Its always best practice to replace these return line bolts and banjo seals during any LB7 fuel injector install. These bolts are notorious for stripping out during removal. Our DHD return line bolts provide a cost effective solution to replacement rather then $10 a bolt for OE.
These banjo style bolts secure the steel snake shaped return rail to fuel injector. Each kit includes 8 bolts, enough to service 1 LB7 Duramax.
