New pump by tank

[egrout]

Installed new lift pump by my tank. With stock pump still in use. Since my truck is a 4x4 I needed to put the new pump some place other than the frame rail. I chose the under side of the truck bed. It is just about 18 inches away from the fuel tank pick up tube. In the future I will go directly to the fuel tank pick up tube. Cut stock line in front of tank, put a 30 micron back flow filter, new fuel line over frame to a Edelbrock 10 micron cleanable filter with cooling fins, to carter pump (7psi) to a Gulf coast toilet paper diesel fuel filter 1 micron (and only 20 cents to replace filter element) to the original fuel line with one more clear 30 micron back flow filter. I use my truck at work (construction) and I am compensated for using my truck with free fuel. Fuel is from a good supplier but our onsite fuel storage is old and questionable so I wanted to be sure of no contamination in my fuel system. Have valves set up to switch back to stock fuel line in case the new carter by the tank fails. I have a waterproof toggle switch by the new carter to turn off the pump by the tank and check stock lift pump pressure. Used the Cummins lift pump pigtail soldered on my workbench and made it an easy quick job for doing the wiring. Waiting on the new 0-30 Dipricol gauges and also Blair’s fuel test gauge. What do ya’ll think? TDR gave me almost all the info I needed for a good clean installation. On the new Duramax they have a small cooler 6x8 for the fuel but it is in front of the fuel tank right where it will get hit by rocks and stuff. Thank you all.

One things for sure, YOU HAVE ENOUGH FILTRATION . Sounds like you put alot into the install, I hope it works out for you. For some reason, that link didn't work for me ???

What's the rated flow of the Gulf coast filter ?

Thank you for fixing our post. I am not sure what flow rate the Gulf coast TP filter is. Received Blair’s fuel pressure gauge and could not get a reading from the VP 44 pump test port at the Schroeder valve. So I hooked it up to the test port on the stock pump test port. Both pumps running numbers are- 21 psi at ideal, 16 psi at 2200 rpm and 10 at WOT. All constant numbers. With the new lift pump by tank turned off numbers are- 16 psi at ideal 10 psi 2200 rpm and WOT is 7 psi. All numbers constant. Has any one found that their test port at the VP 44 would not read? May be the Schroeder valve is bad I will try and change the Schroeder valve from stock pump to VP 44. Our truck is a 2001. Thank you all for the help and Thank you Blair for the gauge.
