CJ-7 Sending unit ('76 CJ-7)
 

Does anyone know of an alternate sending unit for the 15gal polyethylene gas
tank? Basically, what I need is a 3/8" fuel line from the tank to feed the
TPI I'm putting in but can't find a cross-reference on any of the Jeep
sites. 3/8" return's desired too but I can plumb the return back to the
feed before the tank if necessary with a "T" fitting.
Not concerned with the gauge since I'll get a gauge for the sender
resistance range.
Ideas for a "pusher" pump to prime the electric? Mechanical pump fed to
electric, FI pump?
P.S. I did find one site but they were using an in-tank pump and I've
already got all the pieces to plumb externally.

I'm presume you're using the GM two barrel throttle Port Injection
and computer, if that's so use GM's internal pump for it's designed
pressure. External forty pound pumps have a cooling problem.

Nope, nope. Tuned Port Injection with the raised plenum and ram air
tubes. I abandoned the idea of an in-tank pump in the beginning and already
have a Holley in-line pump. The TPI needed more pressure than the TBI. The
headache is that all my plumbing's 3/8" but the Jeep's got 5/16" suction and
1/4" return at the sending unit. So, before I try some "out of plane
maneuver", I thought I'd try and find out if sending units are somewhat
standardized and do it right.
I have one of the polyethylene 15gal tanks from 4WD Hardware, so, drilling
or welding's not an option.
Is it possible to cinch down a 3/8" hose on the 5/16" nipple? It's 1/16"
difference and all it has to do is hold suction. Of course, that makes me
want to avoid the option of T-ing the return line into the suction hose.
