Turbo's MK4 build adventure

Welcome back. I have a walbro in tank pump. You’ll likely need a high volume pump with the bigger motor. Ask Mike Forte who can set you up with everything you need from the pump to hanger to flex lines and fittings

Trying to get the engine moved to the car today - but when trying to slide the driveshaft on, it only advances a few centimeters - but then hits a hard stop. Tried nudging it with the "persuader" but no luck. I don't see any obstructions. What gives? Any ideas? Thanks all!

The manufacturers sometimes put a rubber donut on the output shaft. This puts it inside the housing past the tail shaft seal.
Slide a small screwdriver up the one of the spline grooves and see if it bottoms out. If so, you probably have the donut on the shaft.
It requires you pulling it out, without damaging the seal. It helps if the output shaft has some light oil on it.
If you can cut the donut it helps.
Small needle nose pliers are one of the tools I used.
Use your imagination on what will hook or hold the rubber as you pull it out.
If you do not have the donut on the shaft, put some gear lube on the spline and/or inside the yoke spline.
They do not like to mate dry.
At worst your spline could be wrong. Not something you hear often.
good luck,

Thanks Railroad - but no rubber donut. Still can't get the driveshaft slid onto the shaft. I don't see any obstruction - but it won't advance more than about a couple of inches - seems to hit a hard stop. Everything else looks good. On the driveshaft, there is a space where a single spline is missing - wondering if this needs to line up with something? Grease didn't really change the situation. Thanks all for any help you can provide! Here are some pics too.

Driveshaft: Stock new from Factory 31 SPLINE 2015 IRS 8.375” drive shaft

The output from the transmission doesn't fit the driveshaft - see pics. I'm sure this is a rookie question - but is there an adapter or other piece I'm missing? Thanks all!

Yes, an adapter is required. Should have come with your IRS parts. It bolts into the differential flange and then the driveshaft bolts onto the adapter.

Just curious if this fuel pump requires a special fitting for the inlet and return. The threads fit my male AN-6 other fittings but the female ends on the fuel pump seem really deeper than any of my AN-6 fittings. Is there a special AN-6 fitting that meeds to be used for this? Thanks fellas. IMG_0464.jpg
