When do you need a twin fuel pump?

The twin pump is $550 without pumps. It comes with various fittings and attachments required for installation. (A set of 3x 6AN in/out fittings, a 6AN o-ring plug for single hose output configuration, and a QD adapter for stock feed line as return line use).

There is a pump install kit option for $55. This includes new pump strainers and PTFE hoses and clamps for installing your pumps to the assembly. It is available in 3 different configurations depending on the pumps you want to install (they can have different hose barb diameters).

Then pumps are sold individually. I assume most people will want to use whatever pump they are already running and then acquire one more either through us or anywhere.

Also, an optional thing we will have on the site, are Holley Hydramats that you can attach to the bottom of one or both of the pumps. They are pretty expensive, like $160 or so each, so I dont expect them to be popular. So far the reports I am getting back is that the twin pump is not experiencing increased fuel slosh starvation issues over the stock pump setup. This is probably due to the pressure side jet-pump we made for these twin pumps. It is recovers ~85LPH of fuel from the driver side of the tank at idle and more when you go into boost. On top of that, We have a sheet metal baffle with trap doors designed for this twin pump. We have not made any yet, its a future option / add-on. That is what the 3 black screws with aluminum washers you see passing through the top will be for.

Availability.. I think there is one left here right now. I have materials on hand for a large production run and sometime in February we will have plenty of them on hand.

Running installing with our current S1 external filter fuel systems, you would use just one of the 2 6AN outputs. The twin pump output is a sort of manifold, so you get fuel from both pumps regardless of using one or the other or both of the outputs. We last second decided not to use a 8AN single output for the sake of installation. 8AN would not really clear the access panel cover. Also, many customers already struggle to get a 6AN hose between the tank and chassis. So our first fuel line upgrade kit for the twin pump (which will be part of our new S2 lineup coming this year) will be a twin 6AN output line kit that merges into the single 8AN inlet of the external filter we provide in our kits.
