My uncle thinks it needs a fuel injector its gettin good pressure but he says its running very rich and overloadin what brand injector you guys recommend?

 

Can you, or your relative, answer the above for us?

Meanwhile, the thing that's bothersome with all of this is that the problems you're having all seem to have started right after you repaired a return fuel line leak and replaced the fuel filter (unless I'm mistaken). Could be a coincidence, but you have to wonder if something didn't go right with those two repairs. Maybe the new fuel filter had some loose 'particles' in it that fouled the injection system? Or, is it possible that some rust or dirt, etc, made it's way into the system when you changed the fuel filter? Even the smallest bit of rust or dirt introduced downstream of the filter can foul the injection system.

 

Is there some kind of restriction in the return fuel line? This would cause fuel pressure to be high and engine to run rich. Also could cause it to leak somewhere, as you mentioned in your original problem. Also could damage the fuel pressure regulator. What I don't understand is your description of fuel pressure bouncing 40-80, and what you obtained for the fuel pressure testing (4 values) per the sticky at the top of the 2nd gen forum.

I would hate to replace the injection spider on a hunch. It's pretty expensive to play musical parts as a diagnostic strategy.

 

Yep, an ounce of diagnostics is worth a pound of dollar bills and parts. I'd pursue LesMyer's restricted fuel return line thoughts before you change out any more costly parts.

Another question would be; where in the fuel return system did you make the leak repairs?

 

With the new pump the fuel pressure is where its supposed to be he just said its still running rich we replaced the return line right there by the filter and my uncle thougt there was a restiction in return line so he ran a new return line with nylon fuel line

 

Scratch that last post i misunderstood him he said with it running its 90-100 lbs of pressure hes gonna do it with the key on not stsrted when he gets off work and ill let you guys know.we unhooked the return line with it running and only a couple drops came out but when we unhooked it on top of motor there was a ton of pressure.

 

We found a piece of the nylon hose in the elbow for the return line gonna fix that and hope thats the prob cause i bought that 315 dollar spider injector but we started traceing what we did first b4 puttin that on so i pray this will fix it and i can return thst part ill let ya know when we get it back together.
