3.54 ~1600 rpm @ 60mph.

Hopefully it stays the same if it doesn't go up. I'm due here for new tires and I'm going to go with 33s instead of 35s. If I could, I would go with the stock rims and stock tires but unfortunately I don't have space for them at the moment. When I bought my truck, it came with 17x10 rims (maybe 17x9 but I can't remember) so I believe the smallest tire I can put on it is a 285/70-r17

What type of mpgs can I see with 7x0.010 if I have a light foot? I just ordered a set from DAP and am going to replace my 50hp injectors that I got years ago from diesel speed shop. The best fuel economy I have gotten with them lately is 18-19 hand calculated at the pump. I'm very very light on the throttle and usually the slowest on the road cruising at 60. I could have sworn that when I first got those that I hand calc'd near 20-21 but can't seem to get those figures anymore. Also had the pressures set to 310 bar at a local shop and they told me that 2 were starting to leak but that it shouldn't affect fuel economy and might only be a bit smokey on startup (which is what I was experiencing before). This is why I have chose the 7x0.010 injectors and to also have a little fun sometimes. I have a quadzilla adrenaline with v2 tuning and am planing to dial in those injectors really well for fuel economy. I'm going to start with mopar1973mans tune and adjust from there. Also, is there any timing difference between the stock 235 hp engine and the HO with the 17.2cr? I'm wondering if should adjust my timing a little lower or possibly higher to compensate. I also have the HO vp44 but I may go to a SO in the future to see if there will be any differences in fuel economy with the HO motor. Thanks guys!

UPDATE: The seal measurements are 8mm x 19mm x 7mm. Inner hole is 8mm, outside diameter is 19mm, and the width is 7mm. I got the wrong measurements before.

Thank you! Here are also some pics of the FRRP parts if anyone is interested

Does anyone also know the parts that are inside the pressure regulator? I think I may have lost a check ball when I was taking it apart but I am not sure. I know that there is definitely a spring in it but thats all I that I was paying attention to. Is there a check ball and a spacer looking thing in between the possible check ball and spring? Thanks in advance guys!

I think I found the right seals and bearings for the frrp. It looks likes it's a 8x22x7mm bearing and a 8x22x6.5mm seal. Might also be a 8x22x7mm but it's just a hair smaller. I'll be purchasing the bearings and seals then I'm gonna try to rebuild my old pump.

It might be about 2 weeks though as I'm a truck driver and am only home once every 2 weeks.
