Here is a list of fuel line fittings, adapters, and some
other handy parts for GM EFI conversions.  This list is
primarily for Saginaw (metric O ring type) fittings. This is
updated to add part no's for Earl's fittings and Weatherhead
fittings.

_________________________________________________________________

Remember that part numbers and prices often change, that
parts are sometimes discontinued or replaced by "similar"
parts, and that any EFI conversion requires a certain amount
of ingenuity and flexibility.

Fuel feed lines in stock applications are typically 3/8"dia.
and return lines are typically 5/16" dia.
Some EFI conversions use Saginaw type line ends cut from
stock lines and attached to standard steel line with
*quality* compression fittings

These fittings have their roots in hydraulic applications,
and shops which make hydraulic hoses may be able to find
Saginaw ends to make custom lines.

Thanks to all who responded.  If anyone has part numbers or
info to add, please E-mail me and I will update this list
when there is enough new info. Thanks.
