While all bucketless fuel pump flows .2gpm more than a bucket design that retains the venturi it comes at a cost. Bucketless pumps should not be driven on tanks lower than ¼ full and should not be used for road course racing. This is not a disadvantage of only our bucketless system but is a disadvantage of all bucketless pump designs (or bucket designs which delete the venturi). If you do not plan on road course racing (not street racing) and are responsible at maintaining ¼ tank of fuel during spirited driving this is the pump for you.

*Note: To reach the advertised ability of these fuel pumps use of the Precision Raceworks in tank filter regulator assembly is required.

This is a true plug and play solution that anyone can install in their home garage and start taking advantage of the benefits right away.

Forget other "brands" this pump is king!

I needed to get a new LPFP to handle e85. I was keeping an eye on the F***** brand bucketless but I didn't like the bracket that much. The F***** Stage 2 bracket was fine, but when you go to Stage 3 and do dual bucketless it gets complex and fiddly where you have to assemble it inside the tank. Not cool.

So I found @BlackMarketParts and their bucketless. It had a much better design than xxxx. The pump bracket itself is extremely well thought out. No cotter pins holding the fuel level sender on, real screws here. Also, the pump outlet fitting is very nice and made install easier. Install itself is just like any bucketless...you can look up videos all over the place covering the install. I did and it made the actual event a non-event. Took about 20min to install it.

Before on 93 octane and 20psi of boost my LPFP would dip into the mid 40's during a pull. Now my pressure stays rock solid at 75psi even on e85. Not even stressing the pump a lil'bit.
