I have put fuel pressure gauges on my car more in one year than in the other 8 years combined - all when I intro'd this combo unit onto my car. I could have just thrown the gauges on my car, and I should have. With the staggering number of check valve failures we are seeing, I felt that $20 to be 100% without a shadow of a doubt sure was a minimal investment.

Also, since Eddie wants to keep this pump for the conversion to EFI, I don't want him chasing a ghost with a possibly defective check valve. With this installed, I know my fuel pump and check valve are bulletproof. The rest of the fuel system will be leaving...
