rich do you have a regulator for your lift pump pressure?

I am thinking about using a holly red fuel pump with no bypass or regulator as a lift pump. Mounted in the factory location similar to yours. The pump only runs a max of 7psi, so it seems like a regulator is not needed.

I'm using a Walbro FRB-5 reciprocating pump rated @ 8-11 psi. It runs well with or without it. I use it more in the winter & very hot weather. My fuel gelled last week @ work resulting in a no start. Questionable fuel + I forgot to switch the pump on as it would've helped. The battery also failed as it was 8 years old and 5 different cars. I replaced it with an Advance Auto AGM H6
http://shop.advanceautoparts.com/p/autocraft-platinum-agm-battery-group-size-h6-760-cca-h6-agm/10210829-P.
It's a little taller and fits snug. Back to crisp starts.

ah, that walbro looks like a nice pump, and rated for diesel too. So no regulator, just pump feeding the injection pump?

Seems like that might work well. I think my 10mm pump will need all the help it can get to keep up with the holset turbo.

My fuel also gelled on my mk4 and tractor last week. It wasn't cold enough that it should have been an issue. I think that the suppliers must have been late switching to winter blend?

Same happened to me tuesday morning, then I unknowingly put a hole in the return line that has the plug on it on injector 1, resulting in me not being able to prime the pump the next day, killing the battery, and finally towing it to work where a mityvac got it running and I discovered the leak....thanks sunoco summer diesel in January....FML only two time the golf has left me stranded.

Tuesday it was about º5 that morning. I've found winterized fuel to be more foamy and harder to fill on a B3 Audi. The last tank wasn't.

my mk4 has never gelled before, and it was run in -35F a couple times last year. Granted I did run antigel in that temp. But when it got down to around 0 last week, I saw several diesels dead on the side of the road. Luckily I got diesel 911 into my tank before my car completely died, and it was able to keep running.

I used the PowerService 911 also; I drained the filter put some in, used the lift pump & bleed screw to evacuate the air. It worked great. My Cummins coworker mentioned the 911 stuff by chance the week before.

I keep it on hand in the winter just in case. I always run antigel when it gets below 10 or so. This was the first time the TDI ever needed it, but my tractor had gelled a few times on me when plowing in very cold weather. The 911 works magic, especially if you can get it in before things completely plug up. I'm guessing its not good for injection pumps, so I dont use it unless I HAVE to. Glad I had it last week! I usually have problems with the tractor at the beginning of the winter because it usually has some summer fuel in it still.

This car is the first one that's ever gelled. Both times it was @ 1/4 tank. I have no fuel pre-heater for simplicity sake so that doesn't help.

I finally skinned my gutted cat.; meaning I had my local welder replace it with a straight section from an old downpipe. It sounded noisy like a 2 stroke expansion chamber and prevented smooth exhaust flow. I always knew it wasn't optimal, just didn't realize until recently how much it could negatively affect performance. It's definitely quieter, I'm not sure but the acceleration seems smoother.

interesting you guys are seeing gelling...is that a supply problem? I've been driving diesels in Canada for a few years now, my dad daily drives sprinters and I've never heard of a gelled up car yet...

I've had no more issues, and never had them before. I'm pretty anal about keeping antigel in the tank, and I run a lot of fuel through my car. I'm thinking it was a supply issue at the beginning of the season.

Rich how many miles on the swap now? Still loving it I'm assuming? I might actually be able to drive mine soon, the engine is now connected to all 4 wheels!

I've used PowerService in my diesels for 25 years without problems. I would say it's a supply issue mostly and also it's only ever happened with this car. It was 15 below the first time in 2014, this time it was only 5º above. Both times the tank was between 1/3 and 1/4, so I keep it full as possible.
There's 35k on the swap now, 3 1/2 years on the road and I smile every single time I get in it. There is nothing else I want to drive now. I brood when I have to drive anything else. It's definitely not for everyone but I love this car.

The Glacier Blue has been on the road for 4 years and 44,000 miles last week. It runs excellent, starts crisp on the first revolution every time. The last 3 tanks were over 50 mpg; zero oil consumption @ 5k oil changes. The body is at 212k and has remained rust free, the solid Delrin+Acetron CA bushings are a little noisy sometimes; the tire wear is even. The bushings and the manual rack have a stiff, firm, but quick, steering feel I will never give up. I still hear and feel some driveline noise with the solid SF bushings, etc. I'm used to it. The stock muffler’s now on; the Stebro is back on the ’89 black 80. This car has been very reliable, 800 miles per tank every fill up. Today was 16.54 gal. for 824 miles = 49.93mpg that included some city driving.
Rich

The right front wheel bearing has lifted its voice above the regular background noise to gain my full attention. I was pretending it was the cold weather, noisy snow tires, solid everything bushings, etc. for about week now. I got down to it this afternoon.
Image
I ordered some wheel bearing removal tools because my local machine shop has disappeared since I last looked. We will see how it works out later in the week. I changed the oil yesterday; engine has now 50k.

I turned 55 in February and retired 2 months ago after 32 years working for the State of New York. I definitely now have more time on my hands to finish projects. This morning I installed an AAZ K14 turbo rebuilt with a billet compressor wheel. It pulls very smoothly to the 20psi MBC setting. The car runs perfect every start, has 55k on it since its 2012 creation. I am now running195/60-15s for the first time and they are not too heavy for the manual rack. I used 185/60-15s previously. No difference in steering effort; car handles much better. I’m using a set of really straight Speediness from dean16v. I drive the car daily still, mostly just to different hiking trailheads here in the Catskills. The black Shady 80 is coming back into driving circulation and eventually will get a 1.6TD or the ALH motor way down the line. The fuel mileage hit a new high of 51.8 mpg yesterday; 15.8 gallons in 819 miles. I adjusted the pump timing back to .905mm which makes it less noisy. The car has 225,000 now. I’m ordering a CQ master cylinder to match the G60s finally. Anybody know if I need to adjust the pushrod or should it bolt right in?
