How did you connect the lines to your sending unit? I have been unsuccessful in locating an adapter to go from GM O ring fuel line to AN.
What you'll need is...

Thanks Scott and Matt.
I was just stuck on the Fuel sending unit. I didn't think they were metric.

Found this part number list for GM efi conversions on the internet, so it's got to be true...

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.

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
connects two male 3/8" Saginaw ends
Connector, fuel return, double female lines GM 15550219
connects two male 5/16" Saginaw ends
Short sections of line, approx2", with metric/quick connect
Pressure: GM#15694407 $10.55 list
15609225 short, straight $2.55
15609224 short, u shaped $3.25
15694408 $10.55

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
15567762 approx. 30"long $72 list
This line is used on '88 and '89 pickups. Looks nice and
it's flexible, but spendy.

rubber hoses
22527471 fuel feed, 1 male X 1 female 3/8" ID
22528623 fuel return 1male X 1 male 5/16" ID
10114736 return hose female X female 5/16" ID
10114709 feed hose female X female 3/8" ID
These are hoses which connect between the tank and the
lines. There are many different versions available, and
they are all model specific.

O rings
22514722 fuel feed
22516256 fuel ret.

Fuel Filters
25055052 or GF 481 (AC) standard efi filter
25055003 or GF 478 (AC) 1983 Camaro with Crossfire (5.0 "S"
engine) barbed hose end on inlet and 3/8 inv. flare on
GF626 has same fittings as GF481, is stainless steel (not
polished), and costs less! Fits 1995 Chevy pickup.
