AN hose barb, impossible to get? AN hose barb, impossible to get? protrim (Automotive) (OP) 27 Apr 05 06:59 I'm kind of frustrated. We are about to install a lot of Aeromotive fuel pumps on different cars. These fuel pumps has -AN fittings. But we want to use standard fuel rubber hoses with hose clamp and not the expensive steel hoses with AN fittings and everything. So I've found these that are suitable: http://www.behrents.com/Merchant2/4.19/merchant.mvc?Screen=CTGY&Store_Code=BPW&Category_Code=earls-straight-hosebarb-to-pipethread-adapters-aluBut none has -AN threads, only NPT. I've looked at Earl's, Aeroquip and others. Anyone has some tips?Can we use NPT pipe threads in -AN fittings?

A lot of people sell these fittings, check their dealers list. http://www.aeromotiveinc.com/products/view.phtml?f_cat=Fittings+%26+AdaptersNPT and AN don't mix.
