I added a pump to my diesel fuel line because pushing fuel before it reaches connections (as opposed to pulling fuel at the engine) is less likely to result in unwanted air being introduced into the line.

This type is commonly used in smaller displacement vintage car restorations, and would assume aircraft. Reputable brand, very basic. At C$60 buy two and keep one as a spare. https://www.aircraftspruce.ca/catalog/pnpages/40106.php?gclid=Cj0KCQjwvO2IBhCzARIsALw3ASpONQOKjx8iPBFkovKXohPDNEeRiZQF7H6kvcQa4CIHv4rFnw6ryIQaAvV8EALw_wcB Any reason that this would not be suitable? FWIW - I replaced my original 2GM20 yanmar mechanical fuel pump this season, and only after the priming shaft O-ring began to seep. Didn't really see the need to go to an electric pump and I like the integral priming lever. Not sure why folks seem to convert these to electric pumps if the OE pump is long lived, self powered and integrated with the engine? Any thoughts?

It cost around $110 then. The original on my boat was black and had no markings so the counter guy selected a pump with low a pressure rating which matched one used by Nissan pickups.

In the US, a NAPA store can get them for about half the price. Mine was about 125$. Now I'm waiting for a cool day to get below and install. My engine is the M25XP but I would imagine that it wouldn't be any harder for the M4-30.
