Are any of you guys running the Weldon pump controller? How do you like it? I picked one up when I saw it BNIB for about half price. I wanted to for my Magnafuel 4303 in order to keep the flow down while cruising.

What do people think about Ixizconcept fuel rail design ?

It has 3 ports and one of the can be used to link both rails together ?

And the return line is in the middle of rails.

Are there any benefits to run it like in the diagram below ?

Best bet for those would be having the return in the center and feeds on both ends.

I don't think it is a good idea to split the feed in 4 lines.

I am more curious about connecting both rails together with extra ports.

How would you ensure that there are no air bubbles in the system?
Four feeds and two returns actually sounds advantageous in that respect.

Not a good design imo, seems like a bottleneck having the return setup like that.

Look at how every fuel rail from, I4 to v8 is. Fuel in one end fuel out the other.

Series rail setups are the best way to insure you have the least amount vapor pockets.

I have run them both ways, series seems to have less issues especially when going to fill up and disturbing the vacuum created, and then having a problem starting the car.

just wanted to throw this out there. i installed a in tank bosch 044 to feed my surge tank and i used jbweld steel and regular on e85 and that stuff just melts away. i was trying to seal up the wiring to the bosch 044 in tank so my cabin wouldnt smell like gas and wasted a bunch of time testing both jbwelds, i dont know about regular gas but e85 for sure melts that stuff right off.

my solution was using atl wiring bulkhead from summit, part was like 21 dollars and it sealed my 12 guage wiring nice and tight.

An intank bosch 044 is so much overkill its not funny. What pump is pulling from the surge tank?

I'm not sure where you see 4 feeds but I see two feeds and two returns just like a normal parallel setup and a cross connect to balance pressure between the rails

Bosch 044 intank feeding 2L surge tank feeding 2x Bosch 044 pumps feeding id2000. All 3 Bosch pumps are hard wired to a relay to battery.

Bosch in tank is heating fuel more than needed IMO. A w255 is capable of flowing enough for 650whp for a surge tank. My system has proven that to 631. Other than that.. same as yours except I have the 255 and 2150s which are overkill but good price.

Personally I never liked surge tanks, If you think about it your 044 can easily pull more fuel then the intank pump can supply.

Is that the Jay's racing 044? IIRC they flow a heck of a lot more then the normal bosch 044

Oh and did you notice you mounted this in a crush zone? very dangerous!

What pump do you have in the surge tank Bariga? ( Way I read it the 300 is in main fuel tank) What size line coming from the surge tank to fuel rails?

The 044 Can pull more fuel, but it also will return the unused fuel from the rails. Typically a surge tank isn't operating at any pressure, so the lift pump doesn't have to work that hard, somewhere north of 275 lph at 0psi, at 12volts for a W255. I don't think you'll have to worry about it with your build Bariga. Some time attack cars where they're on the gas hard would need a bigger lift pump, but I think the serious cars run straight up fuel cells anyways. the 300 you have in tank would be more than enough.

My fuel system, as mentioned above made 631 with 1 W255 lifter and 2 044s at bottom Y'd together.

He suggested to have feed on both ends of the rails. Two end ports in each rail makes four ports for feeding. That means splitting the feed line to 4.

Maybe i misunderstood what he meant.

Layvon does the intank pump runs off fuel pump controller?

my first idea for my new fuel system, my plan as of now consists of the 300SX FMW Turbo on Full Race Twin Scroll Kit, i am new to the fuel system side, is this overkill or just right?

thanks

About right. You probably only need a -8 feed line if your going with a -6 return

Alright fuel gurus, take a look at my electrical design for retaining stock PWM pump operation and direct battery connection, I don't want my pump screaming at 100% all the time so this is my solution. Thanks to rocketperson7 for electrical assistance.
