Construction and Road Equipment repair questions? Ask a mechanic ASAP
Thanks for asking your question. I will try and help you out.
There should be a valve at the return line on the secondary fuel filter housing. If your engine still has the recirculating line, the valve will need to be closed in order to prime the system.
Cat has advised to remove the line and cap off the ports it connects to as the recirculating line caused many more problems than it was worth.
Please reply back if you need more help or have more questions. I am happy to assist.
Let me see what I can find. Be back in a few minutes.
Here is a pick of the line near the transfer pump. IT runs up to the filter housing.
Let me know if you need more help. I am happy to assist.
Here is an image at the filter.
Does your engine have this Line or has it been removed?
You are very welcome my friend. I am happy I could help.
Ok sounds good. Keep me posted.
Yes that's it. It should run form there to the fuel pump. There should be a shut off valve at the top of the line. I would consider removing the line and plugging it off. It is not needed on the engine.
I think that's a good idea. Cap it and be done.
As far as loosing prime. The fuel pump and the fuel pressure regulator under neath the filter housing are designed to hold fuel in the system when the engine is off. If it's loosing prime. One of the two items are the cause. The regulator is underneath the filter housing. Looks like about a one inch plug.
