Gang,
I have been following all the posted discussion the FAST, Holley and Powerjection and all seem closely related, with the most common being a return fuel line. I just seen MSD latest EFI kit in the fight but they are using a non return fuel line, I like that- has anyone used this yet and are there any opinions out there yet? Here is the WEB site:

Derek, It is showing prices now, Jegs and Summit both have them on their sites. Ak told told the lastest version of the Holly does'nt use a return line also, this are looking good for the old cars.

Pulse width modulated fuel pumps are getting more common. This allows the speed of the pump to vary to maintain the required fuel pressure.

They work pretty well & is the basis of pump control on the 2010 up Camaro, Cadillac CTSV etc.

A lot less complexity & plumbing needed.

I have been reading that Lonnis these pumps are becoming more commom. Holley added it to their EFI kit also.
