I am one of many who converted from carb to TPI. I am also lazy and choose not to pull my tank again to install a fuel pump, so I went with the in-line pump.
Well, in-line pumps do not have checkvalves so the pressure drops to zero instantly when the car is off. Makes for extended cranking times.

I solved it by buying a $12 in-line ball check valve (brass) and installed it today. Guess what, it works! I'm so proud of myself. The hardest part was finding one snd I found one at this site:

Do a search for "compact ball check valve"

JM,

Thanks for replying with the results. This will be very helpful to remind us all that a good fuel pump is necessary for proper starting. We are always eager to blame a stuck injector or bad FPR for the inability to hold pressure, probably since none of us is fond of changing fuel pumps.

If I'm not mistaken, I recall the discussion about your fuel problem but I can't seem to fing the thread in the archives. If I gave the customary advice, I probably mentioned checking the fuel pump pressure and leakdown tests, including pinching the return and supply hoses. Sorry if I missed that one.

The McMaster-Carr catalog is a good source for a lot of hard-to-find parts. I use industrial suppliers almost daily, and another good source is MSC - http://www.mscdirect.com . They have a similar line of products. Between the two of them, Grainger, and your local industrial suppliers, you can find a lot of creative solutions to mechanical problems. Another good resource for locating products or companies is Thomas Registers.
