New to the V10.. Low fuel pressure
HI everyone. We recently purchased a 2001 motorhome that's based on the F53 with a V10. I noticed that it seems to be hard to start and while it has a strong cranking action, it takes a bit to get it ...

Another vote for seriously considering using the old sender/mount hanger assembly and just replacing the pump cartridge. Although most net searches will return a variety of brands of pump, I believe most OEM get their pumps from a root manufacturing source called Walbro (a USA pump manufacturer) and put their own sticker brand on it.
All the pump has to do is pump enough to support the HP range. Your V-10 has around 300HP and it takes a certain amount of gas to achieve that over a 4 cylinder for instance. That 300 HP puts you in the range of a common 255LPH (255 liters per hour) pump which will support up to 500HP. The excess fuel is returned via the regulator and return line, or the pump voltage is adjusted/pulsed to furnish what is needed, very little at idle, a moderate amount at mid-throttle for instances. Modern F.I. may seem complicated but it is far from rocket science and all world vehicles now use essentially the same tech for port injection (such as the V-10).
Such pump cartridges may sell direct for little over $100 and, being an OEM supplier, Walbro has always been top quality in the past.
As an example, here is a Walbro 2003 F550 V-10 pump for $108. All 2 valve V-10's are similar HP and the small-truck-only 3-valve HP are just a bit above at around 360 HP, both V-10's same size pump catagory however.
You will probably find that your Motorcraft cartridge will fit by itself if you cannibalize the new one and want to blow the big bucks on it. Otherwise you should be able to find Walbro pumps here: walbrofuelpumps.com. $99.99 with free shipping.
Good luck.
P.S.
I forgot to mention that some gas tanks when left parked for a long time (without adequate fuel submersion) tend to rust the fuel level sender which is usually part of the hanger assembly. In that case your fuel guage may be inaccurate and you will benefit from finding a new hanger, or at least proper parts to replace the fuel level indicator part.
