Some of the DIY-EFI previous data on Fuel System parts

[Fran and Bud]

Recent posts about fuel system part numbers mentioned not being able to find
some earlier data.

FWIW the following is a collection of fuel system data that various list
members have posted at one time or another since I have been following the
list.  Sorry I don't have the data to credit the original DIY-EFI sources.
 
Fuel injection feed and return nut kit GM 1711798
thread sizes are 14mm X 1.5 and 16mm X 1.5

Connector, fuel feed, double female lines   GM 15544805

These fittings can easily be used with rubber line by using the quick
connect side as a barb.  Be sure to use quality clamps and hose rated for
appropriate pressures.

Stainless steel braided hose, feed and return
GM 15567762  approx. 30"long   $72 list
This line is used on '88 and '89 pickups.  Looks nice and it's flexible, but
spendy.

many different versions available, and they are all model specific.

Accel Saginaw parts:
JUMPER LINES:
"The kit consists of three 12" long, 3/8" diameter steel tubes and one 12"
long, 5/16" diameter steel tube with the Saginaw flare used in stock GM fuel
injection systems.  It allows direct connection to TPI fuel rails and a high
pressure fuel filter." (one end has Saginaw fitting, other end is
unfinished)
Jumper Line Kit:74731
3/8" Jumper Line Only:74731-A
5/16" Jumper Line Only:74731-B
HOSE BARB FITTING:
3/8 Saginaw/Hose Barb Fitting (2 ea):  74720-A (for both sides of a high
pressure fuel filter, e.g. ACGF481)
FUEL LINE FITTINGS:
"High quality aluminum fittings provide perfect fit to adapt GM fuel rails
(Saginaw) or high pressure fuel filters with Saginaw flares to AN-type
fittings."
Fuel Filter Fitting Kit: 3/8 Saginaw to 6AN (2 ea):74721
TPI Fuel Rail Fitting Kit: 3/8 Saginaw to 6AN (1 ea), 5/16
Saginaw to AN (1 ea): 74730
HIGH FLOW FUEL FILTER & PUMP FITTINGS:
"Anodized in a rich gold, these fittings allow the highestflowrate of any
Saginaw fitting available.  Complete with O-rings, these fittings now accept
#8AN fuel line."
High Flow Fuel Filter Fitting: 74743-H / High Flow Fuel Pump Fitting: 
74711-H Fuel Filter with 3/8 Saginaw provisions:
74720 (like GF481) These fittings adapt to a -6 AN line.

Finally found a local shop which stocks the whole Aeroquip line, not just
the metal-braid race stuff.   Not sure if anyone needs this info , but
here's pn's for what I used for going from frame-rail steel fuel line to
the fuel rail.  This is push-on rubber hose, no crimping rings or
compression fittings needed.  Rated for 300 psi.  Fittings are brass.  Also
available in -8 and -10.  

Hose, -6, Aeroquip PN 2556-6    
- -6 Hose to Male 3/8" inverted flare fitting PN 4740-6
- -6 Hose to Female 3/8" inverted flare fitting PN 4743-6

This is great stuff, and cheap too - hose $2.50/ft, fittings $3.25 each.

I have personally bought the SS flex hoses from local GM dealer and was very
satisfied. Find a dealer who will work with you on price.

Also ordered the Weatherhead Saginaw fittings and found them to be very poor
quality - had to find a friend with a small lathe to make them work as they
should. Even then they were not really right.

Often see Saginaw to AN fittings on ebay.

HTH,
Bud
