I've done a search and found that the Walbro unit is the most recommended. (255 liters/hr)

However, I cant get a Walbro for a few days.
I can get an updated turbo Transam fuel pump for $133 in two hours and have it installed tomorrow. Yes, I'm in a hurry.

Does anyone know what the flow rates are for the fuel pump in my 350 TPI (that I have) and the '89 turbo transam?

I need maybe about 10 to 20% more flow rate.
Will the turbo Transam pump be enough for me?

My stock fuel pump can not keep up with my fuel requirements (or it is slowly dieing).

Did your pump fail? I would actually put a second one in, its very easy, or if yours did fail, put a normal intank one in and a normal second inline one.
