Can someone point me to a website where I can order one quickly and the right size. I'm going to have 2 supra pumps going to the stock feed line and I need to get them to go together inside the tank.

Thank you, I appreciate the assistance

are you looking for an AN fitting or just a barbed end?

 

wont the stock lines just be a hender to the flow of twin supra pumps?

 

No I'm just looking for a Y with 3 barbed ends so I can attatch high pressure fuel injection hose from the pumps to 2 of them and then from the other barb to the outlet on top of the fuel pump assembly

and yeah I'm sure the stock hardline isn't gonna flow the best for those but I have been told (and a lot of **** that ive been told is ****) that the stock hardline flows ok for 550rwhp

You could run twin pumps via seperate lines and "Y" them after the rails so both rails get fed by different fuel pumps. One stock line is the same diameter of a -6 AN so running 2 out the fuel tank and running your own return is what you can do.

 

why not use the evap hose line for the return

 

You have the original fuel, original return line, and evap line. Two feed, and one return, obviously. Stock return is easiest to use for the 2 y-ed into 1 return since it's already routed into the tank for this. Then use the evap with high pressure fuel line to the other pump and the other rail. Make sure there is a FPR in there, usually you can Y the two fuel rail returns' into the fpr and then down the return line.

 

I used a plastic barbed Y that I found at a local motorcycle shop..It's specifically for fuel line splicing. It's 3/8 on all sides and works perfectly with the stock line. I've been using it for quite some time with no problems. I have extras if you want to try one. Shoot me an address and I'll get it in the mail.

keeping the charcoal canister....

plastic in the fuel tank. I dunno that just doesnt sound good to me even if they say the plastic thrives in gasoline. thanks for the offer though thats very cool of you

 

do you mean hinder?

 

I have the same setup. I used all Nos fittings, but it dropped the pump too low. Sow with the suggestion of Demetrios, I ran one -8 feed to the primaries from one pump and one -8 feed to the secondaries from the other pump. And a -8 return. This is safer also, because you'll know without a doubt if one or the other fails and you won't be needing a motor as a result either.

 

that's funny Ernie I thought I designed and built that fuel system...

 

My bad, sweetpea.

 

The pumps can also out work eachother, causing the one pump to almost cut off the other one. Running two feed lines is the way to go!

 

Why is using the stock return obviously easier to make the additional feed line out of??? No matter if you use the stock return or the stock evap line you still have to drill the tank lid to run a bulk head fitting and hook up either the pump or the return. However its the same amount of work to make the evap line a feed or return but if you make it a feed then you dont have to touch the return line. You can leave the return line alone. If you run the return as the feed the you have to cut off the long pipe so you can hook up the pump and then still do all the same stuff to the evap line so that it can be a return....which is drill the lid and install a bulk head fitting with barb end, then attach a hose/pipe to go to the bottom of the tank. If your going to do all that to the evap line you might as well hook a pump to it and not mess with the stock return line at all.

Long story short, I found it easier to use the evap line for a feed line and leave the stock return alone.

Sorry to bring this back but I was in a search.

I'm not exactly sure how the FD fuel system is set up but if two pumps are plumbed where their flow ultimately meets up, say the fuel rails, you will get a butting heads effect. To take full advantage of twin pumps, I think the best way is with a surge/catch tank. For example, a 255 lph pump in the fuel tank feeding into the top or side of a smaller 2-3 qt sealed aluminum surge tank. Plumb out of the bottom of that straight into a bigger external pump, then to the rails. This way the pumps aren't fighting each other and the flow won't have as many slight, frequent fluctuations.

Oh, returning fuel to the tank is a must on EFI cars to keep everything consistent.

 

got any pics of your install?

 

How about a pump to each rail then a Y to the return (the fpr can do this)

 

Mad_7tist found a metal Y out of cast aluminum and it works perfectly. The car was tuned by Steve Kan from Gotham and fuel pressure was through the roof. Just changing from my other pump to these twin supra pumps bumped the basepressure from 40 to 62psi.

We will take pictures of the setup soon to show everyone.

 

Awesome can't wait. Can you also post a link to the site where someone could buy this Y pipe you're speaking of?

 

I have the Barry Grant Y block it's made from aluminium and is compact also, also has a port for a fuel press.gauge if you wanted to fit one into it and two other holes for mounting it using bolts.
