Can the Mechanical Fuel Pump on the 455 engine be replaced while the engine is in the coach or must the engine be pulled?

The tolerances look tight when looking at the Fuel Pump from underneath.

Pretty simple job from the bottom and top. No reason to pull the engine. Couple bolts and some hose clamps plus the hardline to the carb. I think I had to get at one or two of the bolts from the top, but most of the work was underneath. New one bolts in from reverse, though you may need to tap the ignition slightly to get the pump to line up correctly when reinserted.

If I can handle this job, and I did it twice, anyone can!


Thanks,

pretty easy job. especially with wheel well liners out.

what also makes it easier, is a wobbly extension.

the hard part is getting the hard line fuel line off. I bought a Jim bounds flexible fuel line. and just pulled the entire fuel pump out with the old hard line still attached. and once it got hung up, I cut the line.

When you pull the fuel pump, I like to remove the hold down bolts for the carb first. It makes pulling the fuel line easier -- then it is also easier to atach the fuel line loosely to the new fuel pump, then the carb upon re-install.

Oh Man,Yes,Rip out that wheel well and its 2 bolts and 2 hoses and $19.95 from your local parts store.That part alone is why I will never own another style of coach.

You MUST change the oil now as it is most likely FULL of gasoline!

Also use proper line wrenches on ALL fittings.That is part of the reason these other guys had trouble getting things loose I feel.
