I was going to say the same thing. I love pushlok style hose and fittings but they really do need a bit of flex so as not to eat themselves.
Sounds mean as hell!
Nice update.
One thing from my experience, keep a very careful eye on the short lines from the two pumps to the Y fitting.
Because the hose is stiff and the run is short with the push lock nipples taking up length you can see there is a tighter bend right at the nipple end on the Y fitting. This will tend to abrade the hose from the inside and it will split earlier than it would otherwise.
If you go to -an style you will lose the push lock nipple length for a longer hose length to have the bend in and there won't be the internal stress riser of the nipple against the short radius of the hose bend.
-edit- actually, this would be a prime place for steel hardline and tube nuts. I am not a fan of Aluminum because it fails with vibration and it is connected right to the pumps.
I lost a motor from this when I first did my '044 in-tank. The hose lasted about a mile and ofc failed under WOT. Your mileage may vary, but I would hate to see it fail ever.

Any worries about the loop of hose from the secondary rail to FPR looping over the turbo?
I can't tell how close it is, so its probably not a big deal.
is there any advantage to running the rails in parallel vs series?

EFR9180 26.5psi just shy of 750rwhp, E85. 2x 044 pumps running at 70psi base fuel pressure. 13.5v at the pumps. Genuine 044's are very hard to beat in terms of performance, reliability, life span, current draw, and cost.

Using a fuel log with the OEM 044 check valves may solve both potential problems.
There are tons available. Here is an example that would fit the way you currently have things routed.

As for parallel vs series, it isn't necessary to go parallel until very high horsepower levels. In theory it will flow more fuel.
Another issue with this Y setup is if you lose one pump the good pump will back feeds through the bad pump. Depending on what the fuel demands are one pump may be enough to save your motor even if it is lean but if it back feeds through the bad pump probably not.

Coming soon.
Headed out to drive and tune some today within the hour. Hopefully will have an update soon.

Was browsing through old threads and realized how long ago it was since this thread was updated!
I street tuned the car to ~21 lbs of boost on E85 and came to realize that the IWG EFR + turblown mini manifold wasn’t going to be anywhere near capable of hitting my 750rwhp target, so in normal fashion I decided to overhaul the car including several aspects of the fuel system. The fuel system discussed in this thread was installed in the car and successfully fed the semi peripheral motor and EFR 9180 combination without any hiccups for a few thousand miles to what I estimate to be 580-600hp on E85. I didn’t have any specific gripes about it, but did find a few things I could improve on to make it better.
Previously the pumps were fed from a single 10an sump outlet that was split to 8an lines to each pump. This always bothered me as it seemed like a suction head choke point, so I moved to independent 10an ptfe lines and added a second 100 micron Weldon fuel filter right off of the sump. Additionally, I re-installed the factory 044 check valves along with the high flow xrp check valve adapters and will be staging the pumps using the ECU to trigger the secondary on when needed. This should help keep fuel temps down and reduce the power draw on the vehicle during normal operation.
On the front end, I upgraded from the primaries from 2X ID1300’s to 2X ID2000’s for a grand total of 6 ID2000’s between the rails and in true test of patience hard-lined everything fuel and oil related in the engine bay. I plan on changing out the remaining aeroquip aqp push lock stuff to fragola pfte to match the sump to pump feeds in the back and believe that between the hardline engine bay and ptfe lines throughout the rest, the system should be bulletproof and set to last.
This time around the turbo will for certain be capable of hitting the 750hp mark, so we shall see how the fuel system holds. I’ve got a 3rd 044 sitting on the table in my garage should it be needed, but I’m expecting to crack the 750 on e85 with the first two with room to spare.

We'll see how it pans out. I'm not afraid to grenade a few as I've got a handful and can do the swap solo in a few hours.

I'll have to take a better one when I get home. Most of the in-process pics I have on my phone doesnt really show how it ended up as I redid every line no less than 5 times until I was happy with the final product. Here's a zoomed in picture of the one I poster earlier showing how it ended up. The DIY hardline job is no easy task if you are as **** as I am about things being perfect. Even now....I'm debating redoing a few lines.

Nice to see someone being methodical with plumbing.
what transmission pan do you have? Are you happy with it? Is the goopy scatter shield ok? I have an OS gearset which I would like to survive, I already have additional gearbox and diff mounts.

Its just regular ole summit racing aluminum fuel tube, sleeves and tube nuts. I would probably run a SS hardline if it were under the car, but in the engine bay I think workability takes precident as it was a beast of a job getting them all right with just the aluminum.

Update: finally wraping up the final bits of the most recent complete overhaul. Between the fueling demand of the semi peripheral port engine and the flow capability of this turbo system we're actually going to finally see how all of this planning stands up to the power we spec'd it for.

Stoked to see this bitch crack 800whp.

Since my last post I realized I had a bit more work to do than I thought and as per normal I've had little to no time for the car. I did find time the last 2 weekends to finish all the wiring and the car is now mechanically and electrically 100% sorted and prepped for fire. All thats left is adding coolant, oil and gas the loading up the new tune file and checking that all the new IOs read and function correctly and that nothing leaks when the fuel pumps pressurize the system, then its ready to fire. Hoping for sometime this week.

Seth, did you check your throttle cable tension? Looks loose as ****.
#125
Negative. I'm an on school mechanical cable guy. Dont get me wrong, I like the DBW stuff and would gladly go that route, but I came into this Ludwig harness at a good deal and the only thing about it not suited to my car/preference was the inclusion of OMP wiring, and lack of DBW wiring. I may could reconfigure or repin some stuff to get there, but it would be very difficult to bring myself to hack and mod a harness this nice. Id only really want DBW for use in idle control as the semi really needs a wider range than what the stock ISC can provide.
