M543a2 blew a fuel line. Can't figure out how to access it

[bigmike]

Guys,
the flex line going from the T at the FDC, around the back of the FDC, to the right side of the IP head blew. I struggled to disconnect it at the T but got it off. I can't get to the fitting on the right side off of the IP. Any tips or tricks please? The fitting is the copper colored one in the center of the picture.

I would like to see a pic sideways with how much room but. Wash down the head with brake cleaner cut off the plastic line at the fitting and unscrew the fitting from the head maybe.
You need to bypass the FDC so just install synflex push fitting at the head and one at the final fuel filter run new line.

A picture from the side is tough because of the giant power steering unit. Also, the wrecker fenders are taller so you don't have access to the side of the motor. Unfortunately, It's nothing like my deuce .
I washed everything down. Got it.
I even thought about cutting the line so I can maybe get a socket on it.
bypassing the FDC is an option if I can get the 45 degree fitting out of the side of the IP head.

Just upgrade the powersteering to a modern unit...

What James said, and maybe a crow's foot wrench to tighten a new one back on.

ETA: When helping a club member earlier in year rebuild his MF IP on his 5-ton tractor, we had to remove the P/S assembly and a few other things to get to all the hoses & connections. It figures that the least accessible hose/fitting will always be the one to blow out on you, and always at the worst time....

Pulled the front fender today. Got soldier B to help. Not too bad but I had to cut a few bolts that didn’t want to cooperate. I ended up putting in new fittings, bypassed the FDC, and went with std fuel line pressed onto barbed fittings with hose clamps. No leaks after start up. Next step is to re-assemble everything. Will post pics tomorrow.

Here are a couple pics. One pic of fender removed...not fun...second pic is the new plumbing.

I think Synflex would have been a better choice.

Napa didn't have the diesel fuel line. Only air.

That's what I use air line and a push lock Synflex fitting just about the same that was on there. Easy to hook up in a tight area. Also I don't use hose clamps with barb fittings as it can cut into the line.

Per synflex site, air line won’t hold up against diesel which is why they make diesel line.
none the less, put the fender back on. No issues and I’m back in business.

This is the only sight that had the most info. Looks like there Synflex fuel line is made for real high pressures in the thousands of pounds where we have just 70 pounds. The truck came with nylon line and I would bet the newer Synflex air line is even a better than are old stuff. One would think it might be a DOT thing to use the correct line for liability reasons for manufactures. I know marine engines must have USCG approved fuel lines and in most cases must be a hard line from the fuel pump to the engine. I would trust Synflex air line for diesel over rubber hose but what ever you are comfortable using. Good thing you got it fixed.http://www.eaton.com/ecm/groups/public/@pub/@eaton/@hyd/documents/content/pct_506328.pdf
