Review: Good Value. - Seem to be OK quality, but time will tell. No fitting instructions, but if you don't know how to fit, get a professional. Fitting was easy, although fiddly due to tight clearance on the mounting bolts. Action seems good, with a press and twist to engage. Cap seems to be waterproof, but again time will tell. Handled the starting load of a modern 2l marine diesel without an issue.
