I did run into hard starting situation but for the remainder of the week I would pump the hand primer until hard and it would crank and studder.i could not have the one truck down that week and anyway the pump was not in town.i was Lucky no shavings got thru the fuel filter otherwise all the injectors would have been FUBAR. and thanks again to all of you who take the time to help a bulldog when it's sick.😁

Hello fellas. Quick update.Since replacing fuel pump truck has gained about 0.3 mpg .I guess the fuel pump is one of those things we have to throw a gauge in once in a while to make sure we are up to spec on pressure.for a sec I couldn't believe it but I started noticing that I could get a couple of extra loads with the same amount of fuel .😁

I believe these are it
-
I'm surprised truck ran at all with that kind of pump failure!
-

I'll let the images speak for themselves.truck is running like it should now

Yea pretty much.i will keep you guys updated on how things progress.

Mack wants 800$ plus and Pai is around 310$ and in town.
-
Besides the lower price that Pai offers , my closest mack dealership is out of the fuel pump I need and will take probably til mid next week to get.for 300 $ im willing to give up the warranty in order to forego the downtime from work waiting for mack to sell me a part that is severely marked up.
-
Yes it's about 300 dollars from m&d distributors.

I'm almost convinced that the pump is the culprit.removed hand primer pump and the fuel was glittery like if the shavings where glistening in the sun.i then removed the plug in front of engine where the pressure tester is used and the fuel is clean.makes me think that for now the debris is not getting past the secondary filter. Mack wants 800 plus for new pump.i have seen some aftermarket pumps like Pai.Is this a viable option or the mack brand is the way to go?please advise

Tank looked good and the primary filter did not have any shavings.

Truck is running much better today with the new filters.yet still falls dead on a pull especially above 1600rpm.im going to test fuel pressure and keep you all posted.
-
At first I thought that it could be the threaded tube in the filter mounting (see picture below) since in that truck it sometimes unscrews from pump and stays with filter.but threads seemed fine and would not account for the amount of shavings I saw.
-
Not to many unions in Texas I believe , but I have parked truck lately where I should not have.
-
Thanks.I will do that per mack service bulletin SB-224-004 .which you provided in a previous thread.

Hello guys.im beginning to suspect that my fuel pump is bad.last two days truck has had no power whatsoever.i changed fuel filters an hour ago thinking it may have been a bad fuel contamination.when I removed the filter that is attached to pump I was surprised to see a good amount of metal shavings.the driver side filter did not seem to have any shavings.please advice

I had to drop down from 425 to 385 because my tire would rub against draglink.

I believe the dimensions of rim is 22.5x12.25.they come in different offset . personally wouldn't get a rim with too much offset as it would defeat purpose of a the fender and throw mud back at you.

Need source for aftermarket exhaust manifold
R.E.D replied to Total Excavation's topic in Engine and Transmission
Changing over to a better flowing manifold reduces back pressure which increases engine performance and longevity. -
Update .truck ran the whole day without issues.last two hours of work a/c was on.
-
I checked for bolts but will recheck thoroughly tomorrow.the shroud support bracket I removed since the belt bent it the first time it came off.i need to hit that bracket with a torch in order to bend it back to place
