94 e 350 7.3 fuel leak and no start

kellyf · August 14, 2017

Pulled the dog house on this on and line at left treat of engine leaking fuel. I think maybe this is a return line. Seemed a while back We got a set of fuel injector return lines which had a name. Also the flow plug module platic at the bottom is turning in to goo maybe from the fuel. I drove it for what was a trans shift concern, but it starting surging and barely made back to dealer and cut off and now a no start.we maybe have a working ngs. No turn signals ,wipers don't work and and light on with no speedometer. Thinking maybe that's a diff speed sensor. More fun for me!

the fuel leak appears to be from a a hose on the left back side of the block as viewed with the doghouse off. Is this a return line. I have heard of air intrustion causing no starts.is there a name for the fuel line return kit and if so does it include this line? I have little experience on older 7.3 engines with mechanical injector pumps. Any help apprieciated

Return line kit.

Dipaco makes some kits for the IDI's. They come complete, Hose, Caps, O-rings and clamps.

I keep 1 in stock as I have a couple of IDI's and I service a few.

Speaking about injector pump diesels. Does anyone have good source for clear hose for diagnosis?

The local ace hardware store has it on the roll. Not sure how well it holds up to fuel. Otherwise I can buy a blue colored see through line that is made for snowmobile carbs.

All hardware stores and Home Depot have vinyl hose on the shelf from 1/16" through 1 inch or bigger, $10-20 will get you a couple of feet of each size. Vinyl holds up for a while but will turn very hard and yellow with age. For short term testing it's fine.
