I am setting up a 12v Shurflo vacuum system - there is a lot of talk on here about the Shurflo 4088 and some about the 2088. Looks like the 4088 has 3.0 GPM and the 2088 has 3.5 GPM. Does the larger GPM of the 2088 mean it will pull more suction?
Is one of these pumps better? Or the 4048 (4.0 GPM) is double the price. Is is worth it that much more?
Thanks,
Jay
