hi guys, im looking for some advice since im redoing the fuelsetup on my FD.
Ported engine with a BW S363 and v-mount.
It has an xcessive LIM but im planing on keeping with 2x750cc in stock location for primaries and my 2x2000cc in the lim for secondarie.

I have a denso suprapump in the tank wich will feed a re-worx 1liter catchtank.


From that my plan is to run dual bosch 044s, one to the stock hardline and the other to the hardline for the coalcanister, they will feed each rail. and then via stock returnline to the catchtank...

Thoughts on this? Can I use dual inputs on my aem fuelpressregulator or will I have to T them first?


Is this outlet enough to feed my dualpumps? Via a Y-block or will I need to weld in one more so each pump has its own?

Thanks

 

I would do an outlet for each pump. You can use the two inputs on the regulator for each return. I assume you are setting up the rails in parallel?

 

Thanks. Yes i was planing on runing them paralel.
Hoping to reach somewhwere betwen 500 and 600 horses

 

OK now im having dual outlets welded in to the swirlpot.

Some further q:s

-Is it a bad idea staying with 2injectors in the xsessive LIM? Offcourse with plugs in the middle holes.

-Should I put some oneway-valves on the outputs of the pumps?

-Also im thinking about the placement of the pumps. Can I mount them on a higher location than the swirlpot?

Thanks guys

 

You can run either 2 or 4 injectors. Really depends what rails you have and how much fuel you need. I like to put some red locktite on the plugs.

Yes you should definitely run a check valve off of each pump. Otherwise the system takes forever to prime every time you start the car.

 

Well I have 2 rails. one for 4 injectors and one ffe for 2. Also have 2x2000cc injectors from my old setup so i guess ill stick to them.

But what do u think about mounting the pumps then? Swirlpot will be where the coalcanister is, and i was planing on bolting the pumps to the bottom of the bootfloor (above the diff)
