My SMC kit was the same. My theory is that without the filter in the line and the pump being smaller, the hose would either evaporate from heat easier or get pushed backwards through the pump under boost without spray. I could have replaced my pump with the one Razor sells and gotten by though, but I upgraded to his kit and the results have been impressive to say the least. Much more predictable and engine friendly delivery curve. Bight the bullet if you plan on keeping the car for a long time or if you plan on driving it a lot. I put 10k miles on my car every year from 35 degrees to over 100 degrees ambient and I need a system that I can trust 100% of the time. My SMC system did give me fits once in a while and the nozzle was filthy after I removed it with no line filter after 4 years and 40k miles. The Razor kit just works great and is made for our cars. I did put one on my Dad's TPI camaro though and that is working great too!
