Dear maplebones,

Hope you're well and stay so. The Volvo Pocket data booklet Cars (700, 850, 900), 1991-1996, does not list any pressure parameter for Bosch fuel pumps.

The only fuel pressure datum involves the system regulator, which is 300kPa ( = 43.5 pounds / square inch). I'd guess that the in-tank, pre-pump operates at a lower pressure.

As, however, fuel delivery is mission critical - and a fuel hose failure creates fire risk - I thought it best to suggest use of a hose that is rated for full system pressure.

Auto supply stores sell fuel hose by the foot or in pre-cut sections of varying length.

In general, I'm reluctant to try to economize on hoses, whether for fuel or coolant or power steering.

Hope this helps.

Yours faithfully,

Spook
