Fuel Injection Throttle Body and Fuel Tank Suggestions...PLEASE!!!
« on: November 23, 2020 - 04:23:31 PM »
Greetings,

What fuel tank model and manufacturer do you recommend???

I am FINALLY getting back to playing with...and sinking more money into the Barracuda

It is a 1970 California car with a 340 and LA-727.

The engine currently has a 2000s vintage Holley ProJection 4Di throttle body style FI unit and the fuel system is currently routed via the following:

-Stock fuel pickup in the tank (this of course means there are no internal baffles)
-Rubber FI fuel line through an inline filter
-External inline fuel pump supplied by Holly in the ProJection kit
-Inline fuel filter
-Steel stock style 5/16 fuel lines running up the passenger side to the ProJection
-Steel stock style 5/16 vapor line running back down the passenger side to the gas tank
-The California style vapor gas tank system is removed (vapor tank in trunk is still there for looks)

The ProJection never really worked that good possibly because of the external fuel pump of my lack of tuning ability.

So I am interested in a throttle body fuel injector unit so what unit does the Collective believe is the best?

I need to go with a for-real submersed fuel pump.

So...what would you recommend for the correct system?

Should I run a 1/2 in fuel line only on the passenger side and delete the two fuel lines on the passenger side?

THANKS for your advice!!!

I highly recommend a Tanks Inc. tank, pump and pickup. I have used several and they are quality units. Which pump depends on how much HP you are making or intend to make.
