I have carbon tillets with the thin pads and they are very comfortable. I don't have any other related medical issues- it's just in the 7. On a typical workday I will pee when I wake up at around 6AM, then have breakfast, including a cup of green tea. I don't pee again typically until noonish. On a Saturday trackday, I will wake up, not eat or drink anything, empty my bladder right before I leave in the 7 at 6AM, , then drive 1 to 1.5hrs to the track and my bladder is somehow BURSTING before I even arrive. Never had it in any other car (even other stiffly sprung cars). Pretty sure it's related to the vibration - certain frequencies of vibration are known to stimulate urine production/bladder activity, and this is even utilized as medical therapy. I've learned to adapt, but it is annoying, and I was just wondering if anyone else had the same effect.

Nobody else gets the piss shaken out of them in their 7? Maybe that's just the price of high spring rates.

Nope, not that bladder.

Talk amongst yourselves.

Cat is not a requirement for SB100 - only emissions requirement is a PCV.

Train horns are cool but you need compressed. In the bike world, the Stebel nautilus is pretty popular. Would probably work well on a 7.

I don't have IG either but I am able to view the video.

Interesting. I pulled the pump and gasket and replaced without apparent issue in June. Gasket was supple. No issues since then. Car is only 4 years old. But I will get another gasket to have on hand just in case.

Why is that? Do you recommend a new gasket every time a pump comes out/goes in, or because it's a new (potentially different) pump or what?

Ok so I decided to buy the bosch unit from this site: https://spareto.com/products/bosch-fuel-feed-unit/0-580-200-182 Listed as compatible with the Euro OEM part, and the one of the few/only retailers that will ship to USA. FYI shipping was 40Euros. Will update with results later.

Interesting when I pulled my pump for inspection it didn't appear it would hit bottom and I didn't feel any resistance when replacing it.

Best guess is BV619H307DD is a Euro-only part number. But cross-referencing to domestic part numbers seems impossible despite the last 2 hrs of my googling. I will either have to take a leap of faith and hope the domestic part works, or buy from Europe.

Amazon will not ship one to me. Looking at the design of the pump and "hanger" mechanism - it looks like the depth of the pump may be adjustable with the hanging rods. I assume if a pump I get is different depth than what I have, I can easily adjust it? Or is this depth fixed?

Amazon will not ship fuel pumps to CA for some reason. We have bizarre hazardous/banned materials laws here...

And obviously I have tried to find a source that lists a BV619H307DD compatible pump, but I cannot find a US source, and I am afraid of random ebay sellers selling unbranded stuff. If need be I will pay shipping/tariffs, as they're still much less than what Caterham is charging.

This is the only thing on rockauto that comes up for BV619... https://www.rockauto.com/en/moreinfo.php?pk=14260833&cc=0&pt=10147&jsn=10916 Not sure if the image is supposed to be representative, but the top of the housing and layout of connections looks different. For instance for a 2012+ focus, the Delphi FG1532 comes up, but the listed OEM compatibility does not match my pump: https://www.rockauto.com/en/moreinfo.php?pk=7333804&cc=1501060&pt=10147&jsn=10895

For some reason on rockauto, it does not show the pump part number I have. Looking at other sources, it shows my part number as being for a 2012 Focus. But then looking up 2012 focus on rockauto, it shows different part numbers, not the one I have.

Obviously I have searched for this information. The part number is on the top of my pump (bv61-9h307-dd). I didn't know if the internals specs or dimensions of the unit/float is different as used by Caterham. Hence my question... So.... can we confirm that the part is indeed an off-the-shelf Ford part without any modifications? Or are we just assuming?

Need to replace my fuel pump in my 2021 420R. I know it's a Ford pump but does anyone know if it's an off-the-shelf Ford part or is it specific spec for the 7? This is the unit that CC sells: https://caterhamparts.co.uk/pumps-senders/5501-fuel-pump.html It's out of stock and probably more expensive that buying it locally from my Ford parts counter, if it's available.

I did the brush on stuff on the underside of my rear wings when I built my car to try to prevent star cracks in the GRP. I did a few coats but it is chipping up quite a bit after just a couple years. I doubt it would last well on the front of the wings, which really take a beating. But maybe my product was just not a good one or I didn't get enough on there. You would need a super thick, rubbery layer to perform well I would think.

Slosh is definitely a factor. The starve doesn't happen until after a certain amount of time on track; quicker on stickier tires, slower to happen on less sticky tires. I think I will just drop in a new pump and see what happens. Simple job and no complexity added. The only challenge is that stupid little connector. Oh and tariffs. Thanks all for your guidance. If the pump doesn't fix it, I'll be back, probably ready to redesign the whole fuel system. Shudder...

I mean, I hate adding complexity, and I'm extraordinarily lazy/dislike "projects" or "upgrades", unlike most of my car-modding/racing peers. So my inclination is to just drop in another pump, if that's likely to solve the issue. It just seems odd that the pump would already be failing in a 4 year old car with 5k miles on it, when they go for 150k miles in a focus/etc...

I don't have a port on the rail - will a port/bung need to be welded on? Also what do you recommend for a simple datalogger?

I fixed the float, which fell off into the tank. I have that external fuel pump module thing on outside of the tank. I'm just not sure why I this issue arose. I never had fuel starve before. What is likely to be failing?
