i have a miss on the 4th injector and i found that there isn't enuff presure coming from the ip pump, is there anything i can do?

How have you determined that there is low pressure on one line? You could have a bad injector or clogged fuel filters.

yes i cracked the line when it was running and the presure is lower than the other lines, when i opened the 4th line the fuel came out of the bottom of the line, and when i opened the other 4 they shot out of the top of the line. any suggestions would be appreciated

also i just and replced the feul filters and the injectors are new.

I would poptest all injectors just because it is easy and cheep. if injectors are good problem will be in pump. If pump has over 1,00,000 miles while I had it off and on a test stand. I would have all seals and rubbers changed.

is it common for one line to be low on presure?

also how do you pop test the injectors?

If the injector isn't getting proper pressure, it could pass the pop test. Some folks have a home made unit, others have them tested at a Bosch authorized shop.

and if the injector pop pressure is way low fuel will flow through it easy. Hence low line pressure.

Take them to Johndeer, International, Mercedes, or Cat dealer of your choice. Where do you live?

if the seals are bad in the ip would it give me low presure?

Hope Caterpillar is in your area. usually $5 to $10 per injector to test
