Default We need something like this for the GM crowd...

So I have used these on roughly 20 cars - 03/04 Cobras, 05+ Mustangs, GT500's.

Even though the 03-04 Cobras have a twin pump setup from the factory, they use accordian style flex hose into a Y fitting to one outlet. A true Mickey mouse setup. This takes each feed from each pump into one or two outlets depending on your setup. They even machined a triple pump setup.

Many of them with twin Walbro GSS342 Pumps, Kenne Bell BAP, -10 Feed, Aeromotive 10/8/8 Y Block, -8 to the Rails, Weldon regulator, -6 Return. This setup has made over 1000 rwhp on 03-04 Cobras. If you wanted to stay returnless, they have hats for the GT supercar pumps.

But, this is a great and cost effective solution for the Cobra guys. Im hoping FORE starts making something like this for the GM guys. I wish someone would take the time and offer something other than a stupid sump.

03-04 Cobra
Triple


Dual


2005+
Pimp




Gangster.

Yeah its nice stuff. I don't know what that costs, but I bet that is part of the problem with most F-body guys being DIY guys they don't like to spend the money on stuff they can do themselves by moding the stock stuff, so most will do there own dual intank setups and save the cash etc... I mean APS offers a drop in for the F-bodies that is real nice and has seperate feeds, but its pricey etc...

I agree what's the price. It looks like really nice stuff though. Have you tried any of these on one of our tanks? I"m sure there would be a sender/depth issue

I remember seein something like this that was available for the F-Body's, it was the dual setup tho. Price was the issue for me. Lonnies dual setup that works just fine, or something like this that does the same thing for over twice the money.
It is a nice lookin piece tho.

Oh yeah, I am rocking 3 Walbro 340 pumps, set up sequentially. Works perfect, no mods to the opening. You have to put the sender arm on, once the assembly is in the hole, but no biggie. I talked with a place that does the triple pump setups for Vipers, I wanted them to just make the pump hanger part. They said it could be done, won't be cheap. I was ok with that, but after months, and no response. I modified the stock stuff to work.
The hat is modded as follows. I cuteas off all the stock lines except the rollover vent thing. I used 90* bulkhead fitting for -10 feed and -8 return. I got the 3 into 1 shower head block that MightyMouse shows in his dual pump writeup. I went ahead and ported it for better flow. I got the very expensive submersible SAE Gates fuel line to connect the pumps to the distribution block. I ran all new 10 gauge wires to the pumps. And then coated the whole top with a special Loctite epoxy to seal everything up. I cut the trap door in the floor to access it, the -10 sits slightly too tall, but I taped the access panel down with a slight bend to clear it. Each pump has its own dedicated power wire to the battery with fuse holder and relay.

No it is in the car. I was so focused to get it going, I didn't bother taking any pics. Maybe some day I will pull it out and snap a few.

Also Tiago is running three I think he had to put check valve in line if I remember correctly. I see you said they are running sequentially how do you have that set up?

Let me clarify my question. I was wondering if he is using the BS3 to activate them or a hobbs switch or a WOT switch etc... And if he is using any check valves?

First comes on like normal, second is activated via TPS from BS3, like 35% I think and the third comes on from the Eboost2 at 5psi of boost. No check valves. Base fuel pressure at 30 psi, and boost referenced from there. 160 lb. injectors and E85.

I run duals in-tank similar to the pics in the first post. I also don't have that stupid bucket to contend with, so mine are strapped together with a flex hose from each to a y-block and out to the feed. I also run a return using my evap line.

I've seen those for supras that hold three denso supra pumps. They were rather expensive to say the least.
