It wasn't that hard to bend. I got a tube bender from UAP/NAPA for $10. I took them to an aircraft mechanic and had the ends flared to 37deg so they would be compatible with AN fittings. The hose sounds inviting and if designed for EFI then it should be fine but double check their claim that it is for EFI. The company that makes it should be able to provide some literature or a web site perhaps. One thing to keep in mind is that sooner or later you're going to have to go from that hose to a fuel rail and how you make that transition could make the decision for you. With AN lines, it's easy as NPT fittings are available.

It wasn't that hard to bend. I got a tube bender from UAP/NAPA for $10. I took them to an aircraft mechanic and had the ends flared to 37deg so they would be compatible with AN fittings. The hose sounds inviting and if designed for EFI then it should be fine but double check their claim that it is for EFI. The company that makes it should be able to provide some literature or a web site perhaps. One thing to keep in mind is that sooner or later you're going to have to go from that hose to a fuel rail and how you make that transition could make the decision for you. With AN lines, it's easy as NPT fittings are available. Are you making a fuel rail or using an OEM? cheers, jw ------------------------------ End of DIY_EFI Digest V4 #185 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
