I left the factory y-pipe to the carburetor for the fuel I just replace the rubber line that comes up from the intake manifold, as far as the posting about the temperature goes I have a 185 thermostat in there and it's brand new, I have never seen the temp gauge go above what my picture was except for one time when I had a radiator hose pop off but I did pull the thermostat housing and make sure that it didn't get stuck open, as far as lowering the fuel pump goes, that's not really an option in my situation. I do a lot of heavy 4-wheeling and if I hit a rock on it it's going to rip it off and then the engine will die. As far as the noise from the fuel pump is that normal? Also somebody mentioned replacing the filter inside the pump, I found one online with a part number 1640428530 from Parts. Nissan usa.com if anybody wants to look into that for me I would appreciate it to get some input as to whether or not it's the right part, also if somebody has an alternate part number for NAPA Auto Parts that would be even more appreciated because that would save me the shipping time

I never pinched off any fuel lines just to change the regular fuel filter, and no fuel leaked out of it. I also completely took the fuel pump off of the side of the frame to refit the new lines

Here's all the pictures I tried posting before, the last one is for you Mike, you mentioned these engines run hot, this is my normal operating temperature, is this normal? It seems pretty cool.

it doesn't happen from takeoff, it's when I'm driving normal highway speeds occasionally when I have to pull a long grade, I'll downshift from 5th to 4th and I'll get the RPM's up to about 4,500 and floor it to maintain Hill speed, about a quarter of a mile up the hill which is about a 6 to 7% grade it starts to bog out and then it gets worse about 4,000 RPMs to where I have to downshift to 3rd and maintain a 3000 RPM pull the rest of the way, I don't know what my speeds are as my speedometer cable broke when I was putting the new transmission in it slipped off the shaft that was going into the engine and the tranny drop down onto the speedometer cable and kinked it so I have no clue how fast I'm going I'm running stock gearing on 31 inch tall tires 3000 RPM I estimate 2 be about 55 miles per hour. The carburetor is newer than the rebuilt engine, the engine has 500 miles on it roughly and the carburetor has about 400 to 450, so I don't believe anything is worn out since then plus I only run 91 octane pump gas

My whole issue is when I'm at about 4,000 RPMs going uphill I still haven't been able to run it up the hill yet to see if the fuel filter fix the issue but after work today I'll be able to because I have to go up to the bigger town

Is the return line restriction that little pot looking thing that sits on top of the fuel tank? I took a picture of it the other day when I was changing my fuel filter because I didn't know what it was

The truck runs great the first video I posted was actually after the filter and the hose replacement but that's just a title driving it around this thing still sucking down feel like it's the thing to do though I didn't get a chance to run it up a hill and see if it dies out or not as far as the fuel return line goes, that's all original so up near the carburetor the fuel lines come in at an upside down y and I'm guessing the reason for that is any excess fuel that would be pump to the carburetor just gets fed right back to the fuel tank instead of constantly sitting there putting pressure on the seals in the carburetor as for my air filter I don't believe it's a washable reusable one but it doesn't have that many miles on it yet I haven't even gotten to my first oil change yet with this new engine

Sorry still trying to figure this pic thing out, the videos were easy

I'm using a mobile device though, not a computer, maybe I can get it to work differently if I load up the full website version or something, as for the fuel pump goes, I guess if it ain't broke don't fix it, it still gets fuel to the carburetor, I'll get an in line pressure tester one of these days and see how the fuel pressure looks

From the other video at the very beginning there was a clicking sound that sound is coming from my fuel pump, here is a close-up video of that as well, I don't know if it is normal or if I need to replace the fuel pump but it is working it pushes fuel to the carburetor

Mike, how were you able to post the picture instead of just the link?

This is the video of the whine sound, i went to different areas of the vehicle for different sound quality and it also illustrates how far away It can be heard, also to my ears it sounds like it has a slight stutter to the idle, but if it sounds normal let me know

Sorry I tried going to the how to post pictures topic listed here in the forums, but apparently it's not posting pictures it's just posting links
