There are pic here of the home made double pumper set up we put on trucks.

5678

The pumps are wired to run all the time we just upgrade to a -6 return line
so the fuel pressure can be controlled.

We just used a 3/8" brass TEE from the local parts store HELP section.

Simple and easy and cheap..

But if you do not plan to make more that 750hp we have tested the single
intake 255 walbro with a msd fuel pump booster and made 726hp on the engine
dyno with 84lbs injectors.

The y adapter was always the "expensive" part of the deal.

Wouldn't have to be billet... just something that would fit in there, and
wouldn't corrode in an alcohol environment.
(read: anodized, or stainless, or zinc-coated)

The thing that drove the billet "y"  was the form-factor issue. If a guy
were to discard everything below the plate that mounts to the top of the
tank, you'd be free of that restriction. You'd have to fab your own holder
from the plate to the pumps (a bent piece of bar stock), and you have to
stay within the total length dimension of the stock setup (or reasonably
close... within 1/2" or so)

Here's a few AN "Y" adapters:

The hot steup would be to discard the tube fittings at the plate for a set
of AN bulkheads, but that would add to the cost.
Twin HP 255s could feed *lots* of HP at a fairly reasonable cost (<$300, if
you use your old parts are are good at scrounging).

The electronics are pretty easy... 30A bosch relay, wire,  and a hobbs
switch.

Maybe we can goad Ron in to offering a parts kit....

Later,

While we are talking about fuel pumps...how hard would it be to fab up a 
double pumper setup? What would be needed?

Stock sending unit.
2 255 l/hr walbro's
Some sort of Y adapter to hook both pumps up to stock sending unit? 
Would it NEED to be billit?
Relay to kick second pump on

Anyone got a parts list from the old ATR double pumper?
