tank mods?
Fitting an ej20T to a buggy...Rather than run a surge tank, lifter pump regulator etc...
What woud stop me from just getting a new beetle tank (they're cheap enough) and modifing it with a baffled sump, in tank pump and new (bigger )
ports?
If my research is right , I just need a 10mm out, a 8mm return and a vent to a charcoal canister... Is that it? What's wrong with this plan?
The fuel supply line is only 5 feet long and under heaps of pressure, so I can't really see fuel starvation being an issue. A uprated in tank pump is
available.

Nothing is stopping you, it's a good idea. I'd like to do the same with my car one day. You just need to pay attention to the surge pot that you
make inside the tank. 8mm fuel lines in and out are big enough for standard HP requirements (unless it had a 10mm supply standard).

Yeah my rat buggy, i bought a brand new tank ($80) and just put a few more fittings onto it. I also put a surge tank etc underneath. Turbo mick
simply has a VL pump under the stock tank with no surge tank, he had no dramas even when going up steep dunes full throttle, I think he just always
kept the tank at a decent level.
My new build has a sharpbuilt alloy tank with baffles taking the stock subie intank pump, this has all the hose fittings on the pump itself.

I made an internal surge pot using a bit of 3" or 4" exhaust pipe (can't remember which now - did it 10 years back). I used a couple of old tanks.
An early oval top and a late bottom, to give more capacity. The old tank's bottom was knackered anyhow - just getting in before the purists lynch
me. I filled both tanks before cutting them in half - I believe even long empty tanks can explode.
I also added a size limiting plate in the fill area to fully comply with the regulations at the time for registering the car as an "unleaded"
vehicle.

I'm with you - doing it right at the tank should mean no need for surge tanks at the back and all that stuff.
Wasn't there an EFI beetle? Wouldn't that have an in-tank EFI pump and the required fittings, along with a pot already inside the tank?
I'm going to go the same way with my EJ20T install - nice n clean. I remember converting a Mazda 808 piston engine car to RX3 rotary - the 808 tank
already had an electric facet fuel pump in it. I just added a Bosch VL turbo pump to the outlet from that pump, high pressure hoses, filter and
regulator at the front of the car and connected the return line up. It made 300hp without ever surging or running lean.
Reversed gears for Subaru transmissions.

Something I thought might be worth mentioning. Any Fuel Tank modifications require a Blue Plate (Mod Plate) in QLD.

i did that on last tank....cut a hole in the top...put in baffles and welded it back up. then ran vl pump externally.
Better than baffles is sticking tank foam inside. thats what i have done with the new alloy tank i hve made.
