I'm traveling for work until Saturday, so I'll miss it. Happy to meet up on Sunday?

Given Caterham didn't start making the SV chassis until 2000, I was surprised how close the two cars are in many of the base dimensions. Also, I've got serious shop envy going on.

Do you need to try CSR seats in yours? I can swing by and let you try my squibs.

I completed the rewiring of the plug and install of the new MFRU and went for a multi-hour celebratory blat today.

The replacement relay and wiring harness parts arrived. I'm tracing out the wiring right now. It appears that the output from pin 4 goes to the 15amp fuse for the fuel pump, then to the fuel pump. As I'm disassembling the plug, it appears the crimp wasn't done well and it was slightly pushed back into the plug. My guess is that there was intermittent contact, which could lead to heat & spark.

Relay unit ordered through Rimmer Bros and a plug kit from another UK shop as I couldn't find a US shop with the wiring harness that would sell less than 2000 units or would take 4 months to arrive. So... I'm out for the upcoming 7 track day.

Thanks, I'd appreciate that! These are the only numbers I can find on the unit. BCS YWB 100970 4922 PBT-GF30 PA6-GF10/GB20

Well I found why I was struggling to debug the fuel pump in my CSR. According the the MFRU wiring diagram @Croc posted some time back, the MFRU fuel pump output pin burnt out. I'm not sure what caused this to go, I would have expected this to burn the fuse. So... Now to find where to order a replacement one of these.

Any idea what a set are going to run?

For those following along, my CSR had a Walbro grj235.

Well, shit. The fuel pump in my CSR doesn't have the same connections as the one from Rimmer Brother.

The connector has tabs on both sides that I couldn't see until I partially lifted the fuel pump out of the tank.

Working on replacing mine... How do you take this connector off? For context, it's the one circled on red on the second photo.

In the SCCA, it boils down to your tires. If you are running 200TW tires, XU. Otherwise, I think you're stuck in A-Mod due to the super charger. The current rules are specified here: https://cdn.connectsites.net/user_files/scca/downloads/000/078/494/2026 Solo Rulebook Feb.pdf?1770664112

@AeroCat Tell us about the Aero package on your other 7...

Yep. I found the most recent CSR fuel pump thread, as well as some of your previous posts that have additional information. I'll be ordering a replacement in the morning.

Sigh. Fuel pump woes at my first autocross with the 7. At least I'm within the Hagerty Drivers Club included flat bed towing range.

Reminds me of a song... It's like too much money, there's no such thing. It's like a girl too pretty with too much class. Being too lucky, a car too fast. No matter what they say, I've done, but I ain't never had too much fun.

I'm a fan of the long reach low profile jack linked above. IMO, it's a nicer and slightly lighter jack and like it better than their Low Profile Super Duty, which they were sued by SnapOn over.

If you've not done it before, for nuts & bolts related to suspension, I recommend torquing them then using a paint pen to mark the location. This gives you a quick visual reference for anything coming loose.

I checked mine, and it matches the owner's manual I have, which says a 15amp fuse for the fuel pump. I've had to replace other fuses, of which I now keep a suite of spares my traveling toolkit, it's been for shorts that I've found addressed. None for the fuel pump as of yet. I don't think I'd use an auto-reset on the fuel pump, but while you're tracking it down perhaps a Manual Reset fuse would save some frustration. I know my fuse block is rather annoying to interact with, given its position underneath the scuttle.

I bought a CTEK NXT5 in prepping to put in a LiFePO battery, and put my previously mostly dead Odyssey on it on a whim. I checked on it every day, and it kept saying either "checking" or the light that indicates the battery needs servicing. That was until today, when I went to buy said LiFePO. As I went out to the garage I noticed the CTEK said it was on "care" mode, and the battery held 13.5v steady. With my battery reinstalled, I went for a drive without issues. I'll be keeping an eye on this battery for the rest of the summer just in case, but for now, call me impressed. TIL, not all AGM aware maintainers are equal.

Or you can do what I do ... A 7 for the nice days and a Miata for the not as nice days. Such as when it's pouring down rain, or if either A/C or heat are needed.

I've experienced buying on BaT. Sellers make or break an auction more than how BaT rewrites your words. The advice, and more importantly what not to do from above, are spot on. My advice is to be engaged and forthcoming with answers as best you can, and if you have documentation, share it.

It's not me. While I've been out that way in my 7, it's been months.
