i had a prohopper setup on my ram, the only problem i had was the front cylinders leaking, i changed the seals out & put in viton o-rings & the solved the problem, i also work at a shop that sells hydraulic hoses & fittings, send me an email w/ the list of parts you need & i will price them for you,
jrivers@jgbhose.com usually all the fittings are JIC (flare) thread on the hoses & then pipe thread going into the accumulators & pumps & dumps, also you will probobly want to upgrade to a better check valve, i suggest a parker square check valve, those work great & the little ones that come in the kit clog up very easy & will cause your car/truck to leak down when its lifted
