The fuel pressure regulator is responsible for the fuel pressure. Those stats on the pump just say what it’s capable of. The fuel pressure regulator will monitor the pressure correctly as it falls within the range on the pump’s details. I’d run that pump. Cheers Bennie

Two weeks ago we drove the Subarus out west. Somewhat last minute shift of plans to western AZ for our trip as that was the only part of the western US that had a decent weather forecast for the week. In retrospect we probably should have done the last week of April instead so we had more options but it worked out. Saturday morning Z and A and B met at my house at 8AM and we packed up and headed west. Got to a campground east of Denver and stayed the night. Not too much below freezing but we got a dusting of snow overnight. Sunday we kept driving and made it into Nevada and camped east of Vegas along Lake Mead, saw some donkeys on the way in, the first group of many we'd see that week. It was very windy that night. The ground was too hard to effectively stake in the tents so I put the loops around some large rocks but we didn't sleep well as the tent sounded like it was going to start ripping apart at times despite parking the car just upwind of it. Monday we took the scenic route to Hoover Dam including some unpaved trails. Continued into Arizona and started down some Massey trails. Saw a lot of Joshua trees in NW Arizona, some of them quite green. Started on Massey NW29. Massey NW28 was fairly high up in the mountains and we got snowed on again, this time in Arizona. Might have been graupel (small white pellets) but probably not hail. Excellent views. Saw an old Ford truck down the slope from the trail (middle of picture below) and hiked down to it. On the way we also saw a Saturn. Neither had batteries. The Ford's transmission tunnel had been cut out (appeared to be cut out where we found it, we saw at least one chunk of it laying on the ground). The transmission had been removed and presumably carried hundreds of feet either up or down a steep loose rocky grade. Some cool mine ruins at the end of the side trail. Definitely want to take this one clockwise (as viewed from above) which we fortunately did, there was a lot of rocky downhill in one section but the uphill in the direction we took wasn't bad. The next point of interest we saw were some murals that had been painted on rocks along the trail that were originally painted in the 1960s and then repainted early this century. That night we were trying to find a more sheltered spot from the wind but even a small pond at the bottom of a 100' deep mining pit was windy so we just camped out in a wash along Massey NW26. That night was windy too but not quite as bad as the previous. There were also donkeys nearby at night and in the morning. Tuesday the first trails, Massey NW26 and NW27, took us the rest of the way to Lake Mohave. Then back up into the mountains and more graupel. Saw another truck rolled down the slope off Massey NW19 trail. Drove to the remains of an old mine, probably the biggest ruins/tailings we saw that week. Got some more graupel and we were getting a bit hungry so I cooked some dino nuggets in an abandoned mining shack. A climbed the sandy tailings pile in the Forester. Numerous old cars half buried in gravel. Next we drove to Massey NW15 towards Alamo lake. It was getting late so we found a neat well used campsite under a couple big trees along Massey NW17 and finally slept well, basically no wind, A hammocked between the trees. In the morning we found an old overgrown truck bed, a homemade vault toilet, and an old well. Wednesday morning we drove to some other mine ruins and then down to Big Sandy River. Z briefly got the Impreza stuck but we were able to just jack the rear end back up out of the sand, put down sand ladders, and he drove out. We drove the rest of the way to Alamo Lake and then took Massey NW14 to a river crossing as there is a bridge for the gas pipeline but not for vehicles. I waded a few options and picked the one with multiple firmer crossings rather than one with a single long crossing and soft spot in the middle. Both cars drove through the various crossings/mudholes without incident and we celebrated with some PB&Js. It was very green along the river, not super surprising but not really what we'd expected driving in western Arizona. We took Massey NW12 to Swansea, perhaps the largest mine/ghost town ruins of the week, and spent a while exploring on foot. Drove down Massey NW13, a pretty fun wash, as close as possible to the Bill Williams river we'd crossed earlier and found the remains of the old pump house, more donkeys along the way. Took Massey NW6, crossed a canal and continued. Started getting dark so