Awesome !! That's great !

Brand new mech fuel pumps are all junk, most fail very quickly, none prime the IP, that allows air intrusion if there's anything not perfectly tight.

Low pressure, When it fails not if, the truck will stall out, not prime, or dump fuel in your crankcase.

Just keep or upgrade the epump, and or get a spare to keep in the truck if you're concerned about it.

Sounds good to me! Do they make oem ones anymore, or worth it to look for NOS? E pumps look cheap enough!

Edit: I found the international part number, and see some that are available. May snag one just to throw on the shelf...

I mean, it doesn't hurt to have a spare.

But it might also just be in a oem box

But Nah, I wouldn't use it, for sure, just save yourself the heartache and trouble later, and invest in a good epump, facet is know to make good ones, also the ones they use on thermalpac trailers are good.

Whichever beefy pump you choose, doubly be sure to get a genuine one and not a counterfeit, They're out there. Choose a reputable supplier,

Also, keep in mind, fuel hoses and fittings, o-rings, have to be diesel specific, don't use gasoline fuel hose, you'll need diesel hose if you add any fuel line.

Our diesel engines like low pressure high flow, not like gasoline fuel pumps, so check the specs, diesel, 4-7 is generally a good PSI range, more than 3, less than 10 is okay.

I would recommend installing a fuel gauge also, they're super handy to be able to see what's going on.

i use and recommend the facet 40222 pump.
the best price now is from pegasus racing at $120.39
https://www.pegasusautoracing.com/pr...asp?RecID=9705
the facet pump was designed for refrigerated trailers and can straight up lift 10 foot to the engine.
while the 9-11 psi pressure is a little higher than the 7-9 psi ford recommends, it will work fine. the most you will have to do is bump the timing a hair.
i have been running one for around 250,000 miles / 21 years on my truck. .i run a turbo since new, and have it bumped timing a bit for the extra fuel pressure with fuel screw turned up 3 flats.

parts store electric pumps, work for a while, but usually die within a few years.
the facet pump is a bit expensive, but worth it.
just like the stancor monster glow plug relay at $79.99
https://dieselorings.com/products/16...low-plug-relay.
i use the stancor relay as a starter relay too. the one on my 88 is still going strong 25 years now.
i feel buy GOOD parts once instead of buying so so foreign made parts many times. in the long run you save money by buying the good part in the beginning.
best part is, both the facet pump, and stancor relays are still made in the USA

x2 on sticking with the electric fuel pump.

Looks like a great OBS truck. Let us know when you get her home.

Thanks for the responses. Totally for the buy once cry once! It currently has a facet 40290, which in their catalog reads a minimum of 12 psi, I assume he has the wrong pump in the truck then... Good to know about the stancor relay, and diesel rated lines.

the 40290 should work fine, if you can retard the timing enough.
fuel pressure on these engines adjusts fine timing in the injector pump.

When I get to the truck I will bug the fella selling it to see what he did for it. If I do end up purchasing, I have to wait for a couple hours probably, for Canadian insurance. Will be able to give it a real good once over before the long trip back. Do I need to worry about egt's with these trucks? Will be driving the mountains home. I assume don't lug it, and should be alright?

if it has a turbo, it should also have a pyrometer(EGT gauge) you want to keep EGT's under 1100 degrees.
and yes, dont lug the engine, especially in 5th gear.

And if it doesn't have a turbo, you wont have to worry about lugging it on the mountain passes, because you'll have it to the floor in 3rd or even 2nd, against the governor, just to hopefully maintain the speed limit haha. In this case, the EGT's will be low, with such high rpms, but you'll be happy to know, you can hold them against the governor screaming (as much as an IDI can) without hurting anything for pretty much as long as you want.... so long as the cooling system is up to par and can handle it of course... Which reminds me; Ask about SCA maintenance.

Sweet, sounds like I do not have to worry about EGT. For SCA's I remember I asked him and he said it was his buddies truck, and he kept up with that, he's only had the truck a little over a year supposedly and hasn't touched the cooling system.
