Here is a grab bag of fittings and hoses you can buy for DIY fuel system projects. Since we don't have use for these at this time, we are offering them at a special giveaway price. PLEASE BE AWARE THAT NONE WILL work without modification on any CIS fuel-injected engine. You can use some of these high-pressure hoses and fittings for other applications or for fuel testing other engines. NOTE. A number of these fittings will connect to the quick disconnect fitting on the CIS specific tester we sell below. FREE 140 PSI pressure gauge included as shown.
