E85 compatible bulkhead connectors for high volume fuel pumps. Made these for my Miata but they will work with other in-tank high performance fuel pumps, 25A.
$15 each, so $30 for a pair to run a fuel pump.
These seal at the tank and shaft unlike others. I want $15 for the double tank seal ones and $10 for the single inside tank seal ones. I plan to run one of each on my car to see if there is any advantage to the double seal.
