Did you have to cut out that area in the tank where the cradle sits inside of?

or atleast remove the plastic filter on the outside of that area so fuel flows in quicker?

I've noticed both the Bosch 040 and Walbro sometimes struggle in high revs, I'm sure it's just more dirty in my tank, but while using my fuel pump to empty my tank for cleaning, I noticed both pumps can empty that area a tad quicker than it seems to refill when the plastic basket is on the outside ?

What did you do after that?

With the bosch and a heavily modified cradle I can get it about 5 - 10 mm away from the bottom of the tank.

Did you raise the height that the pump sits at?

I really don't want to have to clean my tank again but the sock keeps getting clogged. Hoping that if I use this Walbro pump and raise it up higher that I won't have the issue anymore.

I had a 040 in mine. It ran fine, but it was loud. I got mine down to about 10mm off the bottom of the tank. I switched to a walbro because the noise was driving me crazy.

I dont know if it made any change, but I pulled the plastic baffle out of mine when I switched to the walbro.

I put a walbro in mine about 5 years ago, never had a problem with it... except that I get fuel surge on a particular corner when I get below half a tank.

I've since added a surge tank and an external pump in the boot.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
