Webber Carburator Fuel Pump

[Tonka]

Hello,

Just ordered a 32/36 Carb after reading alot on these forums on how highly regarded they are, especially compared to the overengineered Mikinu. This will be my first time really modding a vehicle, I've only ever just replaced parts with stock, so venturing into this territory is a bit new for myself.

I had an inquiry. I am deleting the mechanical fuel pump and installing an electronic one. I'd like to replace the fuel filter considering the addition of the Webber and new pump. Just I am conflicted if the filter should go before or after the pump. If after, I could use the stock filter and just replace it, if before, I've seen a video use this filter, which I'd just rig before the pump. I've seen some use a filter before and after, but logically that doesn't make sense to me (if its filtered, its filtered, right?).

I also have some questions on EGR/emmissions, and vapor lock and how that works. But currently I'd just like to start with the basics.

Thank you

I used an Airtex pump and installed it under the skirt behind the driver side of the cab. I kept the OE fuel filter and have recently rewired it with a relay kit from the interweb. It works better than the oil pressure switch I originally went with. Here are pics of how I installed the pump. I used a piece of sheet metal bent it to fit and bolted it in when I got the mounts on it.

Looks like that pump you chose already comes with a screw-in mini filter on the intake side, so you could just stick with that.

For replacement filters, looks like that unit would be a Wix 33046 or Mr. Gasket 1242G (or other equivalents).

Oh, haha, I feel pretty silly now, canceled the order. That makes me feel a bit better. Is the OEM filter neccessary then (As in, do I need two filters)? I'll be replacing it if I keep it.

You won't need to keep the OEM filter, since that was a pre-pump filter for the mechanical fuel pump attached to the engine, and your new electric pump already has a pre-pump filter of its own.

I would keep the oem filter. Bigger and better than the little ones that come on a pump. Doesn’t hurt to have the big one before the pump.
