<VV> Healthy pumps?

[Grant Young]

This has happened twice in the last month or so, and with no desire to start a long discussion on the virtues of various fuel pumps, I will simply share the concern, as it has cost me about $50 in postage to determine the cause. I had a couple of customer concerns about some newly rebuilt carbs dripping gas and running too rich. The problem was very bad at idle and annoying when driving, as the cars would often shut off and be hard to start when at a stop light, etc. I went through one pair at my expense and found no issues. I sent another customer a pair of replacement floats at my expense, but neither solution worked. I suggested a fuel pressure check might be in order, as both customers coincidentally had new replacement fuel pumps. To make a long expensive story short, both pumps were putting out too much pressure. One was replaced by the original pump (after trying a second new one) and another owner swapped the spring from the old pump to the new, and the problems were solved. Hhhhmmmmm?
