I know its easy to get way deep on the simplest of problems, and quickly over think things, I do it everyday.
I would never have changed a thing, it ran great, and it was one of the best sounding engines I have ever heard, that's how well it was running.
But the hairline crack, blew open to point it was dumping raw fuel all over the headers and ground, it had to go bye bye.
Now we all know its a small HSP 409, but, a good running. tuned engine sounds good, I have been up this side of the problem and down the other, and I am willing to bet all the money in Dons, wallet, that this fuel pump is going to fix the issue, right back to where it was running before.
But through the forum, I have learned how to go from a-z testing the entire fuel system, I feel comfortable enough to say, after testing these with the pressure gauge/PSI...........there is nothing, that is STANDARD, rated at 6.0 PSI, does not mean that's what its delivering, I never tested the original, I bought one that was supposed to fit, yada, yada yada. BUT I did test the last 2, both rated the same, both the very same part number/manufacture
The first one reading in the 20+ PSI, flooding carb, that was JUST running perfect, 10 minutes before (The leak/crack in the original was very sudden)
Changed to this one immediately.
Work through troubleshooting with Don and other members, take tests, go buy 2nd Fuel pump, a exact warranty replacement
This reads right at 6.0 PSI on start up and idle, you open the throttle up and you can watch the inline clear fuel filter go dry, and the fun ensues
just before it dies, pressure steadily drops under 3 PSI, under load. Now I don't own a dyno machine that can print out a graph or scale to read
But i do have a pretty darn good idea when I am out of fuel.
Now if I am wrong I will say, when it comes Wednesday. But I think with all I learned here, its been tested out and proven, of course its not on and running yet.
