
From what I have read from ID and people in the mustang world (specifically the 13/14 GT500's which normally keep the returnless setup and just add injectors and a BAP) these have excellent drivability may it be e85 or pump gas. Anyways the advice I gave him is the route I'll take when my time comes so we will see.

Mustangs and Marauders are very different as far as what works for one , but you will see.
