Well, I did a little search and didn't quite find what I was looking for. When I start my car I can hear the pump prime and it fires right up. Now, It primes but it doesn't start right away and I have to let it go and let it prime again then it will fire up. Sound like a fuel pump to anyone else. I am thinking it is getting weak and it needs to be replaced. I was also looking for options into a new pump. I have a 351w that I plan on putting in down the road and I was think of getting a 255. Is that too much? should I just go with a 190? I know the return line will take what I don't use back but if I don't need it I won't get it. thanks in advance
