(ASMBMW4622) Fuel Level Sensor Lock Ring Tool - Compatible with BMW Models - Essential for Fuel System Repairs & Maintenance

Tried the old wood block and hammer method at first, couldn't get it tightened down enough.The generic locking ring from Oriely ended up breaking the seal on my fuel pump...Ordered a new seal and this product, haven't had a single problem since.A little high on the price, but you get what you pay for...Quality Product.After purchasing this I have lent it out to several German Car enthusiast in the area for repairs and maintenance, they're thrilled at the quality.
