Trouble starting when engine is warm

spectre makes it. I dont know what carb you have, but I used PN 29883 and 59013. I didnt need 29883, but it does have the fitting for the gauge and it insures the gauge wont move around from hose flex.

Fancy web site. I bought that unit from Amazon, I'm on that 'Prime' trial thingy and get free shipping so... ALso got a book on the Rochester Quad just to make sure all is good there.
Now... Must... Put... Away... Wallet.....

Put in the Spectre fuel pressure gauge, after the pump, used teflon tape and made sure that there were no kinks. When I started the truck (cold) the gauge was bouncing from 4 to 7. The bounce was fast, could hardly see the needle. After the truck warmed (10 min @ idle), it was bouncing from 1 to 9, the bounce would broaden in range when I would accelerate, 0 to 12 (hard to tell, it was bouncing so fast) now after some revs and another 10 minutes the needle finally settled to 6 and drop to 5 or 4 with slight revs (the drop is from less backed up pressure because the carb is pulling in more fuel?).

Is this initial bounce thing normal? I'm letting the truck cool and will start her up again to see if the bounce is back. From what I've read the steady 6 reading sounds like a good place to be, right? ((Roch Quad w/ mechanical fuel pump)) Also, I took the carb fuel filter out and it looks kinda dirty but I'm not sure what it should look like, anyone have any pics of a dirty carb fuel filter (what is this one called) and a clean one?

Thanks again!

gas will eat up the teflon.

the bouncing could have been caused by a air pocket.

6 psi is good.

if the filter looks dirty, then clean it. is it discolored, or are there particles?

[devanray]

Should I take the teflon off?

Some particles, the color is hard to say, its darker brown than the pic I found online of a new one.

How do you clean a fuel filter? Carb cleaner or something?

A new filter is only about $3.
