Brand: Flo Fast Fluid Transfer Pumps

Fix your leaking Flo-Fast pump! This seal kit fits the original Flo Fast Fluid Transfer Pumps to seal the cranking shaft at the pump body. Updated kit now includes 2 narrow seals for better sealing. A seal removal tool is included.

Be sure to smear a little grease on the pump shaft and on each seal lip before installation.

Note: These rubber seals are used on the original Flo-Fast pumps only (Part Nos. 2577-005, -015, and -010) only. The Pro Series (2577-105, -115, and -110) use different seals.

did not do me any good


I installed the new seals, but the pump now does not work at all. I have bought another "pro" version, the money for the seals was just wasted.




Works like a Champ!!!


My friend races vintage formula ford with RMVR in Colorado. His old pump of 10+ years was worn to a point where it became hard to get it to pump. This one with the addition of the bearing on the off pump side with the 3rd impeller has got him back to a very trouble free fuel delivery system to his car. thank you, Rick Carson

Fixed a leaking pump


Had a Flo Fast pump leaking fuel around the handle and wanted to fix it myself. kit came with the necessary parts and detailed directions on how to disassemble and reassemble the pump. Replacement was quick and simple and the pump no longer leaks. I have purchased from Pegasus Racing several times, fast shipping products arrive as advertised.
