You can check for leaking injectors while the fuel filter is out. Fill it up over the pipe and disable the HFCM, fuel pump and Injectors. Then whip it over and watch for bubbles. Sometimes I use the fuel pump to fill it up just turn the key on and off real quick but that can make a mess if you aint quick.

 

How do you disable the HFCM, fuel pump, and injectors? And what do you mean by whip it over?

 

Pull the fuse cover under steering wheel with a flat blade screw driver turn the screws 1/4 of a turn. Pull fuses 20 FICM, 40 Fuel pump, and 103 PCM. You might need a fuse puller or needle nose pliers. Be sure there is fuel above the standpipe. If you want pull fuse 40 last and use the fuel pump momentarily to fill the fuel filter housing. Then have someone crank while you watch for bubbles. Do not crank on it for more than 10 seconds max. This is the easiest way to determine mechanical condition of injectors. What happens is combustion gas will come through the pintle seat and into the fuel gallery in the head and up into the filter housing.

 

Very interesting. I'll put this into my "learned something new today" file. I suppose if you watch carefully you can see which head is affected by watching which fuel line the bubbles come through.

 

Same here, never thought of that.

FANTASTIC POST. Can I add it to my "Troubleshooting a No-Start" thread (and reference you of course)?

 

As for the 36mm socket.......if you know any old VW bug mechanics they will have 1.

 

Great right up Mark...Thanks Again

 

ok, after reading some of these great tips I changed my filters for the 1st time (we don't put a lot of miles on ours but he works hard when he's working...).

1st my observations on changing the upper filter and then I'll go find the other thread for my tips on changing the lower filter/draining the HCFM (or is it HFCM?) -- (the two threads should be combined imho). The upper filter has sort of "splines" that mate with the "splines" in the housing around the fuel stand -- you may need to turn the filter a bit to get them to mate up -- I'm sure most will figure this out, but I thought I'd mention it.

In most cases I don't think you need to remove the fuel from the bowl unless you have a really dirty environment (dirty parts, dirty hands, what-have-you) as the fuel in the bowl has to go thru the filter to make it to the filter stand. Correct me if I've not got this fuel into the bowl and thru the filter into the stand thing right.

Good write up and I'll go find the other thread now...

I agree that you do not HAVE to remove the fuel before replacing the filter, but it is just more conservative that way. I remove it and put it back into the fuel tank.

I'm absolutely fine with being extra safe, Mark -- I guess I wasn't sure if I had the fuel flow from bowl->filter->fuel stand correct. Since I'm pretty **** about everything outside being clean when I did this, it just didn't seem to be as big a risk of contaminants getting thru. But I agree, careful and checking twice and thrice brings our space shuttle home...

 

Went to the Ford Stealer to get a fuel filter, found out they are holding out for $70!
Just called the IH dealer who wants $23 for their kit.

These are the International part numbers for their VT365 (6.0L) which fit our PSD's.

IH# 1847170c93 is the Fuel filter kit (2 filters)

IH# 1840752c91 is for the Oil Filter
- speaking of oil filters; FRAM, Motorcraft and IH are all the same Racor Element which should have the same patent #.

 

That number Sounds like a fuel filter for a 7.3 number 1843059c91 is the one for the 6.0

 

Also the Ford dealer wanted around $65 for the fuel filters, but I could get a discount if I bought a case (12) they would be $62
