Fuel pump help

[nsa]

My car came with an aftermarket Airtex E8000 fuel pump:



It's only 18 months old but is already very noisy, even when isolated from the bracket. It sounds like the bearings have gone. It's a very cheap unit ($70) and I'd like to upgrade it, but have tied myself in knots learning about flow rates and pressures.

I gather these are the important specs:

GPH (Free Flow)30
Max Pump PSI (Not System) 70-95

Am I correct in thinking I should stick to these values when buying a new pump, and that I should be able to buy adapters to sort the rest? What flow rate/PSI can I go up to?

Hose barb inlet Size .470
Pipe threaded outlet M12 x 1

This is the car:



It's a 1977 TE61 Trueno, using the 2T-GEU 1600 DOHC engine with Bosch K-Jetronic fuel injection. The same engine configuration was used in a 1983 Celica (GT?). The previous owner approached Bosch for help but didn't get much back. I want to see if I can get some advice here before walking into my Toyota parts dealer in Hong Kong. The car isn't used on track and isn't even driven that fast around here.

Thanks.

Thank you very much both. The pump is externally mounted but I think it's intended to be that way. Noted David, that's exactly what I wanted to hear.

New external Bosch 580 254 911 pump sourced for £60 and fitted with a new clear fuel filter between pump and fuel tank. The old filter had a lot of rust in it and I suspect it was much older than the noisy pump. Fuel runs clear through the new filter.

Thanks again.
