What type of Fuel Filter?

[nemo834]

Does anyone know what type of fuel filter goes on an 88 Classic 345 with chevy 454? I know I should be able to find this at local parts store but the kids that work there are not going to be able to find my 345 in their computer. At least I hope my issue is just fuel filter?

Just go in and ask for a filter for a 1988 Chevrolet P-30 chassis truck with a 454. Every parts store I've been in has listings for the P-30 chassis.

You might consider getting the extra large 2 quart version of the oil filter. Gives you more oil capacity which provides a little better cooling. Worth it in my opinion.

Hope this helps.

I just replaced my old, worn out "plastic" fuel filter and used a new NAPA metal canister one for a '79 454 P30.
I like the suggestion of a 2 qt. oil filter too. That means I would be using 6 qts. total in an oil change, right? 4 + 2 ...4 in the pan, 2 in the filter?

Darned if I can remember how many quarts our 310 takes but it seems like its more than 6 when using the standard filter. I usually just keep dumping oil in until it reaches the full mark.

A retired mechanic friend of mine told me these big blocks use the standard 5 qt. oil pan...4 in the pan, 1 in the filter. I almost overfilled mine since my replacement dipstick was inaccurate. He said that overfilling to an inaccurate "higher" full line would cause the oil to foam by being churned up by the crankshaft, thus reducing the lubricating effect of the oil. Obviously, an erroneously reading "low" full line would mean not enough oil.
Next time you change the oil, count the qts. that you put in. If your stick is original, you should be using only 4 qts. in the pan if you keep the filter on.

According to the 1984 310 service manual provided by Airstream the 454 engine uses 12 pints which is 6 quarts. With the larger 2 quart oil filter it would be 7 quarts which is what I put in. Which also matches the fill line on the dipstick.

No disrespect for your mechanic friend but most of the 454 powered vehicles that I've had (5 of them?) used 6 quarts during an oil and filter change.

Wow, did I miss the boat on my first two replies, I just realized you were asking about the fuel filter .

On my 84 310 motorhome there are three filters. One inside the carburetor, one between the fuel pump and carburetor and one just after (or before?) the electric pusher pump towards the rear of the chassis.

I believe the two external filters are 3/8" inlet/outlet size. Any good quality filter should work for you.

Sorry about the mix up with the oil filters.......

Hey guys

Thank you for the info. It was the fuel filter that got trashed up but the standard filter from parts store replaced it perfectly. I keep a couple with me just in case there is more trash in the tank. Thanks again

Well, even though the fuel filter issue was answered, I think the oil pan capacity one is a good topic for a new thread. I know that the owner's manual states that the 454 should use 12 pints (6 qts.) of oil, but did anyone notice what they say about the 350? It says to use only 8 pints...that's only 4 qts! There may be a typo somewhere! I'll start a new thread.

When replacing the fuel filter, is it the correct procedure to loosen the smaller nut on the fuel line and then the larger nut on the carburetor? Both go counter-clockwise to loosen?

As part of my new owner updates, I wanted to replace the fuel filter. I cannot get the smaller nut on the fuel line to let loose! Turning the other nut would only twist the metal fuel line.