we found a spot off the main road to camp for the night. Thursday morning we visited more old mines along Massey NW1. Saw the Bouse fisherman, a bit disappointing honestly. Back to more old mines along Massey NW3 and a cave/arch at the top of a hill. Headed down to Quartzite for fuel on the way to Kofa NWR. When we got to the highway there was a sign to “wait for the pilot car” and the old man driving the minivan ahead of us got out and sat on his hood to smoke a cigarette. After a few minutes of impatiently waiting I noticed the powerline grade along the highway so we followed that for about five miles, crossing various washes along the way, until we'd passed the construction zone and got back on the highway. The Mobil gas station sold water for $0.25/gallon or $1 / 5 gallons (quarters only) so we got some water for drinking and rinsed off our heads. Best quarter I ever spent. The first trail we took in Kofa was Massey C2 up an extremely scenic wash/canyon. Small arch at the top of the canyon, skull rock, and a large balanced rock. You can no longer drive all the way through, you'd have to do a through hike, but we hiked from the end of the driving path up to the saddle to check out the view. Then we drove down Massey C1 (Palm Canyon trail) to hike back to get a view of the only native palm trees still growing in Arizona. It's a fairly arduous trek to actually hike up to them (start at the red post to the right) and it was getting dark so we hiked back to the cars to find a campsite. Found a decent one close to the intersection of Massey C3 and C4 where we wanted to start the next morning. Friday morning we drove south on Massey C4 to an old mining town/museum. A bit of a tourist trap but there were a lot of cool old things to see, plus they had flush toilets. We looped back to the highway and went back by the campsite to head east through the NWR on Massey C6 and C9. Where C3 meets C6 is the site of a large mine, fair amount of equipment/ruins and some tunnels to explore. We headed north out of the NWR on Massey C10, drove along the top of a dam, and drove down a bit of a fun pipeline grade. Crossed the interstate, continued north on Massey C11, and found a spot to camp next to a small old mine of course. Saturday morning we drove up to the highway and started heading home. Stayed in the same campground we had on the way out east of Denver. It was cold again, the small pond by our site was frozen in the morning, but no snow. Sunday we drove the rest of the way home. B's Forester drove about 4400 miles so the Impreza probably did about 4300. Forester needs a RF CV axle and one of his valve stems was leaking so we swapped on one of the spares in Iowa. Impreza needs a RF tie rod. Most disappointingly the coolant temperature crept up a few times on long slow uphill trails with the AC on and once in deep sand with the AC off. AC needs some work/tuning too, I might try running it at a lower voltage. It seemed to work fine last summer but it was mostly discharged before the trip and since I recharged it, the high and low pressure slowly diverge until it eventually shuts off and then it will cycle back on again. It does this every minute or so and you can feel it surging while driving. Not sure if it's fully charged. I'd forgotten how rocky a lot of the Arizona trails are. I'm not talking about challenging rock crawling, although there was some of that, rather many of the trails had a lot of 4-6” rocks that were just annoying and rattled the cars. For instance my glovebox latch came unscrewed near the end of the week. Haven't run into trails quite like that for such long distances in other states. A used the low range on the Impreza once at the top of a hill when he didn't have quite enough momentum to get to the top. Forester low range got used 5-10 times. Overall a good trip. No major problems, only got stuck twice briefly, saw some good scenery, hit some fun trails and had good weather. Sorry travelvw, not a lot of critters or carnage on this trip.

Battery voltage fluctuating with the turn signals is normal. The two 1156 bulbs draw about 5A when hot (~27W each), and at least double that cold, i.e. every time they blink on. The stock alternator is 55 or 60A iirc. You're pulling surges of a quarter of its high-rpm rating, and you're at idle (since you can hear the fuel pump) where it can barely keep up with the loads anyway. And when the voltage dips, the fuel pump slows down. A spark when connecting the battery is also 100% normal, and does not imply anything wrong, modified or otherwise. You're charging the capacitors in every electronic module, including the radio, ECU, fuel pump controller (I can't remember if that year has one or not), cruise control module, etc etc.
