Power Steering Pump reservoir cap???
 

Our truck ('79 F-150 4x4 351M/Auto) doesn't have a cap on the power steering pump reservoir (we have the plastic reservoir not the metal one) and we can't find/figure out where to get a cap for the reservoir. . .I've seen the dipsticks for the power steering pumps but I don't see where it goes on our steering pump. In all of the online pictures of the power steering pump that I have seen (Autozone, Schucks, etc.) there isn't a cap on it either. What kind of cap is the reservoir supposed to have and where can we get one. . .we've already been junkyard scavenging for one. The only one that I've seen come with a cap is the Extra Duty version but it's way more expensive (twice as much) and we just don't feel like buying a whole new Extra Duty power steering pump when all we need is a cap for the reservoir.

Same question for a dipstick for the engine oil. . .ours came without one and I can't find one for the 351M anywhere. . .I got one from the junkyard but it didn't fit (I didn't check to see if the truck I got it from was 4WD or not so I'm guess that the odds worked against me and it was 2WD so it won't fit our 4WD oil pan!!!

Thanks FTE!!!

i think ford rangers and explorers have the same pump, it is a common pump. 351m, 400 same dipstick.

1978/79 F100/350 & Bronco P/S Dipstick
 

YF1Z3A006AA .. P/S Dipstick ~ Use with the FORD type P/S pump / Replaced: E6DZ-3A006-A, E1AZ-3A006-A/B, & the original 1978/79 p/n of D8AZ-3A006-A.

MSRP: $5.90 / ftepartsguy.com price: $4.25

Note: 1977 and earlier cars/trucks used a different pump, the parts will not interchange.

This dipstick is not the same one 1975 and later Econolines with Saginaw P/S pumps used.

Your didstick/cap looks like this look at this one

As common as can be used in all plastic tank saginaw pumps. You can find them from 79-97.

I got one you can have.
