discovered my fuel pump is leaking, havent had the chance to pull it out and have a close look, but from crawling underneath the car it seems to be leaking from the pump. a buddy says id be able to replace the seals or possibly have it rebuilt. where would i be able to get these seals, or where could i get the pump rebuilt? not quite fond of the price of a "new" pump. OR could i just replace the one on the 14 with a pump off a bus?

Finding the right seal is the problem, NLA. Plus they're a PITA to take apart.

I think the bus one will work, but if you have a 3 barb pump (-74) you will have to use a "T" in the line for the return hose.

Unless you have +$200 for new it can be fixed with a couple of O rings from the hardware store. After you pry the tabs and split the housing apart the housing oring is easy to change. The one that leaks is around the terminal plug its easy too if your good with a solder iron. Mine had alot of brush wear on the armature but keeps 32psi pressure at RPM's. Also +70psi test return hose at regulator pluged. Pic of freon shradder valve silver soldered on the OEM test port.

What does this mean ?

would there happen to be any DIY diagrams online?

at the test port I sent above pic of normal pressure 28 to 34psi set with regulator. A test of the pumps power I read was to pinch off the return hose turn the key on for that 2sec pump run but do not start this way psiag should go as hi as 55-60 Dont run it at all with the return hose pinched off.

Gotcha. Gotta be careful on what you type.. lots of people watching might have thought you where running the car without the return line hooked up.

i know this is obvious but, what type of a gauge would be used to test the psi of the fuel pump?

a small favor, could i get a general listing of a few brands of fuel pumps used on a 1.8 FI?

Any gauge will work, I have a water pressure gauge from Home depot and a few adaptors. The best gauge fo us would be a 0-50psi gauge.

OEM pumps are all Bosch, -74 have a 3 barb pump and is quite spendy, 75- uses the 2 barb pump (like in the VW buses) and it's about half the price.
