Meaning a certified ambulance?

There's no point with municipal or in house servicing and annual certifications. Big no bueno if ever caught. All that Medicaid theft would be given back in fines.

That being said it's the same as any other engine, can be done but for what purpose? I blew out more axles than I ever had an issue with emissions stuff on my rigs. We ran only Ford in my day, and I only worked in the field until the 6.7 came out

In many states, ambulances, firetrucks, etc, are exempt from emissions regulations. So depending on the location, it might be totally legal to delete the DPF. There are a number of good reasons to delete the DPF on an ambulance as well, depending on the drive cycles it sees. But I am with oscyjack, I am not sure it is necessary, as most of the time the emissions equipment works just fine.

If you are allowed to delete it, it should work just like on a pickup. Remove the parts, add in delete tubes / blocking plates, and flash a tune.

I've seen a handful of them deleted, couple 6.4's and early LMM's, small towns in certain states can get by with it for now but it's not worth the fines. Not to mention if/when the yuppies find out and try to file a class action suit against the ambulance squad for "medical problems from being around a dangerous vehicle"

Not only that but liability of life. Mechanical failures because of or just having changed configurations would leave the municipality on the hook if a failure led to delay of care.

A tune/delete will have little effect on response times. Downtime for maintenance is already covered in protocols and there is always mutual aid.

It'd be cool to bring it for the requisite truck on site for car shows and stuff, otherwise I think it's not worth the time.

IN MA all state diesels have to pass the same emissions test as a private rig

I noticed all of the older ones here are deleted and the new ones are not. The emergency vehicles here run on stop, too hot in the summer and too cold in the winter.

I was just wondering, have a squad down, chevy garage is saying the DPF is completely plugged and needs a new one for a cost of around 2500-3000 dollors, truck went into reduce power mode which I feel is a safety problem, and just thinking might be a better fix.

What are your emissions regs? Are you on the crew or in the shop?

That's WAY too much for a DPF even if you keep it in. Shit I'll send you mine for shipping cost and you can fab it to the van.

If you can Yank it legally, there wouldn't be a better time

There are DPF cleaning services, and a hillbilly carbon job works good too. Compressed air and a torch

yeah but it's a physical obstruction. It also could be a van conversion and in a private ambulance service the configuration is not always fed. Most of the fords I ran were all off the line chassis conversions from a normal rig
